Minimum file length.

Minimum file length.

[John Culleton]

I am writing an e-book where pdf file length is an issue. For the 
minimal "Hello world" file I get the following lengths:
tex+dvips+ps2pdf 2820
pdftex                   5630
texexec               22,173

The only thing I added to the last test was the \starttext and 
\stoptext tags. The dvips etc. test defaulted to pdf 1.2,
the other two to pdf 1.4. I don't doubt that with more text the counts 
would be more similar. Still the fourfold increase between the second 
test and the third is a stunner. The e-book must be limited to 2 megs 
per the publisher. 

Just fyi

You could use XeTeX or LuaTeX instead of pdfTeX.

My example

\starttext
Hello World!
\stoptext

with the file size for each engine:

pdfTeX: 21.355
XeTeX:   3.155
LuaTeX:  3.328

lm type 1 in pftex is less efficient than opentype in xetex/luatex

there may also be some different initial overhead per engine
