The description is not clear. What do you mean by slave delays? is it that the slave does not accept any requests?

The replication has almost no perf impact on the slaves. It is an I/O bound and not CPU bound .

> When using Java replication in v1.4 and doing a sync from master to slave, the slave delays for about 5-10 seconds. When using rsync this does not occur.
> Is there a way to thread better or lower the priority to not impact queries when it is bringing over the index files from the master? Maybe a separate process?
