We have a PS6500 running iSCSI and since i'm new to the equallogic world I would like to find out just what is too much Latency.  I seem to thing we have some issues and others say different.  When I look at SanHQ and run a Live View Session i get the following numbers..

During a volume replication I get anything from 30ms to 90ms Avg Read Latency

During a volume replication I get anything from 1ms to 24ms Avg Write Latency

During no replication I get anything from 6ms to 15ms Avg Read Latency

During no replication I get anything from .5ms to 13ms Avg Write Latency

I seem to think that at either time those numbers are pretty high.  Just curious what others might be getting and what good numbers should look like.  Any comments or suggestions are welcome.  Thanks!!
