Programming :: Programs Run Faster Than Windows?

Jul 25, 2010

I know this may be just me being a little bias on OS's but... I quite honestly believe that "some" programs run faster on linux than on windows.

Open Office for example, It runs amazingly fast on my linux distro but runs horribly (laggy) on my Vista machine.

Firefox also appears to run faster on my linux machine than on my Vista machine.

There are several more examples but I could go on and on with this.

My point is, do programs run faster on linux than on windows? Or is it just me that is in denial?

I am not sure if comparing linux to Vista is a good comparison in terms of program speed or not...

Also it should be noted that the Vista machine "hardware" is "several" times faster than my linux machine's "hardware".

I am not trying to start a flame war or anything like that, I am just trying to make sure I haven't totally lost my mind.

Ubuntu :: Put Frequently Used Programs In Ram For Faster Startup Time?

Jun 12, 2010

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

General :: Mac-like Tweak To Make Programs Start Faster

Apr 24, 2010

I've been working with Macs nowadays and noticed that programs load like "instantly" once it has been open and closed.

I don't know if MAC is pre-fetching them to somewhere but it is good to start Firefox right after you closed it.

what MAC actually does and how this could be implemented ? I have 6gb of ram on my laptop. Running Kubuntu 10.04 RC1.

Ubuntu :: Restore Open Windows Faster?

Jul 27, 2010

I'd like open windows to reappear from the taskbar faster. There's always a delay of at least 1 or 2 seconds between clicking on a minimized window and it being restored.

At first I assumed this was a limitation of ubuntu, but I've realised since the delay is the same across the board, regardless of the application, which makes me think it's a deliberate setting.

Am I right - and if so where can I alter it?

Software :: Why Do Windows Applications Start Faster

Jan 12, 2010

I noticed that on Linux, applications are much, much smaller but they take forever to start sometimes (namely, OpenOffice). However, MS Office starts up super fast, but I see it is huge (it needs 2GB to install).

Is there a trade-off between size and start time? If so, is it possible to "enlarge" some of my programs so they would start faster? I have plenty of unused disk space, and a few larger programs wouldn't really hurt.

Ubuntu :: Windows Loading Pages Faster Using Firefox?

Oct 1, 2010

Two very simmilar laptops connected to the same WiFi router loading the same web pages. Firefox on Windows does that for 3 secons, while Firefox on Ubuntu needs 1-3 minutes to load the same page. What could be the reason for this? Any idea how to fix it? The laptop with Ubuntu runs 10.04 LTS (lucid), Firefox is 3.6.10 and on any other WiFi network it loads the web pages really faster but why is much slower than Windows now?When testing the speed on URL...Ubuntu loads times faster than Windows. The WiFi router has been reseted. Firefox has been started in -safe-mode, both didn't help.

Programming :: Association Lists Are Faster Than Hash Tables?

Jun 13, 2011

I'm writing an interpreter and it used simple association lists for mapping varaible names to their values. Here's the code:


#include "assoc_array.hpp"
#include <string.h>
using namespace LANG_NAMESPACE;


I thought that I would replace it with a hash table to increase performance. Note that I decided to store linked lists in the buckets instead of the actual values, in case the hash function outputs the same index for multiple variable names:


#include "hash_table.hpp"
#include "assoc_array.hpp"
#include <string.h>


It runs in about 0.333 seconds on my machine. Since I'm using git version control, I decided to bring back the old version that used association lists. To my amazement, it ran 3 times faster, completing in 0.116 seconds! Is my hash table implementaion really that bad, or is this a really poor benchmark (and real-world code actually will be faster using the hash table)?

Ubuntu :: X-Windows: Pointer Moves Faster Horizontally Than Vertically?

Feb 7, 2011

I've set up the Apple Magic Trackpad with my dual-scren Ubuntu system, the screens of which give me combined screen resolution 3360x1050. It works basically, however the coordinate ranges are messed up, as follows.Moving my finger the bottom of the trackpad to the top, my pointer moves from bottom of display to top.However the same is true horizontally: From the left side of the trackpad to the right, the pointer moves from the left of the monitor A to the right of monitor B.Thus the speed horizontally is 3 times what it is vertically.How can I fix this? Even if I remove one monitor (no big deal) the pointer will still move 50% faster horizontally

General :: Backing Up Windows 7 Programs?

Aug 24, 2010

I want to do a clean re-install of Windows 7 but there are files and installed programs which need to be backed up and restored. I tried using the Windows 7 backup utility to do a full backup to an external usb drive. The problem is that whenever the backup gets close to finishing, it always crashes. The system I am backing up has been compromised by viruses, which might be causing this. I already used several utilities to get rid of the viruses but some of the damage they did can not be undone. I tried doing the backup in safe mode but Windows 7 does not allow this. What other methods can I use to backup and restore important programs and files on Windows 7? Perhaps there is a way to do it from outside Windows 7, like say, using a Linux live cd? One of the main problems I see is restoring installed programs since those make use of the registry so simply copying the files probably won't work.

Debian :: Programs Open With (Blacked Out) Windows?

Aug 10, 2015

Long story short, been using Debian for 2+ years. Recently did a Clean install of Jessie (which worked fine). I wanted to test out Ubuntu 14.04 so I distro hopped for a couple weeks. Now I'm back on Debian Jessie (did a clean install again).

Problem is: Everything works fine, but after the computer runs for a while (like 2+ hours) any new program windows that I open are completely blacked out. Just like opening a big square black tile. They are unusable until I restart the computer, then everything works fine again for another 2+ hours.

I've never had this problem before, not even with my previous clean installation of Jessie. This time I installed it in the same way that I did the last time.

I have tried changing the windows version and made no difference. I have even tried opening it in a virtual window and made no difference (Window opens then closes)

I maximize it and it just re-minimizes it. What can I do to stop this?
