My desktop is a 3GHz single Intel Pentium >4 processor with 512MB RAM. I have noted by desktop >response wise sched_4bsd is better, ie. the desktop is >more responsive. >It just noted today the version of the sched_ule.c on >RELENG_7 is 1.214.2.2 dated 2007/12/20 and the current >version on the CVS is 1.240 dated 2008/04/04. >Since the FreeBSD 7.1 is planned to be released with >sched_ule by default, why don't you guys sync the >sched_ule.c with current so that more users like me >who run FreeBSD 7.X (RELENG_7) can give more feedback? >Kind regards >Unga The version you mentioned is in CURRENT (8.0) and proberly is not compatible with RELENG_7 at the moment. There have been a lot of changes to the scheduling and other stuff commited by jeff, read jeff's techjournal! I recall also in the mailing list that not all of those changes are being commited to RELENG_7 Regards, Johan Hendriks Double L Automatisering
