You CPU is slow. A score of 760 for a dual core CPU is bad. If you take a look at the single-core performance for that CPU on the site it's on par with a good Pentium III. The GPU should be good enough for YouTube but together with the CPU it could be not enough. I can watch 760p YouTube in HTML5 on a Pentium M with a much slower AMD GPU. Be sure to have ...

I had a very significant gain using sort -n, which requires numeric values (float or integer) in all selected columns, without scientific notation. Another possibility that might bring a great improvement in your process is to use the memory mapped folder /dev/shm to deal with intermediary files.

For what it's worth, I recently went from the standard kernel in Ubunto 3.0.16 to the low latency kernel and the change to my desktop performance was phenomenal. It took some doing because the Nvidia driver included in the Ubuntu distribution would not load with the low-latency kernel however the exact same driver version from Nvidia's website worked fine. ...

Its reasonable to expect PlayOnLinux to be a little heavier than native. PlayOnLinux relies on wine, which brings in a whole layer of virtualization overhead. Steam on the otherhand is more of a grab-bag of some native games and some wine-wrappered games, so some will run smoother than others, depending on who/how it was ported. Additionally, the ...

Obnam's default configuration (as of 2015-02-08) does not work well for backing up directories with a large number of small files. I had exactly the same problem as mentioned above. The solution for me was to add --lru-size=8192 --upload-queue-size=8192 to the command line. This solved the problem and turned a frustrated into a very happy Obnam user. (I ...

I would use perl, it is faster and more efficient for this than find + rm 0,30 * * * * cd /var/www/magento/var/session && /usr/bin/perl -e 'for(<sess_*>){((stat)[9]<(unlink))}' Deleting my log directory with over 500,000 logs in it daily clears it out in under ~6 minutes.

If the only thing in that directory is sess_* files, you can just leave out the -name 'sess_*', and find will traverse through anyway. Test what it would match by removing the -exec part. $ /usr/bin/find /var/www/magento/var/session -type f -mtime +1 Then for the cron job, 0,30 * * * * /usr/bin/find /var/www/magento/var/session -type f -mtime +1 -exec rm ...

Don't bother exec'ing rm at all, find can handle it: 0,30 * * * * /usr/bin/find /var/www/magento/var/session -name 'sess_*' -type f -mtime +1 -delete

It may be slightly different in Solaris, but based on the Illumos source here, it looks like the value first displayed is since the process started and updates after that are since the last displayed value. The display updates every 5 seconds by default, but that can be specified.

I don't know about the ILM systems, but what you're asking for seems to known as a Single System Image cluster. There have been multiple research Operating Systems, over the years, which attempted to implement this, with varying degrees of success. Plan 9 is probably the best known candidate there, but it's not Ubuntu. The Wikipedia link has more details, ...
