Hi Phil, I looked at the 3Com Gbit NICs, but I've had some performance problems with the 10/100's in the past. Not anything to do with Snort, but it kind of turned me off to the whole 3Com line. Terrible performance using them on some Win2k caching servers... Which of course probably wasn't the fault of the NIC... But I digress. =) I'll probably end up testing them in the lab regardless, thanks for the recommendation. Speaking of 3Com, didn't Nortel sell 3Com the Alteon NIC business when Nortel assimilated Alteon Web Systems? I looked on both the respective web sites and couldn't find anything about the deal, but I think I remember hearing this somewhere. The Alteon Gbit NICs were some of the best I've seen. It would be nice to still have a source to buy them if the technology is still being used to produce cards. Anywho, I'm looking at monitoring in the range of 200-300Mbits/sec, with 300Mbits/sec being the absolute max. Being a bit concerned about packet loss with that kind of data volume, I'm also looking at breaking the traffic up using TopLayer switches or Alteon 184s; an IDS load-balancing feature was included in the recently released code for the 184s. That would allow me to get around the limitations of one box monitoring a lot of traffic, but the costs would be significant to go with the preferred solution... That being to purchase a TopLayer switch. The plus side is I already have the 184s, and the extra boxes it would take to do the load-balancing, I'm just a bit hesitant to do it because of the newness of the load-balancing code. Thoughts?

But, another sot like myself in this business, has tested a few, and thinks the Intel might do a little better. But, he said if it's working for "you" (that would be me), then don't bother switching yet. What kind of gige rates are you talking? I think they will all fold at some point less than a gig. No problem at .2 gig. I could go through my archives and try and find some commentary, but I got to put in a concrete slab tomorrow, and I'm about ready to drop from operating an idiot stick all day!

I've searched on Google, as well as other resources, and can't really come up with anythingexcept peoplesharing their bad experiences doing so. =) I tend to lean towards Intel, as I've had good experiences in the past with their 10/100 cards, but I thought I'd check with ya'll to see what thecollectivecommunity opinion was.
