Sure, actually if we find some issues with Orchard itself, it will be part of the next release.

Have you tried installing "new relic" to identify bottleneck? It's a great tool and I think you can get a trial but you do have to install it on your server which might no work for production.

To keep this email short I am not going to include all of the technical details, tell me what you need from me and I will provide it. We have encountered two problems when importing the posts: 1) the more posts that we import (via the orchard command line and a bespoke import module) the fewer posts we get to import before the session times out, I have been able to circumvent the nHibernate session time-out by encapsulating the import of each post in a new TransactionScope with TransactionScopeOption.Suppress however I then run into a .NET remoting time-out. 2) we experience a significant slow down of the whole site, but particularly the blogs dashboard which more often than not was timing out, this appears to be the result of currently unused enumeration of all comments in a blog. We have implemented the following to improve performance: * Warmup - improved start-up times * Set Trust to Full - no obvious effect * Added Index for Orchard_Framework_ContentItemVersionRecord column ContentItemRecord_Id - most frequently run queries, small improvement * Added index for Orchard_Indexing_IndexingTaskRecord column ContentItemRecord_Id - frequently run and expensive - no obvious effect to page load times * Set Resource Debug Mode to Disable - no obvious effect to page load times * Installed Cache and Database Caching modules - significant effect although still slow The biggest improvement was disabling Search and Indexing, so I suspect the indexing service is causing the majority of the problem, search and indexing however are required so that is not an acceptable fix. I have time at the end of the week to focus on performance, profiling and optimization if anyone has some specific areas to look at I would be more than pleased to take on suggestions or advice.
