Does anyone really know ? has anyone made say a page that collects a
few items from a form
and puts it in the cms ?. If someone has these tests why have they
not shared them ? If mmbase
is 10x slower using tags than something else with the same ease of
use we need to take hard look
at it. Thats why michiel and i want to add jmeter scripts to the
releases.
Hi, I think I still have some jmeter scripts used to do research on
the teleac clouds.
so perhaps I a allowed to share them.
I don't think the performance has to be measured to say a few things.
-We don't allow group updates
-The way we perform queries (the rope of nodemanagers) doesn't work well
on all structures so when importing data you have to perform a lot of
queries to know what data to import
-user->images
->companies
and if you start using nodeFields you are really screwed since you can
not create a subquery for getting the related node. this results in
many many queries,making imports really slow.
-import scripts need to do all kind of weird stuff in order to complete
for example using HugeNodeList or programming constraints in the
import functionality
since we don't have some kind of lazy loading
-a single node commit requires multiple sql insert/update statements.
-we don't optimize the database very well , so that's left to the
guru's who know a database and also know the mmbase object model.
But measuring is the first step , and some points can be fixed but at
least you know why I think
you can expect the performance to be less.
