"FX" is IMO too generic - see http://mail.opensolaris.org/pipermail/perf-discuss/2007-June/001727.html (part of the issue is to have some kind of "tag" which says "batch job". Think about situations where admins of larger servers like to have a "hint" what the process is doing in the next hours or whether it's safe to nail it down via "pbind"&co. etc. ...). ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
