Hey,

 

I have some links that you could be interested on them:

http://www.intel.com/support/network/sb/cs-009209.htm

 

All of them talks about the interrupts.

 

So, what do you think should i do with my e1000? What do you think could be the best board for sites as 8.000 customers? My problem is exact these lots of interruptions.

 

Thank you in advance!
