Tuning in Mirror service

edit

Hi all,

After I added mirror serivce into my application, the throughput is dropped around 40% compared without mirror, I wonder there should be some tuning on the mirror service. My topology is 9 partition with 1 backup each.

As I have discovered these tunings in the forum (I guess there should be more), <bulk-size>100</bulk-size> <interval-millis>2000</interval-millis> <interval-opers>100</interval-opers> In fact, I hope someone could explain what these tunings are. (and right now, i include these tunings in the Application PU's pu.properties file)

I would like to ask any optimal tunings on the mirror service? The database I am using is MySQL 5.1, does anyone can advice on the DB side too?
