What are you using for compression?
Have you checked that you get a useful degree of compression on that
numeric data? You might find that it is not particularly amenable to
compression.

I have a blob structure which is primarily doubles. Is there anyone with

Tests I have
run so far indicate that compression is too slow on blobs of a few meg to
be practical.
I get now at least 20 to 40 inserts per second but if a single compression
takes over a
second, it's clearly not worth the trouble. Does anybody have experience
with a compression scheme with blobs that consist of mostly arrays of
doubles?
Some schemes ( ibsen) offer lightening speed decompression so if the
database was primarily used to read, this would be good choice but very
expensive to do
the compression required to make it.
