Mirror job taking longer than an expected

  • I use redgate's SQL monitor to monitor my servers and lately my mirror job is taking longer then usual. It normally completes under a second running every minuted but i get spikes which are happening more frequently and can take up to 20 secs to mirror the data. The servers are literally next to each other so its not a network issue.

    I get alerts in this order normally

    Do you guys/gals know any counters or tests i can use to try find out why this latency is occurring?

    Thanks

    Although they are next to each other, they presumbaly plug into a network switch, is this the same switch or different switches?

    They are both connected to 2 different switches in case one of the switches fails. Both are connected to switch A and both are connected to Switch B.

  • are the NICs teamed then?

    Yes they are teamed, one can transfer only and the other can transfer and receive. Both seem to be running fine with no faults.
