Off hand I don't really know what might cause the extra time.
It would be interesting to see the same profiling done at the C level
(i.e. see stats for the actual ct_fetch() call in Client Library) in
both versions of OpenClient.
Another possibility is that Sybase::Simple 0.51 uses the "return a
reference" option of ct_fetch, while 0.54 doesn't (no, I haven't checked
if that's the case, but you can check the ct_fetch() call in ArrayOfHash
to see if it passes a "true" value as the second parameter)
