[cfaussie] Re: CFMX Spider on Reboot

[gary menzel]

FOR INFO......

There were a set of articles in the Cold Fusion Developers Journal that had batch files to pre-compile all the CFM code to the cached Java classes (to avoid the big hit when doing large updates).  I cannot remember which issues thought.

Secondly.... just wondering what was meant by "in the event of a server reboot" ?

The pages are compiled and cached in the webroot/WEB-INF/cfclasses directory.  A server reboot will not cause them to be compiled again.  The only way they will be made to recompile is if you change the file or delete the files from that directory.

In addition, the "tester" of the code would (should) generally be the first one to run the pages in the production environment (especially for a small number of pages).  So the performance hit will be experienced by people who are expecting it (overall).
