Why does my Sitecore website keep recycling?

2014-03-05

For a week now one of our clients websites have had very poor performance.

It seem that the application pool was recycle all the time.

 

We have tried everything until I notices this setting

 

<setting name="Caching.DisableCacheSizeLimits" value="false" />

 

We’re running a 64-bit application where this is not needed, since it has a larger memory space available.

Flipping this switch seems to have solved the problem.
