      Description

      The read REST requests are slower after LTS 2016.
      It sounds that the minimum response time increase from 3ms to 10ms.

      Looking at the continuous benchmark for 2 MongoDB in Read simulation the response show increases:

      • 18w11 Today we are at 17.5ms (+/- 14) mostly around 16ms
      • 17w37 From 12.4ms (/11) to 15.6ms (/ 21).
      • 17w02 was at 7ms (+/-4)
      • 16w49 6.9ms (+/-8) LTS 2016

      Also, we can see in LTS 2016 that with 4 nodes we can have even had 2.7ms (/- 1) vs LTS 2017 at best 11ms (/- 14).

      A very low response time is needed to keep very high sync throughput.

      We need to understand exactly where these incompressible 10ms are spent.

      Possible cause:

      • tomcat maxThreads changed from 150 to 20 -> NXP-23318
      • audit entries is saved into chronicle log first
      • mongodb directory slower than sql
      • ...
