Orchard v1.6.0.0 Performance Issue / Admin Page

Topics: Troubleshooting
Aug 7, 2013 at 7:49 PM
I am currently running an Orchard CMS site on a web hosting platform. The version is The website, including the admin page, worked well in a development environment. Once the site was transferred to the host's webservers, we found that when accessing the admin panel, the main site performance slowed to a crawl.

The site is configured with 300 MB of RAM and additional CPU resources have been added as well. The site runs at around 250 MB of RAM. However, when we login to the admin page and perform any navigation, the main site becomes nonresponsive. A test with the web hosting provider in which we added RAM to the site while logged in to the admin panel showed the site continuing to consume RAM up to over 900 MB. The main site was still non functional until we logged out of the admin panel.

A web debug test showed errors such as below when using the admin panel:

Attach a memory profiler to see what module is responsible for it.
