Performance difference between if(!-e) and try_files?

[Peter Portante]

FWIW, we ran with "if (!-e...)" for about 2.5 years, filling up our
error.log files with useless messages in the operation of that scheme. It
help hide a number of problems that were not see because the volume of
messages was so high.

By using try_files, we were able to substantially clean up our
implementation, and find and fix a number of problems.

We have not measured performance with this change, but just the fact that
you don't make a log file entry in the error.log is probably a win in and of
itself, I would think.
