Importing for clearcase UCM stream is very slow

I have around 8000 files to import and it seems to take 5-8 hours to import the files to first time. Is that seems reasonable.

The ves of the dynamic view is on the syncronization machine but I know that dynamic views are very slow. I hope that after the first syncronization it will be faster to syncronize . Do you intend to support snapshot views as well ?

Any guidance on how to improve performance?

Improving the speed of importing is the top priority for the next
(1.0.1) release of the ClearCase Connector. What you are currently
seeing is the expected speed for 1.0 (actually, somewhat faster than the
expected speed, we predict 5-10 seconds per file, and you are getting
3-4 seconds per file).

Much of our cost is accessing the metadata from ClearCase, so we would
not expect a speedup from the use of snapshot views. In addition, with
snapshot views, one would need to pay the cost of an "update", which can
often be more expensive that accessing the files through a dynamic view.

Cheers,
Geoff
