    Decrease in WRITELOG waits leads to an increase in Memory/CPU waits

    jsql

      Hello,

       

      We have been testing a NetApp SSD to compare performance from our Hitachi SAN.  One of our "problem" databases is SolarWinds_NPM which has an enormous amount of WRITELOG waits.

      After migrating the server to SSD, the WRITELOGs went down significantly but the Memory/CPU waits went UP, almost by the same amount, almost eliminating the performance gain of the SSD.

      Why would this occur?  See attached.  Migration to NetApp was on June 6

       

      Thanks for any advice
