3.0 out of 5 stars Works but you need a fast PC to get full Gb speeds, 16 May 2012

Verified Purchase(What is this?)
This review is from: TP-Link TG-3468 Gigabit PCI Express Network Adapter (Personal Computers)
This card does indeed work well if you have no intention of going for full gigabit speeds and performance without good fast CPU.

The issue is that this card only has limited support for Jumbo Frames, Judging from the Drivers it supports 2k,3k and 4k. though i did try 3k and 4k frames gave me very slow throughput less than 2mb/s so they obviously wern't working very well.
The regular MTU of 1500 works ok though but it does mean that you will get alot of cpu usage to get anywhere near full gigabit speeds. perfectly fine for that extra speed above 100mbit/s you might encounter with ever faster internet connections.
It's a shame because most other brands if this card using the same realtek 8168 chipset support and work well with at least 7k frames( like my old PCI card this ones is replacing), most work with 9k frames, which this card does not. This card also lacks modern Ethernet power saving features too.

MY old PCI card I was able to get a solid 100+MB/s accoss the network, now not so solid 50-80MB/s.

It also works fine in Debian but only with a standard 1500 MTU too which is handy yet disappointing because there is currently no working driver for the Atheros 8151 onboard lan chip on many new motherboards (including mine) with the current (at time of writhing) latest stable Debian squeese kernal. Still miles better than 100mbit.

The bottom line is, If you know what Jumbo Frames are and want to use them this card is not for you. If you have a good PC from the last 5 years you probably have something better onboard anyway unless that failed or doesn't work with your Linux distribution.

I just bought the card from Amazon and installed the latest drivers from the T-link website. These do support 9KB MTU. The hardware is V2.1, if that's relevant.
