Description Gordon Sim 2008-11-28 15:55:35 EST
A 40-50% regression in performance of the broker was introduced by r719699[1]. It is an issue with the management and can be avoided by turning management off (-m false).

(My guess - speculative - is that its due to more frequent use of the qpid::sys::now() function).

This regression has been fixed in the upstream revision r722120.
Comment 3 Frantisek Reznicek 2008-12-05 06:02:16 EST
Performance issue has been fixed. Running qpidd with and without management enabled provide now close comparable perftest results:

RHEL 5.2 (dhcp-lab-200)
starting qpidd with management on
starting qpidd with management off
.with management
78004.3 72638.1 146076 142.652
.without management
78203 76793.5 153621 150.02

RHEL 4.7 (nec-em15)
starting qpidd with management on
starting qpidd with management off
.with management
25815.3 25703.2 51603.2 50.3938
.without management
27150.8 27026.8 54270 52.9981

Validated on RHEL 5.2 / 4.7, i386 / x86_64 on packages: qpidd-0.3.722891-2.el5, rhm-0.3.2913-1.el5
