------- Comment #3 from enrique_pinos@yahoo.es  2008-09-24 07:11 -------
> 500 MB/s on disk reads?! That's totally wrong expectaion

For my personal computer (Pentium IV)

hdparm -Tt /dev/hda

/dev/hda:
 Timing cached reads:   1500 MB in  2.00 seconds = 749.31 MB/sec
 Timing buffered disk reads:  184 MB in  3.01 seconds =  61.14 MB/sec

Server I'm using its athlon 1800MHz and I got same performance as previous
server I got (k6-II @ 450MHz) I found server slow in transfers and high CPU
usage (and k6-II never warnning me for hardware limits :S) This is the reason
I'm in doubt.
Upgrading server didn't increase transfers between my PC and my server, in my
local network :(
Thanks for replies.
