if i transfer a big file, after about 20 seconds the IP stop to

anyone had the same experience?


Have you still got 2 CPUs defined? Use only one.

no Doug, it's not

it's all the afternoon that i'm running with just one CPU
and i've the stack ip that works completely randomly

(also see that with 2 cores i ftp at 8MB/sec
with one core at 4MB/sec it's not acceptable speed
so if my speed is limited to 4MB/sec i will not use virtual box at all)

i've seen before this kind of issues
in the past there were IRQ conflicts (on bare metal)



i've put up again the AMD PCNet-FAST III and as a "miracle" :)
the tcpip is back to work perfectly

1 core : 4,4MegaBytes/sec ftp datarate
2 cores: 7,4MegaBytes/sec ftp datarate

for my needs 4,4MB/sec is not acceptable, too much slow for a server
expecially when they have to bkup GB of data...

so the problem is not the multi core configuration
the problem is the intel pro 1000 virtual nic

maybe the drivers i've used E1000.OS2 and E1000_C.OS2

i'd use E1000B.OS2 (multimac32) but it's not compatible

any suggestion for the best driver to use in the guest VM for the Intel pro 1000?
