I am curious if it is possible to use multiple hard drives to increase server speed. I know I could run stripped drives or RAID0, but was wondering if there is any other way to do it within Linux. My default 9.10 Server install has 3 partitions as a default. Would splitting these on three drives make it any faster?
View 3 RepliesLast week my ping was 45 this week its 80. I've checked it on three different computers, and reset my router. I called verizon (my subpar isp) they run a few test, say every things fine. I recheck my ping, its back to 45 but only last 5 mins after they check it, then it goes back to 80. I'm always having problems with them, but every time I call them the problems "just so happen" to go away while their helping me.
Anyway, my question is... Is there anyway for me to increase my ping/speed without upgrading my internet? I have 3.5 upload, .75 upload, and a Westell model 327w. I know this is a general question and not really linux related but I thought I would try this forum first since its always so helpful. I have googled this subject but I only find windows related stuff that pertains only to the programs running on the machine. They suggest things like "dont download when you want high ping" and "temporarily turn off seeding for your torrents" It is most important in windows for me though, I like to play games and a difference of 50 and 110 ping does make a difference. Of course, everything seems slower, like streaming movies and stuff.

View 8 Replies View RelatedI recently decided to install ubuntu on an old PC to increase its speed and usability. Prior to this I had windows XP running on it. I installed the newest version of ubuntu, which makes the whole thing running unbearable slow. Under windows xp it was running ok, my question therefore is: which version would you guys recommend that needs less ressources, but still has comparable functionality to the new version?

View 2 Replies View RelatedI have an old AthlonXP-2600+ running at 2.078 Ghz which I was assured would do 2.6Ghz, but actually doesn't and 2.178 Ghz is what we settled on. I have 266mhz ram on a board with 333mhz FSB and we sorted that out also, and specified the ram speed. That sounds like under 10% of a speed increase, if any. But the previous kernel I built here took 55 minutes (time make -j4). The one I built after the mods (nearly same config) took 33 minutes. (make clean; time make -j4) 40%? I've clearly improved or fixed something.

How do I increase the mouse speed in Ubuntu Linux? Running Gnome 2.30.0. I've already maxed out Pointer Speed Sensitivity in the Mouse Preferences control panel. I am not interested in increasing the Acceleration. Is there a config file I can edit to boost it past what the control panel allows?
I know that this mouse can track faster because it does in Windows.
Is there anyway to increase the speed of scrolling within the unity launcher? Like when you have more icons than that fit inside of your screen. I know you can just go to the scrunched up icon and hover it and it will appear, but is there a way to increase the scrolling speed when using a mouse wheel? It seems a little slow for my taste.
I think I seen a "bug report", for this, which really isn't a bug, but more a desired option to customize the unity launcher. Just wondering if this has been figured out, or even possible.

At that point, it will never pick back up above that rate unless i disconnect and reconnect.

I run a server with nginx at the front and apache at the background. Nginx serves as a reverse proxy in here. As there were lots of DOS attacks, I have implemented Deflate-DDOS, APF and Nginx anti-ddos features and the server runs without a problem. Once every month, the load on server increases upto 300 and I receive an email like this :

There's more that 100,000 ( I suppose ) lines on this email. I have no idea what the problem is. It seems there's something with the session, but I really don't know what it is.
I am implementing a proxy server in c++. It is multithreaded(posix).Used CPU : Xeon(8core) Thread number : 8 One main thread, and other 7 thread created by the main thread. The main thread always listen to ports. When the main thread gets a client data it push the request in a queue[there are one queue(total 7) for each thread] based on ip and then give a signal to the appropriate thread. Then that thread gets the request from it's queue and process data and then forward the data to a appropriate destination.
There is another important thing, I assign each thread excluding the main thread to individual core by using affinity.The main thread listens to 5 ports. Test environment: We run the server. The client sends audio data at a particular rate.
1. The main thread CPU usage gets overloaded (above 80%) after a certain load from client.
2. Other cores remain about 0-10%.
The thing is that we want to distribute the load among all the cores equally by multithreading. But how can we do this ? Can the listening task of ports also be distributed ? I need an efficient algorithm for load balancing among threads. The data sent and receive rate of server is about 8.5MB/s. How can we improve this ? we are using gigabit LAN card. When the server only receive data from client it can receive data above 80MB/s. But when it both receives and sends data simultaneously it only manage upto 8.5MB/s.
I am at a university where my bandwidth is severely capped. I can start several other computers near me and download at the limited speed simultaneously. Is there any way for me to share the download between the computers to get the cumulative speed?

I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.
