Subject Re: low persistent messaging performance using kahadb
Date Mon, 14 Dec 2009 10:04:52 GMT
Hi Duro,

kahadb has some trade-offs for scalability and recovery speed vs.
performance, but shouldn't that much slower. You can check
activemq-throughout.xml config and see if applying some the parameters
seen there can help you.

If performance is your main issue (not scalability and recovery) then
maybe amq store is the best choice for you.

Cheers
