Could you please check why this is happening.

  • I would add a few additional details to this: What version of MongoDB were you running prior to 2.6.4? Where are you measuring insert time (client, db log, ?). How long were you inserts taking before upgrade? – James Wahlin Sep 17 '14 at 13:04
  • I was running 2.4.2 version before 2.6 – viren Dec 9 '14 at 4:59
  • Can you upgrade to 2.6.5 and see whether it improves performance? The MongoDB query engine was rewritten for 2.6 and there have been regressions fixed with each minor release. It could be that your read/update path is not running as efficiently and impacting insert latency as a side-affect. – James Wahlin Dec 9 '14 at 14:28
