Hi
We've just checked-in 2 commits that reduce per-thread memory usage
as well as the default number of threads. The first commit should result
in lower memory usage in your vol file with 64 threads. Please let us
know the memory usage for the latest git with the same server side config.
You can see a brief description of the two commits here:

Thanks

hello again, after more test, glusterfd process memory grows with
ption thread-count 64 , perhaps is it normal ?
( count = 4 => 300 Mo , 16 => 600 Mo , 64 => 2.5Go )

I am looking into this. In the meantime, It'd help very much if
you can post the vol file.
Thanks Shehjar

hello, I just try last git tree, and it seems that's server
process ( glusterfsd ) takes a lot of memory ( >2 Go) whereas
with same config file and other version, glusterfsd process
take 300Mo
J've juste change , option thread-count 4 to option
thread-count 64 ( it seems that now thread count must be
between 32-512 ?)
