Try playing a little bit with the database: tuning the BLOB segment
size, the database page size and the number of pages in the cache. You
should use GBAK or another utility to create tuned copies of your
database and begin the testing on them.


Possibly, you can read the blobs faster after the first time because
the pages are in the cache.


Cheers,

Raúl.
