The replicat is running very slow on the ACFS filesystem.

It has been seen that when the replicat checkpoint file (<OGG_Home>/dirchk/<replicat>.cpr) is on ACFS , the performance of the replicat degrades. Also, it may not be necessary  the other replicats suffer with the same performance problem.

When checking the trace/trace2 file, we could see high amount in checkpointing (which includes updating the checkpoint file, reading trail files ).

Truss on the replicat may show high time being spent on the fsync.
