We are now 6 weeks into production with our cart, and are dealing with some significant performance issues.

The most notable are LONG delays getting to a product detail page, but in general, the site is sluggish, with frequent delays that can run up to a minute or two.

Our standard response when delays are prevalent is to clear cache and restart application, and aside from the long compile-time delay the first time a page is accessed, that seems to help, but within a day or two, performance is again poor.

We moved the site from a shared hosting account to a dedicated virtual server, shortly after implementing, to have better control over configuration. We have just increased available memory to the virtual server from 512mb to 1024mb, and that has helped a little.

Are there any specific configuration recommendations to improve performance? Or are there any performance improvement changes in the development pipeline?

Ours is a small site, with fewer than 200 products, and order traffic is on the order of 10-20 orders per day. This application is the only one implemented on the virtual server, so there is no outside impact to be worried about.

What version of dnn are you running I know there have been great performance improvements in the lastest versions of dnn 5.4. Regarding your server configuration 1gb of ram is not enough to run a dnn site. A web server running a dnn site should have 8gb of ram but at a minimum you should have 4gb of ram. Your probably experiencing alot of disk thrashing becuase of low memory.

Performance and tuning a dnn site or any application requires investigation into many items in your environment including:

  • Bandwidth throughput mb/s
  • Network - topology, devices, firewalls and switches
  • Hardware - CPU, RAM, disk
  • Software - Windows, SQL Server, IIS, DNN

Here are a couple good posts on dnn performance and tuning:
