I believe this is an issue with windows 7 64 bit. There seems to be a lot of context switching involved with running a 32bit app under Windows7 64bit using Wow64: http://en.wikipedia.org/wiki/WoW64 A forum post relating to 32bit performance on this platform: http://www.w7forums.com/windows-7-64-bit-vs-32-bit-t484.html Rui Amaral Database Administrator ITS - SSG TD Bank Financial Group 220 Bay St., 11th Floor Toronto, ON, CA, M5K1A2 (bb) (647) 204-9106 ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Andrew Kerber Sent: Monday, April 18, 2011 4:47 PM To: ORACLE-L Subject: A good xwin server? Has anyone found a reasonably fast xwindows server? On my 32 bit windows xp virtual machine I can get the oui to work reasonably fast, even connecting to a data center 4 states away to do an install using putty and cygwin. But when I run the OUI (or asmca or dbca for that matter) directly on my desktop,which is windows 7 64 bit, and connecting initially with putty, its just dog slow on cygwin or xming. Is there a faster xserver out there for windows 64? Or maybe the problem is with windows 7 64 bit? -- Andrew W. Kerber 'If at first you dont succeed, dont take up skydiving.'
