 ## Known Limitations and Issues
 
 - If your master/slave/replicaset deployment is not updating correctly, check the log files at `/var/log/mongodb/mongodb.log` to see if there is an obvious reason ( port not open etc.).

- syncDelay:
- description: |
- Seconds between disk flushes. mongoperf.syncDelay is similar to --syncdelay for mongod.
-
- The syncDelay controls how frequently mongoperf performs an asynchronous disk flush of the memory mapped file used for testing. By default, mongod performs this operation every 60 seconds. Use syncDelay to test basic system performance of this type of operation.
-
- Only use syncDelay in conjunction with mmf set to true.
