We have a weird issue while we setting up the AlwaysOn on Azure VM. We have explicit transactions in our stored procedures, and which are causing some delays and blocking when till the time we get the response from Secondary Server. We are in Synchronous commit mode of AlwaysOn to achieve High-Availability. But it seems we are seeing issues there as when we do the explicit commit the transactions are taking lot of time to complete and causing blockings. The transaction generaly gets stuck at "HADR_SYNC_COMMIT" wait type.
When we removed the explicit transactions from the stored procedures, the execution of the stored procedures was pretty faster and there were no blockings post that.
Anyone aware of any specifics about behaviour of AlwaysOn on Azure VM
Thank you.
