I'm having some performance issues on a site which uses CropUp quite heavily. The site has a license for ImageResizing and the Cache bundle. The server administrator has run some tracing to try and locate the source of some of the issues and one of the biggest bottlenecks appears to be the CropUpUrls Module. See an extract of the trace below, this is one of many:
The more concurrent users/requests the worse this problem gets and can result in unacceptably slow page requests.
Any ideas why this might be happening? The site is running Umbraco 4.11.10.
Have you tried disabling CropUp Clean Urls? (i.e. comment out <add name="CropUpUrls" type="Eksponent.CropUp.Plugins.CleanUrls" /> from <httpModules> and <modules runAllManagedModulesForAllRequests="true"> sections of web.config)? CropUp should still work but it will bypass the HTTPHandler that does the URL rewriting. I've done this before to get client-side image caching to work.
No idea if this will fix the performance bottleneck but it's worth a try :)

Hey Simon,

Thanks Dan, will give that a try and let you know.
That did actually help the situation. Happy to sacrifice the clean urls for the performance benefit for now.
Cheers, Dan!
