Hi, I'm rather interested in the outcome of this on or off the list; but I suspect there will be other people on the list who are interested - please keep posting to the list :-)
I think we have very similar HW. We have a dual CPU (1.4G PIII) LPr2000 netserver with 10k and 15k drives. We normally sit around < 5% cpu so it seems to be something about your config, probably not your HW. Our box also does internal http, mail, dns, fax, lpd, ldap etc. Can I suggest you run top and see what seems to be using CPU time? Does %CPU in the process list include sys time? I think it does, if so, it will help you get an idea of what is contributing to the 60% sys time (even if top doesn't include sys then it is likely to be showing culprits anyhow). Do you run anything else on this machine (eg oracle)? :-) Perhaps posting ps axf and a copy of a top page might help. Your LDAP backend... is it getting busy? Are the relevant things indexed? I'd upgrade your kernel to the last RH7.3 errata (2.4.18-10?). You will likely get locking issues (discussed on samba-technical show stopper) if you are using ldap sam, I patched the samba 2.2.5 rawhide rpm. I'll send that in a separate email to you. Good luck.
