Hi,

This may be a stretch to say this is an Exchange performance tip but it will speed up loading the Exchange Management Shell (EMS) so I’m going to post it anyway! :p. I’ve seen quite a few blog posts relating to this subject, too many to reference them all, but this one sums it up nicely (http://msexchangeteam.com/archive/2008/08/01/449426.aspx).

For me I just pasted this…

Set-Alias ngen @(
dir (join-path ${env:\windir} “Microsoft.NET\Framework64″) ngen.exe -recurse |
sort -descending lastwritetime
)[0].fullName
[appdomain]::currentdomain.getassemblies() | %{ngen $_.location}

… into notepad,
saved it as c:\temp\speedup.ps1,
loaded Windows PowerShell (Start à All Programs à Windows PowerShell 1.0 àWindows PowerShell),
cd \,
cd temp,
.\ speedup.ps1 <enter>

Script will run through in a few seconds and that’s it! J

Make note of what the link above says about the 32bit version of the .NetFramework!
