Additional SMB Tweaks

Tuesday, 25 September 2007 by Michel Roth

Fileserving in Terminal Server / Citrix environments is pushing Windows to its limits. I've written about the challenges that you face in dealing with fileserving in Terminal Server / Citrix environments before. It takes some tuning to make sure that you get decent performance out of your Terminal / Citrix servers and associated file servers. The registry tweaks you can do to get maximum performance out of your fileserving infrastructure in Windows environments are numerous. I have some tweaks that you can use in my LanManserver and LanManworkstation adm templates in Thincompting.net's download section. Login Consultants' True Control Templates also has some of these settings and other well known registry performance tweaks as well.

Today the Windows Performance Team blogged about some additional registry tweaks you can do the limit the SMB ("the filesharing protocol") traffic that Windows explorer generates. The registry values Windows Performance Team talks about are:
