Hi there,
I've been doing quite a bit of profiling on my app over the last few
days ... and well on my dev machine it's working a treat. (However I
do notice that using the displayGroup - even with using
ERXBatchingDisplayGroup + ERXDatabaseDataSource that there's a few
extra round-trips to the db that needn't be... but that's another
optimisation to come).
However, when I deploy my app to our intranet, the list pages are
seriously slow (even moving between batches). I'm connecting the
same database on both machines (mine connects remotely obviously)
but there's some serious bottleneck somewhere that I can't figure
out. Locally it's great, deployed is sluggish as anything.
Unfortunately I can't find a profiler for FreeBSD (the platform of
our deployment servers) ... so I'm wondering if anyone has any other
ideas?
Are you using the same version of the JDBC drivers?
Is it also slow if you use direct connect?
Have you checked Safari's "Inspect Element -> Network" to see where
the browser's time is being spent?
Is the JVM being allocated sufficient memory?
You may want to try narrowing down with some debug timing output if it
is slow to fetch the data, slow to render the components, or just slow
to send the data to the browser.
