Hi Sasha,
The error I got are "osm_db_store: ERR 6109: Failed to remove
file:/tmp//guid2lid" and "osm_db_store: ERR 6108: Failed to rename the db
file to:/tmp//guid2lid". I set "OSM_DEFAULT_CACHE_DIR" to "/tmp/". Could
it be the reason of slow?
Thanks!
Yicheng

In first run OpenSM will not fetch existing LFTs from the switch and
will setup this from "scratch". I think that the reason for delay should
be different. Also it is single-switch subnet, its setup should be
reasonably fast in both cases. Do you see any errors in OpenSM log file?

No. Port 0 is switch's management port and normally it doesn't have
physical connection.
