i remember when i first started using freebsd about 2 months ago, the first kernel i built, i did the ULE (at some articles recommendataion). but, ive not done it since. i guess i have been noticing a bit of lag on my system (amd 1800mhz 512rdram, u160 scsi raid0), but nothing unacceptable. however, since i didnt have a problem with my first kernel that i did, and your positive response, i decided to go ahead and change out the specified scheduler in my kernconf, and let 'er rip. is your system a desktop? were your prevously running the same desktop configuration on the same box, with the 4BSD? is the ULE scheduler suited for a server setup as well (my server is also SMP), or is this something that should be kept to a desktop? thanks, jonathan horne On Sunday 07 May 2006 04:43, Duane Whitty wrote: > Hi, > > I decided to give the ULE scheduler a try a while ago (April 28). > when I last built 6-STABLE > > Anyhow it seems great.
