Tree compression Qs

Hi root talkers,

What does the error message:
"mmzip: output buffer too small for in-memory compression"
mean?

I get it when filling a tree with several separate branches.
Increasing the buffer size (from default 32000) to 128000 did not help.

What do I have to do to get rid of this message and to compress properly?

Also, I noticed when the buffsize is bigger than the whole event series
(so that only one buffer(Basket)  per branch is used) the branch is
NOT compressed at all. Is that intentional?

I also wondered what the compression levels 3-9 mean??
I found nothing in the docu and can't see any noticeable effect.
So why are they implemented and when/how to use them?

cheers
Peter
