General :: Java Apps Slow Startup When Connected To Network?
Aug 11, 2011
I'm using Arch Linux with kernel 3.0 and brcmsmac to manage my wireless card. My desktop environment is KDE 4.7 and I use networkmanager to handle network. Recently I've been affected by a weird problem wherein whenever I'm connected to a network Java apps such as jEdit take ~30 seconds longer to start but behave normal once started. What could it be due to and how can I fix it?EDIT:The problem occurs both with Oracle's JRE and OpenJDK, both versions 1.7. I'm behind a HTTP proxy, if that makes a difference.EDIT:I've discovered the cause of this problem. My /etc/hosts file had the wrong host name in it. After correcting this to my hostnameeverything is fine.
We are attempting to convert our entire office over to Linux, however we are experiencing some printing challenges. We have a Sharp-AR-M205 connected to our network that handles the bulk of our regular printing needs. Linux picks this up from the network and installs the driver (Sharp AR-M205 Foomatic/pxlmono (recommended)) without difficulty. We can print from gedit & OpenOffice without difficulties. The difficulty is when printing images, webpages with image content, or PDFs.
Then the printing spool goes into "LPR ..." printing mode and takes between 5-20 minutes to print a single page. This is particularly problematic as each week we put out a simple publication for our organization, designed in Scribus, outputted to PDF and sent to the printer from 200-300 copies. Our workaround has been to leave a workstation as an XP machine to print the PDF each week.
I recently installed OpenSUSE 11.3 amd64 from DVD on a new HP 625 Laptop. Whenever networking is activated, application startup slows down significantly. When I deactivate networking in the nm-applet application startup is fine. I am using the broadcom-wl package from packman for the broadcom wireless card (BCM4313)
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
I'm an Ubuntu user since Jaunty, and I've always upgraded my system (NOT fresh install). Everything went fine, but yesterday I upgraded to Lucid. My only concern -for now- deals with startup time. I'm a desktop user (Core2@3GHz) so I think I should boot in less than 10 seconds. Anyway, boot time is 30 seconds - not too much, but there is definetly something wrong with tools I don't know (ureadahead, plymouth, etc.). Attached is my bootchart: can anyone explain me what's wrong?
Also, I don't even see a plymouth Ubuntu themed bootsplash: I only see a blank (black) screen standing for seconds, then I see the bootsplash for less then half a second, then GDM appears :S Not crucial -I know- but how can I fix it? (I don't know if it's related, but I can see the animation at shutdown)Finally, GNOME desktop takes too long to load. I don't know why, but there are 15/30 seconds in between login sound and a usable desktop (with panels and icons, I mean).Please help me, I don't want to do a fresh install. Boot speed is not a dial with desktops - I know - but it can be a symptom that my system is a bit a messy (and I don't like it, since I installed Jaunty less then 1 year ago). (!Forgot! I also installed grub2 by hand
Just got this Dell M4400 with Redhat EL5 installed. After I setup the xorg.conf for dual monitor, the startup became extremely slow. Once I type in the user name and password, it just blacks out with the mouse curser still visible. This remains for about 3-4 minutes and then I'm in.
I thought it was my X file, so I overwrote the xorg.conf with my original file and restarted my X. Sadly, it still does that.
What could be causing it? Do I have to reinstall video driver or something?
I just installed a game, TripleA, that is supposed to run great on Ubuntu using JAVA. I extracted the game to the recommended folder.I have JRE already installed via Install and Remove Applications utility. Is there something else I should do? Installing JRE manually seemed a bit troublesome.Is it "safe", i.e. will the other apps that use java still work properly?
As xnee official packages did not work for me, I downloaded, compiled and installed the latest xnee version (3.06). It work almost well, but if I try to automate the execution of a Java web application, xnee lost the synchronization and give me this error:
Code: Can't synchronize anymore .... have to leave! 11 10 Error number: 5 [code]...
I have an external Samba network storage drive that I mount using 'mount -t cifs -o username=aaa,password=aaa //myserver /mnt/mountlocation', but I'm finding it to be a pain to enter that whole command every time I turn on that drive and connect it to my computer via the network. I could put that command in a script and run a simple script like 'mntdrive' that would run that command for me, but is there a way to have the drive 'pre-mounted' so that if it's available on the network it's mounted?
If I put the mount command in one of the startup scripts or in fstab, would it be available at the mount location when the drive is connected if it wasn't connected when the computer was first turned on? Or is mounting the drive manually, even if by running a script that does it for me, something I'll have to do every time I turn on that drive? Any creative ways around this? Would make things easier if it is possible.
I did a install of 9.10 on a Lenovo T61p a few weeks back. The install went seamlessly and everything was running along just fine, then suddenly, I'm having the problem that every time I go to launch a new window, it takes 30 - 40 seconds for the window to launch. Once the window is launched, performance seems normal, with one exception. When I go to launch Nautilus from the "Home Folder" menu under "Places", it takes 30 - 40 seconds to launch the window, then another 10 -15 seconds for the folder items to appear. If I click to descend into a folder, it takes 10 - 15 seconds for the folder contents to appear. This stuff was all instantaneous.
Basically using Chrome on my Ubuntu 10.0.4 I am having trouble playing games such as Bejeweled and Farmville on Facebook. They load, but very slowly, and the reaction time is dreadful (I make a move, 5+ seconds later it happens).
My computer freezes and I am trying to diagnose the issue. When.. Using Devede to convert avi to dvd. (almost always) Using Firefox on pages using macromedia flash or java apps. With multiple windows open using terminal. I am strongly leaning towards this being a HARDWARE issue.
