Blobfuse does not mount fast enough

[amnguye]

Which version of the blobfuse was used?

n/a

Which OS (please include version) are you using?

What problem was encountered?

blobfuse does not mount containers fast enough. In comparison to a Azure File Share, it took 1 hour and 40 minutes to be mounted twice, while in comparison to mounting a Azure File Share it took less than a minute

Have you found a mitigation/solution?

no

By default, blobfuse logs errors to syslog. If this is relevant, is there anything in the syslog that might be helpful?

:bulb: Thanks for this incident in the log, I was thinking of logging something similar recently (but had no dataset hence resisted).

• If possible can you please share the dataset which makes this issue visible? or probably steps to repro? Reason: I test with not so heavy work load so I don't notice it but few folks have mentioned recently (yet to confirm dataset) that they can see the performance hit. (I will keep you posted) personally with one mount with blob with just few files I don't see much of performance hit or delay hence asking for steps to repro.

I tried a 5 petabyte storage container but cannot repro this is version 1,3,4. Closing it therefore.
