slow write performance with Gigabit
 

hi,

I have one Linux Samba server ( FC3 + 1024 mb + AMD64 + Gigabit Ethernet) and I have another installed WinXP PC with Gigabit Ethernet.
I configured 512MB ramdisk on linux and WinXP PC.


When i copy winXp ramdisk to FC3 Ramdisk(Samba Share) for 456MB file; 43 sec ( 10.8 KB/Sec)

When i copy FC3 Ramdisk to WinXP Ramdisk 19 Sec ( 24,6 KB/Sec)

Why Linux write performance is low? (or samba write performance ?)

Thanks

What DMA level is your hard drive(s) using on the linux box? hdparm -i /dev/hda

Which filesystem are you using ext3?

for first question; I'm trying copy, between ramdisk to ramdisk, but my /hda is using udma5
for second question; filesystem is XFS.

and, FTP copy results; 107 mbit for writing Linux ,225 mbit for reading from Linux ,
