      #ifdef MONGO_PLATFORM_64
          const int ReplSetImpl::replWriterThreadCount = 16;
          const int ReplSetImpl::replPrefetcherThreadCount = 16;
      #else
          const int ReplSetImpl::replWriterThreadCount = 2;
          const int ReplSetImpl::replPrefetcherThreadCount = 2;
      #endif
      

      These are reasonable default, but we can make them tunable (exporting them via serverParameter) so that people can tune according to their needs. This also facilitates perf testing.
