If Trusted Cached is enabled, CF does not even check the last modified date on a file to see whether it needs to be compiled, it just uses the .class already loaded into memory. That can be quite a big speed up. The downside is: yes, you need to uncheck it and hit any changed files and then check it again to pick up those changes. > Java and JVM Settings > Max Memory Size: ---- what's a good max value > if > there's say 1024MB RAM on the server? Leave enough for your O/S to run (plus any other additional applications) but otherwise crank it up. You can also tweak performance by specifying additional JVM arguments (min heap, max perm size etc etc) - refer to JRun docs for tuning guidelines. See also the CFMX performance tech notes on the site which mention min/max thread settings etc. Most of all: load test your application and see what impact changing each setting has. The optimal configuration will be different for every application.
