thanks God we use sata now, then you have no worry about optimizing the disk, because on sata disk the DMA is on by default and always on.

and the speed is depend to the drivers of the disk, so maybe you have to choose the right hardware for your server.

below is my tests, the best is from the test on intel xeon with intel motherboard (i dont know yet the other spec :)

A file with an extension of bz2 has been compressed with the bzip2 program. A bzip2 file can be 10-20% smaller than a gzip version of the same file. How can you extract it in Ubuntu?

First, install bzip2  in Ubuntu:

$ sudo apt-get install bzip2

How to Create .bz2 files in Ubuntu:

$ bzip2 test.txt  (where test.txt is the name of the file you wish to compress)

Today I've just read this news, how Windows beat Apple and Ubuntu:

It turns out that Microsoft wins this one hands down. Their Windows software update was available 100% of the time.

Apple had a respectable 99.9% uptime for its software update. It was only unavailable a total of 2 hours and 34 minutes.
