Thanks Eliezer. You are right, esxi timing is all sorts of wonky, and as few a cores with as much speed dedicated as possible seems to be the best answer I have found. I might actually rebuild this sucker on a raw linux box and ditch the esxi host shindig, just adds bloat when the only virtual machine you're running is squid anyway. There was a case made for multiple systems on this thing, a while ago, but that case is getting weak and we have other machines to do that now. > -----Original Message----- > From: Eliezer Croitoru [mailto:eliezer@xxxxxxxxxxxx] > Sent: Wednesday, February 17, 2016 8:44 AM > To: Jester Purtteman <jester@xxxxxxxxxxx>; squid-users@lists.squid- > cache.org > Subject: Re: Rock datastore, CFLAGS and a crash that (may be) > known > > So after reading the whole thread from top to bottom: > Since it's an ESXi version 6.0 with an Ubuntu 14.04 guest I would choose > another approach! > You do not use any SSL related settings and it's a simple proxy(from the squid > -v output) so I would ask "did you tried to rebuild any deb file?" > There might be some benefits from a special flag or more but from my > experience with such VMs it would be very little in most cases.(I do not have > tons of experience...)
