I remember having bad times in the far past with intel NIC's on RedHat 7 that used the e100 driver, back then we've just solved those problems by using only 3com NICs that worked natively fine with linux. I'd think nowadays those problems were over! I guess not... Anyway, this is getting too off-topic, since it has nothing to do with Cisco devices. Trying a different NIC, vanilla kernels or a different linux distro is definitely the way to go. Ziv

We've had a lot of problems with this issue. transatlantic speeds were faster on FE than on GE. Local speeds were great. It is indeed a bug in the kernel driver. After an upgrade to latest vanilla the problems are gone. Im not sure if anyone has created a rpm for a fix.
