Disk Speed Bandwidth Capped // SLOW DISK

Featured Replies

When accessing certain files, I noticed a significant drop in response speed. After running a speed test, I discovered that bandwidth was being capped on the following drives:

storagetwo (sdc)

storagetwo2 (sdd)

storage3 (sdh)

This limitation is affecting performance. Any insights on how to resolve this?

That looks normal to me, why do you say they are capped?

  • Community Expert

You do not indicate what speed you are getting that you think means it is 'capped'

 

A couple of shares have files in a location that is wrong for the share settings:

F----------h                      shareUseCache="only"    # Share exists on storage, cache
N------------2                    shareUseCache="only"    # Share exists on storagetwo, storage

This will stop them being treated as 'Exclusive' shares (to bypass Fuse level in Unraid) which is what you tend to want to maximise SMB performance.

When I transfer files, open a RAR file, or access a folder, everything runs slowly. Additionally, when I ran a test, I received a speed cap warning.

I appreciate the insight! I'll check this out—thanks!

Where?

 

Do a local transfer with pv and post the results:

 

pv /path/to/large/file > /mnt/poolname/file
