SQL Server 2008 R2 Full-text search engine (FTS) is taking up too much resource (I/O & Memory) in my production server. (migrated from SQL server 2005).
I have been reading up on SQL Server FTS engine Internals and Enhancements and there was a suggestion on how to improve FTS performance under Performance Improvements section
Increase the page file size if applicable.
But it doesn't mention how much page file size should be increased by. Should it be adjusted thru trial & error? or is there a rule of thumb I can follow?
From here:
For example, if physical RAM is 8GB, then ideally you should allocate 24GB to VM.
You may be able to get away with less (1x-2x) but you'll need to perform some load testing to verify that.
