Hi Team , There is a performance issue with write operations , data insert to the database very slow in a sudden and will get back to normal in some seconds . Strange Logs like this :
As you can see , the op only locks the db for 2 or 3 ms but it cost 300ms to finish , there is only _id index on those tables , about 4,000 write ops every minute on those tables. Could you advise how to trouble shooting the issue ? Thanks, Carl Dong |

Just as a reminder, the SERVER project is for bug reports and feature requests of the core MongoDB software. It might make more sense to tracking troubleshooting and investigative projects via one of our support channels. I'm going to go ahead and close this issue, but we can reopen or open another if we find a specific related issue here.
I hope that this provides you with a good starting point to begin your troubleshooting! Regards, |
