[Vserver] best timer freq to use?
also, have the vserver systems been tuned around a certain timer frequency? 100? or 1000? or in between somewhere? for best efficiency still allowing remote terminal responsiveness under extremely heavy loads? -- Chuck ___ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
