Hi,
I am also observing bad performance with small files on a GlusterFS 3.7.11
cluster. For example if I unpack the latest Linux kernel tar file it takes
roughly 9 minutes whereas on my laptop it takes 30 seconds.
Maybe there are a some paramters on the GlusterFS side which could help to fine
tune the hosting of a lof of (mostly small) files? Does anyone have any
recommendations here?
RegardsML

Hello there,
We've had serious CPU utilization issues with pre 3.7.9 GlusterFS, due to huge
number of small files. CPU load was going up to 40-50 (on 32 core system) with
nothing else running on it.We've observed multiple other Gluster users
reporting similar issues, and waited for bug fix to be released. It seems like
SHD freeze issue is resolved with 3.7.10 and now we're upgrading 3.7.11 however
now we're observing very slow heal speed between nodes.
I see people are mostly using Gluster for storage backend to OpenStack to house
large VM images. I've used Gluster back in 2010, before RH purchase, but my use
case had smaller number of files back then.Has anyone else have experience with
hosting large number of small files on GlusterFS cluster ?
Thank you
