I've seen slowdowns with both UP and SMP -current machines under load. Putting this in my config file fixes things: options NO_SCHEDULE_MODS Andreas mentioned that he didn't see the slowdown until he cranked up the two RSA crack processes. So I think it's probably the same problem.. John knows about it, and said that he would work on a fix. Ken -- Kenneth Merry ken@plutotech.com
