SQL 2014 and Trace Flags

  • So I know this is going to be a loaded question, but just wanted to see what Trace Flags others are enabling on SQL 2014 servers.

    We have a few servers that hold about 100 OLTP databases each.  Performance is not bad, but think it could be better.

    I reviewed all the Trace Flags, but am looking to see what other have applied in the start up parameters.

    Currently we have the following trace flags enabled:
    T1117
    T1118
    T1204
    T3226
    T4199

    Thank you!!!

  • I honestly hate trace flag discussions.

    However, I'd suggest adding 2371 to the list.

  • Oh, and, you're on 2014. The system_health extended events session captures deadlocks. You don't need 1204. It's just going to dirty up your logs.
