We've also run into the same problem with very poor TCP performance with 2.2.2-ac3 yesterday. Here's the config for my machine:
RedHat 5.2 installation + relevant updates for 2.2.x kernel Pentium 200MMX with 64M ram Linux 2.2.2-ac3 egcs 1.1.1
We looked at performance in two categories: transferring small files (256-512 bytes) and large files (ranging from a couple of k to 128k). For small files, the 2.2 kernel was a touch slower than 2.0.36 (approx. 5%), but the real shocker was the performance for the large files, where the 2.2 kernel was about 12x slower than 2.0.36.
For reference purposes, the files were being served up by a light-weight multi-threaded web server we wrote/use internally. The client was running NT4 and using a program that cycled repeatedly through requests for the particular pages. All pages were already loaded in the server's cache before running the benchmarks so that the filesystem wouldn't come into play.
If there's any further information I could provide that'd help track this problem down, please let me know. It's a bit of a show stopper for our purposes.
