Exchange 2010 RPC Average Latency spikes RRS feed

  • Question

  • We have a two node DAG with single mailbox database mounted on each server and a copy on other servers, both the servers are installed with MB, CAS & HUB roles.

    One server with 900 mailbox with the database size of 650 GB showing RPC average latency spikes, where perfmon counter will show more than 60 to 120 ms at times. spikes will last for 2 to 4 minutes and it will come to normal as 18 to 20 ms. this is happening 5 to 7 times a day.

    Can someone help me in knowing why it is occurring and if the spike is because of some particular mailboxes, how to identify it and what action to take on those mailbox?
