hi :
I did this test on the two machines...
Linux 1.2.5 :
P90, 2940, AIR54CEP, 16MB RAM, 1G SCSI (slower than next HD)
FreeBSD 0412-SNAP :
P90, 2940, AIR54CEP, 32MB RAM, 1G SCSI
Only RAMs and HDs are different...
Though the HD on linux is 1/3 speed of the one on FreeBSD base on iozone test,
but I found that Linux's disk-io is faster and more "quiet" than freebsd ...
When un-tar the gcc-2.6.3, linux use almost the same time as freebsd,
and when delete the tree, linux is 3 times faster than freebsd...
(the HD on linux is 1/3 speed of the one on FreeBSD base on iozone !!)
I guess maybe Linux will allocate as much memory as it can to be buffer.
Especially when the memory is more than 32mb or 64mb, linux will be much
more faster than freebsd on the same machine...
Anyway, I still love FreeBSD and hope it will be really fast someday !!
:-)
