Hello listmates, As some of you may know we have been having a really bad problem with Realtek Semiconductor Co., Ltd. RTL-8169 cards. See here for details: http://forum.nginx.org/read.php?24,140124,140224 So now my question is, what PCI 1 Gbit/s Ethernet adapters should I use under CentOS? If you have had a consistent positive experience with any particular chipset/brand please speak up. Thanks. Boris.

That's what we use here w/o any issues; however, there are some Intel NICs that are *not* able to handle Jumbo Frames due to an internal design glitch. HTH, Timo> Thanks. > > Boris.

No need to mess with any Winnic(which is what most are). Broadcom is another good one.

I wouldn't hesitate to buy either but given a choice I'd go for intel (since I do think the few hickups we've had, more often than not, struck the broadcoms). For completeness (since many previous posts have touched on this), we don't use jumbo frames since we have no problem reaching wirespeed with normal 1500 frames. /Peter -------------- next part -------------- A non-text attachment was scrubbed...

Its use produces less overhead and in general less CPU utilization. Your network will see less trafic and your CPUs will be free to do other work.
