Hi

I have a windows 2003EE server running in VB 2.2. I have the 100mb interface attached to the machine, this is attached to the hosts 1G network card. I try to do overnight backups of files from windows (I mount a smb share and rsync the files off), what I am noticing is my cpu usage spikes and I seems to get very bad performance, I start to get cifs fails and time outs.

Should I change the virtual network interface to the 1G one or should I look at something else. this is running on a amd64 debian 2.6.26 kernel. I am using 2.6.26 because I need the zaptel drivers and they are not compiling under 2.6.29 (yet)

THanks

I would suggest the IntelPRO/1000 group for your virtual adapter on a Windows server. Just do yourself a favor and get the drivers first in case they are not on you Windows install. Drop them in a share or in a folder on the system.

Any particular reason why ? Work better with VB work faster than the 10/100 Nic (I am presuming just because it says 1G doesn't mean it actually performs to 1Gb/s speed)

Well the intel series is easier to emulate so your host uses less cpu.

Cool that works for me
