 Description   

we have some 3.4 sharding cluster, sometimes a node will become   extremely slow. it is very slower even if we are just conneting to the mongod process.

Maybe our data is a little big , the avgObjSize of many collections are hundreds of KB , if is it the main cause of a poor performance?

I have collect   perf top data and pstack , hope that can help you analyze the problem.

Hi lpc, since MongoDB 3.4 has reached EOL in January 2000, I will go ahead and close this ticket. MongoDB latest releases can be found here.

Regards,
Dima
