Broker (qpidd) footprint

[William Henry <wh...@redhat.com>]

Has anyone done any broker memory footprint sizing exercises?

I've done a very adhoc and limited investigation. I see that a default qpidd without any plugins seems to use 5Mb of memory (5072Kb). As I added some queues and exchanges I saw 8Kb increases. Sometimes it didn't seem linear. E.g. is appears that adding exchanges will only see the 8K increase every 2 exchanges.

(Test done on 64bit Fedora 11 on a Lenova Thinkpad T61)
 
Is this is line with other peoples findings?

I haven't done anything with plugins yet but I'd be interested in some feedback or if anyone has developed a script for testing footprint scalability.

Best,
William

yea, that is because of the way Linux grabs memory pages, and it does 
not run mem consolidate until it needs to
