We have the same issue (using dCache on Thumpers, data on ZFS).
A workaround has been to move the directory on a local UFS filesystem using a
low nbpi parameter.
However, this is not a solution.
Doesn't look like a threading problem, thanks anyway Jens !

I think I am having the same problem using a different application (Windchill).
zfs is consuming hugh amounts of memory and system (T2000) is performing
poorly. Occasionally it will take a long time (several hours) to do a snapshot.
Normally a snapshot will take a second or two. The application
Hi All,
Thank you for answers.
I am not really comparing anything.
I have a flat directory with a lot of small files inside. And I have a java
application that reads all these files when it starts. If this directory is
located on ZFS the application starts fast (15 mins) when the number of fi

Hi All,
We have a problem running a scientific application dCache on ZFS.
dCache is a java based software that allows to store huge datasets in pools.
One dCache pool consists of two directories pool/data and pool/control. The
real data goes into pool/data/
For each file in pool/data/ the pool
