next in thread | raw e-mail | index | archive | help
I'm using FreeBSD now since 2.0.x and I love it...
But now I'm experimenting with samba and the performance
drop is so big that I think I forget something...
WIthout samba the 100mbit fxp0 link crossover was
almost maximal used during ftp...
With samba it drops to about 80kB/s
I included some comfiguration info underneath..
Any advice is appreciated, please cc to me!
Greetz,
