MongoDB running in MacOs High Sierra write operation is very slow

[Rogério Alexandre Machado Carrasqueira]

Hi Guys!

I was running MongoDB 3.0 on my macbook with Sierra for proposal development, but after updating it to High Sierra, the write operations becomes so slow. I've tried to google about this matter but any results. I've changed my storage to WiredTiger nothing happens. Have anyone updated and got the same problem that I'm having here?

I'm putting my actual mongo.conf:

systemLog:

  destination: file

  path: /usr/local/var/log/mongodb/mongo.log

  logAppend: true

storage:

  dbPath: /usr/local/var/mongodb

  engine: "wiredTiger"

net:

  bindIp: 127.0.0.1

Thanks

Hi Rogério

“Slow” can be caused by many different things. Also, different use cases have different ideas of what “slow” means. Could you elaborate on what you’re seeing, e.g. before and after the OS upgrade, and what operation you’re trying to do? Is the issue consistent, or is it intermittent? It is also possible that the memory used by MongoDB is being swapped out of RAM into disk if you’re running many memory-intensive applications in your laptop.

Also, could you try upgrading to the latest MongoDB version (currently 3.4.10) and see if the issue persists?

Best regards
Kevin

Im not sure if this will help, but things became real slow after upgrading and following these instructions worked for me: https://dzone.com/articles/fixing-the-slow-startup-time-of-my-java-applicatio
