When "Report Execution Times" is enabled for debugging in "summary" mode, the Debugging output time becomes lengthy with a moderate number of templates and function calls.  We are experiencing, with 100+ lines in the "Execution Times" section, load times of ~7.5 seconds.

Disabling "Report Execution Times', result in the debugging output almost immediately.

Occurs in dockable and classic output format.

Switching to "Tree" for the output mode of the execution times, results in an output time ~2.5 seconds, which is better than previous version of ColdFusion.

Have replicated this on several of our fresh installs of ColdFusion 10.

Comments:

Files are on a network share. Interestingly enough enabling "Trusted cache" in the Caching section of the admin results in fast loading. From the debug output 160 lines reported, prior to trusted cache: 1104 ms TOTAL EXECUTION TIME Debugging Time: 7376 ms post trusted cache enabled: 1104 ms TOTAL EXECUTION TIME Debugging Time: 127 ms This is less than ideal, as we would like to enable debugging in test environment without having trusted cache enabled.

Can you share me the files which is resulting in Slow Loading Debug Output so that we can investigate more easily? (Comment added from ex-user id:kamaiya)

I will not be able to provide the source code where this is occurring. Even if we could it would be a bit difficult as we see this occur where there are a large number of files involved through several cfc function calls. One example is our legacy in-house built CRM, where we can included anywhere from 10-20 templates and 50-100 method calls on any given page. We only experience this in that scenario, a handful of templates does not seem to be an issue. I could include the actual full debugging output if this would be helpful.

Another update, I just went to our staging servers and tried to reproduce this to get an example of the detailed debugging and can no longer reproduce the issue, even between service restarts. I guess feel free to close this issue as you see fit.

This is likely to be caused by expandPath() struggling when there are custom tag paths. See https://bugbase.adobe.com/index.cfm?event=bug&id=CF-3279677
