Hi Gael,
1 controller, 2 backends (MySQL 5.1) and 1 recovery (MySQL 5.1)
You don't need group communication with a single controller. The
performance might be altered by the way the group communication handles
loopback delivery.
I can start the controller and enable the backends. I can also access
the cluster and perform some queries. Items appeared on the backends.
Everything seems to work fine.
However, I noticed bad performances, especially for insertion queries.
A simple insertion in a virtual database takes about 0.500 s.
Does anybody already notice that kind of measures? I'm looking for a
way to optimize these queries. I tried different appia configurations,
but I wasn't able to find one which correspond to what I expected.
From your config file it looks like the 2 backends are collocated on
the same machine with the controller. This probably defeats the purpose
of both performance scalability and availability, so I don't know how
relevant performance measurements on such configuration could be. We
usually use such config for testing only (mostly functional) but not for
performance.
Don't hesitate to keep us posted with your findings,
Emmanuel
