Hello,

We installed ADSM VM-server V1R1 Level 0.14 last week, to solve an
critical problem on migration processes, and tested the
"performance improvements" of EXPORT commands...

We submitted an EXPORT NODE nodename FILEDATA=BACKUPA DEVC=36TRKS
on a relatively small node.

Nice thing compared to Level 0.12 is that export does not loop !!

It took 4 hours to export 11k files for 580 MBytes !! ;
The strange thing is that the first input volume is requested 1 hour after
the start of the export process !!!

I'm a not very impressed by the performance improvements the way they are
implemented in Level 0.14

cheers, michel
