Makes one wonder if excessive, delayed file system sync operations
were the issue, in writes.  This might be tested by performing pure
read operations in the file system ('cp SomeFile /dev/null' is a
basic test, versus copying file to file).

 
I realize I'm chiming in very late on this one, but that is a consistent 
problem with using Solaris boxes as TSM servers. Mounted filesystems give much, 
much slower performance than raw filesystems for the database, recovery log, 
and storage pools.
 
If it's Sun, it needs to be raw.
