Back when I was running RTO, ARGGIS was the single application that used the most amount of virtual memory per instance on a Citrix server. It also benefited the most from the memory optimizations in TScale, and will benefit in a similar manner from the memory optimizations that are in CPS 4 (since they are the same memory optimizations). So, after you install ARCGIS, remember to either buy TScale, or check the box in CPS 4 Bernd Harzog Vice President and General Manager ProactiveWatch www.proactivewatch.com bharzog@xxxxxxxxxxxxxxxxxx 770-475-4249 -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Justin Martin Sent: Thursday, February 15, 2007 12:11 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] ARCGIS in a Citrix Environment Anyone running this is a Citrix environment?
