Slow load times for Word add-in due to Fusion Logging
How I solved the much-discussed slow load time problem by using a solution not mentioned anywhere else

Hello everyone,
I just wanted to share the solution I found for my own slow-load-times problem.
I have an Add-In Express add-in for MS Word (2000 and up, installed for all users). The add-in would take around 8 seconds to load, sometimes more.
I read all the material on this issue, including http://www.add-in-express.com/forum/read.php?FID=5&TID=9921 and http://blogs.msdn.com/b/vsod/archive/2012/05/19/resolving-performance-issues-with-loading-office-add-ins-vsto-add-ins-or-shared-add-ins.aspx.
However, in my case, I was running a .Net 4.0 add-in, so CRL wasn't an issue (plus I disabled it just to check). There were no performance issues with the server, and no other add-ins or macros were being loaded.
And here is the solution to this problem: by trial and error, I found out that Fusion Logging, which was enabled on the server, had created many bloated logs that reached several hundreds of MB.
Once I deleted these logs (and still had Fusion Logging on), loading speed changed from more than 8 seconds, to less than 1.5 seconds.
I don't know why a bloated fusion log would cause this, but it did. I later disabled fusion logging altogether because it wasn't needed.
But just in case someone else comes across this problem, this is how I resolved it.

Cheers,
Ido Kalir
