    • Minor Change

      We are experiencing major bottleneck around following two calls on load, percentage time consumed by these two calls are given below.

      com.mongodb.util.SimplePool._get() (42%)
      com.mongodb.util.SimplePool.done() (37%)

      Please let us know if this is a known issue and there exist a fix for the same?
      Do we have any alternative to the SimplePool, which handles get and put connection more efficiently?
