Tiffany, you are the second person who has claimed this. A Matt Kroll told me the same thing, but MS, Citrix and myself feel that isn't it. I put in a test box with 1 hard drive with no RAID controller and got better performance. Daniel J. Samaan=20 Senior Network/Security Engineer - CCSE, CCA, CCNA, MCSE dsamaan@xxxxxxxxxxxxxxxx -----Original Message----- From: Tiffany Ernest [mailto:tiernest@xxxxxxxxx]=20 Sent: Thursday, October 03, 2002 3:22 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: latency We had this problem but it was because of the read/write cache settings on our array controller (Compaq Smart Array 431). We had to upgrade to a controller that we could change the settings for the accelerator ratio (make it 50/50). After we made that change the latency went away. tiffany=20 --- Frank Monroe <Frank.Monroe@xxxxxxxxxxx> wrote: >=20 > The MS hotfixes and registry setting were applied.=20 > The Citrix hotfix was > not applied because I have the behavior even though > that feature is turned > off. >=20 > -----Original Message----- > From: Erik Gerard [mailto:GERARDE@xxxxxxx] > Sent: Thursday, October 03, 2002 4:15 PM > To: thin@xxxxxxxxxxxxx > Subject: [THIN] Re: latency >=20 >=20 >=20 > Did you try the two MS hotfixes and the necessary > Reg edit?
