We've been looking for ways to improve performance with RH
and RSC. As part of the analysis, I used a performance monitor to
see what processes occurred while RH was running. Yikes!
Even when I am at rest in the project, a seemingly
endless parade of file accesses goes flying by. Thousands upon
thousands of them. I see this odd looping through files that are
associated with the templates, and an ongoing polling of all the
folders in the project. Once in a while, it will stop. Certain
activities seem to set the whole thing in motion again.
Has anybody looked at this? Is there a way to tame this
behavior to achieve better response time? At a casual glance, it
looks like RH7 restricts this behavior a little bit. Where RH6 was
doing its template-related looping more or less constantly, RH7 was
doing it about once a second. That's not enough to tame the beast,
It keeps on going even if I'm idle. (Not that I'm admitting
to being idle!) It's not entirely consistent, though. Sometimes it
stops and waits. I did see an interesting correlation where the
entries were just spinning by...until I closed the Single Source
Layouts pseudofolder. Then it stopped. Opening the folder again -
not *doing* anything, mind you, just opening the folder - started
the entries spinning by again. Same behavior with the stylesheet
folder. Not with the templates folder, interestingly enough.
Then RH had to mess with my neat theory by starting the
processes again without me opening a folder or touching anything.
I haven't established the pattern, but there sure seems to be
a lot going on.
