Is diskbased MOO going to be part of the next release?
No. No diskbased version of MOO is planned. (The following from a post to MOO-Cows from Roger Crew ( rfc@microsoft.com).) Since most machines these days use virtual memory and disk I/O caches, the line between “running off the disk” and “running entirely in RAM” is rather severely blurred. It is the fundamental nature of virtual memory that, once you request more memory than you physically have, you are, to some extent, running off the disk whether you like it or (more likely) not. Conversely, a program that “runs entirely off the disk” may yet be running mostly in memory if its pattern of disk accesses is suffiently I/O-cache-friendly (i.e., not trying to touch so much of the disk at once that it blows out the cache). The real issues as I see them are: (1) performance That is, what performance win is to be had by having the server take more explicit control over the disk One would think that since the server has some concept of how often various objects/slots are used, it could implem
