How to track down a latency/timing problem
...almost independently from the file?s
sizes. Dirs that have recently been accessed, are of course much faster
due to caching. There is no general performance problem as we are
getting almost 1G/s when reading/writing big files from two clients in
several threads. But when creating lots of files with lmdd in a test
script in a single thread there are also hangs of a few seconds before
the rates get back to normal.
I?ve been searching the mailing list archives for similar problems but
only found the usual "improving performance for small files" hints. All
these suggestions have been tested...

bad 1.6.3 striped write performance
Hi,
I''m seeing what can only be described as dismal striped write
performance from lustre 1.6.3 clients :-/
1.6.2 and 1.6.1 clients are fine. 1.6.4rc3 clients (from cvs a couple
of days ago) are also terrible.
the below shows that the OS (centos4.5/5) or fabric (gigE/IB) or lustre
version on the servers doesn''t matter - the problem is with the 1.6.3
and 1.6.4rc3 client kernels
