The bustek is supposed to be fully compatible with the Adaptec and should
therefore have very similar performance numbers (as your test showed).

If someone told you it has 3x better performance, they were comparing
some other card to it.  Maybe the bustek EISA to the Adaptec ISA or
the bustek to a ST-506.
