Hello Rooters!

I have questions about root file size... I save a Tree in a file  (with
1 branch)
and I want to make this file as small as possible...
Fisrtly, I was thinking that in the SetCompressionLevel(J) function, for
bigger J, the filesize should be smaller. But It don't seem to be... Is
it normal or am I doing something wrong?
Secondly, I have remarked that the file size is very dependent to the
Branch  buffersize; but I don't know how: If for a given number of
entries I find "the best" buffer size, for a different number of entries
the "best" buffer size is also different. Why ?
Thank you for your answer,

Olivier Meplan
