Hmm, since which kernel version, out of interest? The reason I ask is that I found it necessary to set SHMMAX for an AMD64 Sarge machine with 16GB RAM running as a PostgreSQL database server and improved performance significantly as a result. For compatability reasons with the hardware, I couldn't use the most recent kernel: it's running 2.6.12. Dave. -- Please don't CC me on list messages! ...
