There are some ways to configure cron to run a job 30 minutes after startup. Jenkins does that by hashing the function and using H/30 * * * * for example. It could also be a thread sleeping for 30 minutes and spawning a silent cpu killer process. Some ideas there : Did you try htop as root? Some processes may be invisible, I've seen this on Debian ...

That's a 10 year old single core CPU. You're talking about Ubuntu with the Unity desktop? That's designed for modern hardware. It needs the same sort of power that Windows 7 or 8 does. You read all kinds of stuff about Linux being great for old computers, and it is, but the part they don't tell you is that Linux technically is just the kernel. That ...

Check the top and see if you can reduce some of unused applications. Also a bug has been reported w.r.t to graphics https://bugs.launchpad.net/ubuntu/+source/unity-greeter/+bug/1292467

I had the same problem and the reason was a link to a network drive folder which was not working anymore. After removing it everything starts loading instantly.

I have a hunch, that actually the applications are stopped roughly around the same time, however the windows itself are destroyed at a different time. These are minor programming issues - if this is the case.

I installed Linux Mint 17 yesterday and noticed this evening that kworker was consuming 100% of one of 4 cpus. I ran the above check, but did not find anything other than 0 for the interrupts. While examining the services that I normally have running, I noticed that shutting down the nfs server dropped the kworker thread back to zilch. A restart of the nfs ...

I made a similar post and no one has answered it yet. I have an i7 and a very good nvidia graphics so hardware isn't the issue. From what I can gather its the crappy kernel version they chose for 14.04. Bottom line: Use 12.04.05LTS till end of life. I switched back after the tremendous lag and slow loading from 14.04 and 12.04 hasn't let me down once. Not ...

System do not know what is "too much ram" or "too slow" or "important applications". You must manually setup this limits for your program. See topics: oom-killer, renice.

Did you take a look at the Wine App DB entry of League of Legends? There's a section with tips to increase performance. Otherwise there are very few things you can do: use a current proprietary graphics adapter driver, try a newer (or sometimes older) Wine version, try a different desktop compositor or none at all.

NTFS vs EXT4 will not gain you much if any better performance, it will allow you to use extra chars with files/folders naming and much bigger single file sizes.. read link below. EXT4 vs NTFS (A Bit Old But Still Stands) Overheating on the other hand will effect the computer performance, so a clean heat sink will give you more improvement than a dirty one. ...

If I convert all drive to ext4 will this improve the performance? Are the NTFS partitions mounted? But even then I doubt that it'll improve performance. cleaning the laptop fan and dust make any change in performance ? Perhaps if it throttles the CPU due to overheating but most probably: No. Conclusion Chances are very high that your laptop is ...

creating the hundreds of thousands of files might have created a lot of filesystem extents that do not necessarily get removed when the files are removed. Get a "fragmentation score" with: sudo e4defrag -c ~/ and if the score is bad (higher than 50, say), use the same command without the '-c' flag to defragment the filesystem.

You can install preload by sudo apt-get install preload preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times. Tweak by compizconfig-settings-manager like : Disable ...

I run my main laptop on solar power all the day and have limited power. Reducing CPU clock speed helps the most in my experience. You can install CPUfreq tool, and set a Powersave option or manually set the lowest clock speed. sudo apt-get update && sudo apt-get install indicator-cpufreq Also switching off Wifi from device physical on/off switch ...

Changing the HDD to and SSD would indeed give you more battery life, but probably not more than 15-30 minutes. Ubuntu is not really more power saving than windows, but if you run a desktop environment that is low on processes and not too shiny, you can probably get some more minutes out of it. I would suggest you try it out from a Live DVD/USB. See how long ...

You weren't particularly clear on your hardware setup, but a P4 with a GeForce2 (I think that's what the NV32 means here) is a thirteen year-old computer system. First of all, while that's officially above the minimum specs for Ubuntu, it's terribly slow compared even to a 2007 computer. You need to accept that fact. The graphics card is quite old, and ...
