Subject: deploying pyramid apps on heroku
Print | Individual message | Show original | Report this message | Find messages by this author

Hi, I am testing heroku as a platform to deploy pyramid apps.

I notice an extremely low performance (2 seconds to provide a page) and I
am wondering what can be the reason. I am not using sqlalchemy, I have my
custom sql methods with psycopg2 and that have proven on other platforms to
be fast.

I still suspect that the database is the bottleneck, particularly with
establishing the connection. Do you have experience with heroku? Are you
facing the same problem? And how do you solve it? I am thinking about using
a persistent connection, but I don't know how to do it...

I've deployed a pyramid app to Heroku and used one of their MongoDB
providers with no lag issue whatsoever. If you suspect the issue is with
the database provider I'd contact them directly or you can try asking
Heroku.

I'd recommend you log the time it takes for your pyramid views to respond,
as well as the model functions you call to make DB access to try to narrow
down where the bottleneck comes from.

Well, after making some tests and by using the debug toolbar, I was able to
find that the problem was establishing connections to the db. Thus I
inserted a mechanism for connection pooling and I was able to get a 16x
speed increase.
