Hello:

Anyone have any preferences in regards to BLOB compression vs. performance.  I'll mainly
be using small (32K ish) and medium (2 to 5 meg) size images (in separate fields).

Thanks,

Dale

Dale,

What type of images?  If the images are already compressed, that could
possibly create extra performace hit in compressing something that can't be
compressed further?

They would png, jpg, bmp, and probably tiff.  I don't have any control over where our
users will get the images so I have to be ready to accept just about anything (within the
aforementioned formats).

Tiff and GIF would have the LZH.

You are right in that in general, you may not have control over the images.
That does become, though, an issue, much like zipping a bunch of images in
that it sometimes takes longer because its not finding much of any
compression to do, taking longer.

In a C/S situation, is the BLOB compression done on the server, or the client?

Dale,

On the server, although the BLOB data may be compressed/uncompressed on the
way to the server also if the TEDBSession.RemoteCompression level is higher
than 0.
