Maybe PGF creates a lot of control sequences at runtime, using \csname and \endcsname in macros. This would increase the control sequence hash and then it takes more time to find a particular macro.
neglectable, and not increasing during the run i guess
seems so, hash fill level doesn't change. seems also that it has nothing to do with \input! Since when i replace \input by .so and use soelim -t to expand the input files to some huge file 4505098590 30. Mai 01:14 testplain-so.tex the slow-down is about the same. Also top shows no increase of pdftex memory usage. Weird. Regards, Hartmut
