bad performance after uploading 6 short files

I am creating a little library and some performance problems appeared. Even an update on a simple description is delaying a lot with only 6 registers. The MER and aggregate source are attached. Should I isolate more the binary content ?
imho it's isolated enough.
just make sure you only grab the binary-data when downloading..

Yeah J,
   when I put the select inside a block, it worked well.

Thanks so much