I've just upgraded from 11.1 to 11.2. My KDE apps (Firefox, Yast, Kmail) are now excruciatingly slow - particularly Kmail which is now virtually unusable. Before the upgrade on my 3GB RAM laptop the response was great - so something has broken during the upgrade process. What is interesting is when I open in Failsafe - the speed is fine.
My thoughts are maybe graphics card acceleration but why would it be ok in failsafe? Not really sure where to start looking here.
I've Intellij Idea and Netbeans installed on my Ubuntu desktop. Both worked fine while I was on 10.10.After upgrading to 11.04 both of them became irresponsive to Ctrl+C/Ctrl+V/Ctrl+{Any alphabet letter} combinations. However these combinations work in non-Java apps (e.g. gedit).Besides that Ctrl+Alt+L (Lock screen) is not handled by the system, no matter what application is active.Disabling unity does not help. Starting in ubuntu classic w/o effects does not help either.
I need to start vboxwebsrv and x11vnc on startup with a specific username.I tried entering the commands in rc.local as:/bin/su -c "/x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800" user1/bin/su -c "/usr/bin/vboxwebsrv -b" user2.But this does not start the app on startup.
Since I switched to lucid (clean install), the interface has become very slow, unresponsive. I had no such problem in karmic. Switching from one window to another, displaying menus, browsing files, resizing windows etc... take ages to display.Now what is strange, is that this problem only affects native gnome applications.For instance Scribus or Blender run very smoothly, whereas Nautilus, Rhythmbox, Gimp or Inkscape, to name a few, suffer from those horrible lags.I'm pretty sure it's not a driver problem, I'm using the latest nvidia-current drivers, and I tried everything : disabling compiz, disabling metacity compositing, using nouveau, using latest kernels, using xorg server 1.8. No change.
So I know the problem only affects native gnome apps, but now how can I find which package causes this mess ?I just installed a few repos to have some recent graphic apps (gimp, inkscape, openshot, scribus... that's it), but I can't see in what way they could have messed with my system.
I can see the Facebook homepage (facebook.com/home.php) immediately after clicking on the bookmark. But with Facebook apps (mostly flash games) I have to wait up to 10 minutes while Chromium status is showing the message "Sending request...". This won't happen to Windows on the same machine.My Ubuntu version is 11.04. I can access other sites normally fast.Please note that I'm not talking about the flash thing but the Ubuntu networking.
The web navigation is very very slowly. The load of web page is slowly. I don't know what i do. I connect with wifi. the download with software same emule is good. I use firefox but i tried also other browser.
I have a Nook ebook reader and would like it to automatically open a certain application when I plug it in.As standard it just opens a nautilus file browser.I cannot find any settings that will let me associate a drive name/uuid with a certain application and google results came up saturated with how to make bootable USB drives.The only solution I actually found was to make a .autorun script in the root of the drive to start my application, but it still requires user interaction and is not ideal since I would like to implement this across several machines with different users/applications.
I've been trying to add applications to my "Startup Applications" menu. Most of the time, they "stick," but sometimes simply disappear, either immediately or after a variable length of time (sometimes more or less immediately, sometimes after several restarts, or anywhere in between). I've noticed that, when they stop booting, their entry disappears from ~/.config/autostart, but changing permissions on the affected files (e.g., removing write access) doesn't seem to help.
Any suggestions? Re-adding the same things over and over gets frustrating after a while, and I can't figure out why these entries are disappearing.Currently running Ubuntu 9.10 on an HP Pavilion dv6000 with an Intel Centrino Core Duo processor and 2 GB of RAM.
How do you change the order of execution of gnome startup apps?(System - Preferences - Startup Applications) does not seem to have any way to do it.I saw an archived post (http://ubuntuforums.org/showthread.php?t=659420) which offered a couple of ideas... (1) mucking around with /etc/rc2.d/ -- but that seems to be only system-level apps, not user apps; or (2) going to (System - Preferences - Sessions) and mucking around in there -- but I don't seem to have that menu on my system (10.04 LTS running as a guest in vmware player 3.1)I just want vmware-user to run before my gnome-terminals so that the desktop is resized before the terminals run.
Yes im refering to Windows Degrade and how over time windows just running will degrade and start causing errors. DLLs go missing and bizzare things. Ive seen wierd things happen on a windows machine that is dedicated to one function. Well to my point, recently I have been having many linux issues, not like normal or anything throughout the years I have experimented with linux though.
1)entering fullscreen on VMware crashes linux sometimes (no Ctrl+Alt or Ctrl+Alt+F2 ect) 2)using a different monitor haults the virtual machine while other monitors do not (I have 4) 3)Java apps freeze and require moving the window offscreen (below the screen) to redraw 4)general linux freezing 5)glitch with xinerama that repeatedly teleports mouse between two monitors causing the system to be unusable (no Ctrl+Alt+F2 or anything either)
At first I thought they were all related to VMware but they may not be. I run VMware everyday for my slingbox and light EXE-ing when wine isnt an option. So I may not be asking for fixes to all these problems but whats going on? Ive seen linux installs last years and believed linux to not degrade.
I am running Lenny. USB storage devices are painfully slow, if the data to be copied is above 4GB it works on transferring for more than half an hour and then comes up with an error dialog(saying something like file size is too big). The problem exists in both read and write.
I did google a bit and here is the output of lsmod | grep hci ehci_hcd28428 0 uhci_hcd18672 0 usbcore118192 4 usb_storage,ehci_hcd,uhci_hcd
