Are there any references available that would detail the tricks /
traps relating to the storage and retrieval of large quantities of
blobs in Firebird?

We have a system that is implemented in both FB and SQL Server. FB
performance is good or optimizable in all areas except for binary blob
storage.

I read that blob data is stored in pages and if the blob is bigger
than the page it spans multiple pages, which causes the slowness etc.

We have found that when databases get large in FB performance really
suffers. In SQL Server you don't notice a difference.

Are there ways to optimize the performance of blob lookup and
retrieval in FB? Our blobs are binary TIFFs, so I don't think filters
would help.

Thanks for any pointers/suggestions.
