I tested a before an after of the clinical exam example. It was ~147kb to 148kb in 
both the new 
(pil2) and the former (windowspil) parsers.

While this may not be the reason for the increased filesize of your documents that you 
have, 
some possibilities are:

(1) Your documents have some full-size linked, pannable images. In the former parser, 
this 
feature was broken for the last few months, so the full sized versions wouldn't be 
included, 
and thus have smaller filesizes. If you don't want full-sized linked versions, there 
is a radio 
button for that in channel dialog > images tab > only include thumbnail.

(2) When the former parser would convert a color picture down to a black and white, 
the result 
would often be just a bit single black part of picture, looking like spilled ink. That 
black 
part, though not much to look at, would probably compress well, since it has long 
stretches of 
repeating color pixles in a row. The new parser converts images down to a nicer 
dither, for 
example black and white versions of photos are actually readable instead of a big 
black blob. 
However, since it is now no longer a ink blot, but alternating white and black pixels, 
that 
image would be larger when compressed.

Best wishes,
Robert
