is your use of memcached hiding possible connection exhaustion issues?
would your memcached stuff help with london's problem?
Even when memcached is in place, I still connect to the database, even
when all the data is loaded from cache. (That's a bug, but not one I
care about). However, I have my database set up to allow max connections
of twice the number of apache threads I have, and OpenGuides only
connects once per page as far as I remember -- I've done some looking at
this -- so I don't think it'd be a problem...
However, I'm using MySQL, and I know you're not. It's possible that the
W::T Store module for Postgres doesn't do closing and MySQL does?
I can't tell whether memcached would help: it would depend on whether
there is free memory on the box, and whether the load is from getting
the data or from styling it. In general, the latter is generally true,
but someone with access to the box might be better suited to determine
In general, mod_perl has helped much much much more with performance
than memcached has, especially on the single-node case (rather than
category listings or the ilke).
