Replication Transactions per Second Benchmark

  • Does anyone have info on how many transactions per second transactional replication can handle?

    Server has 128GB RAM, 12 core 2 Process (24 core total) each transaction is approximately 32k.

    Publisher and Subscriber are on different servers on same LAN, separate disks for logs, data, indexes and tempDB.

    I've found data on how many transactions per second SQL Server can handle but nothing on replication.

  • It's not really possible to predict such a thing. Even if you knew precisely how much SQL Server could handle, you still have switches and routers on the LAN to contend with. Things will change if other network traffic occurs unless you have a dedicated fiber channel running directly from one box to another.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
