Are there any known issues with your software and the aspnet worker process? (IIS 6)
Precompiling solves a different problem. See below. I (not a BV Software employee) am not aware of any unique issues between BVC5 and the worker process. However there are several well-known techniques for tuning the performance of any ASP.NET application. Here are a few tips...
If the first time you load any page of the site takes a long time (but then every page loads quickly), then use a ping service (SmarterPing, PingDom, ...) to ping any one page of your site to keep the process active.
If the first time you load any page takes a long time (even if another page in the site has already been loaded), then use a ping service to ping the slowest pages *and* precompile the entire site.
If certain pages take a long time to load every time, then you will need to determine if the page takes a long time to calculate (i.e. retrieving data) or a long time to render. If it takes a long time to calculate then rewrite the logic so it does not take as long. If it takes a long time to render, then reduce the amount of HTML.
The 3 most effective ways to reduce the HTML are:
1. Reduce the number or size of the images on the page.
2. Reduce the size of the tables in the page.
3. Reduce the size of the Viewstate.
