Demon ran Harvest ) for a (short) while, but seem to have reverted to the CERN caching ) server. Dunno why - I know CERN is slower, but I beleieve there are some ) stability porblems with Harvest under heavy load. I don't know ) if CERN behaves that way - it's process model is very different from ) Harvest. both *can* behave that way, and both can be configured *not* to. CERN required OODLES of RAM on the server as each 'document' [text, picture, gif, etc] requires a separate PROCESS. Harvest uses a non-blocking design with a single process, and is possibly better for small servers.
