I have found that the Lotus Notes (Domino server) swaps excessively even when there is plenty of free RAM. My first experience was running it on Solaris 6 which does not swap at all when there is over X free RAM. Immediately the Domino server put more stuff into swap than into RAM. I told the Notes admin this was a problem and Lotus should have a recommended setting but he blew me off. I later found a doc from Lotus that recommended tuning kernel memory settings on Solaris. Now I have headed a performance project for all servers and see this problem on the W2K servers (only ones running Lotus). Again I approach the Lotus admin with no results. I’m wondering if anyone has seen this and has a way to fix it. I have work arounds that do work such as nulling the swap file or putting swap on RAMDISK, but there must be a clean, Lotus approved approach. The notes admin still refuses to contact Lotus on this issue. The only guides I see online suggest sizing for RAM and swap, but that doesn’t help tune how swap is utilized.
