[Lustre-discuss] 1.8.1.1 write slow performance :/

[Piotr Wadas]

To be exact, I got similar rates with hundred files , one megabyte each.
so it's rather not about size of the files. 
Lustre client rate is 100+ download and 4.9 upload, and 
nfs => remote nfs => local lustre client => local lustre server,
via the same ethernet interface, is 180+ download and ~100 upload.

With upload to remote server data are read from local /dev/zero and 
written to drbd volume, download from remote server data are read from 
file, and written to local ext3 volume, in both cases.

...

DT
