Yes, I did profile it with Devel::DProf. Sdbm is not the biggest concern, but maybe the only one left optimizable as it is the last really accessing the disk...

Does sdbm really "re-hash (my) key into an internal key."?? The data I am hashing is about 300bytes and I did the hashing to reduce data while getting a (quite) unique key... My understanding was that sdbm would 1:1 use the supplied data as key, but if it really hashes it - I would revert to feeding it the original.. Are you sure?

What about the "feed the data sorted"? Is there any advantage in doing so?

And what about reducing pagesize? Ever tried?? (and can I anticipate what sdbm hashes it to? Sorting senseless??)
