I'm replaying to myself because i have found out the solution. I have 
two bge adapters, fxp and xl.
If i'm moving all vlans (one or two or three or all 30) to fxp or xl - 
everything working just properly. No packet looses. But with bge - 40% 
of packets being lost.
Is it driver/os trouble or just my adapters should be changed?
I'll try to do the same tests on my notebook (dell) that have bge 
adapter also, but not now :)

Best regards,
Anton
