[rum-discuss] Performance

[Michael Brickenstein]

Hi!

Since a long time, I suspect, that the number of register that routes
might be a problem for the RUM performance. My Profiler seems to
indicate, that rum, spents 40%
of its time in
route.py:265(makeregexp) <-
27560 calls (for 5 web requests).
and the underlying functions

Can anyone comment the following numbers please?

Is that indeed much? Might that be the reason for bad performance?

for (k,v) in app_globals.admin_app.router.mapper.maxkeys.iteritems():
print len(v)
573
332

Cheers,
Michael

Hi!
While trying to upgrade to routes 1.12 (which has some new regex
builder feature),
I got the following stacktrace,

I guess, that's also about our many routes...:

Cheers,
Michael

Hi!
I am working on a largely improved version.
Since still some tests fail, I uploaded it only to bitbucket and not
into the official
rum repository.
