[photran] editor performance

["Russell C. Johns" <johns@xxxxxxxx>]

Hi -

 I have been testing the new beta2 version of photran 3.0.0 and it seems
that the editor is very sensitive to file size.  The editor is very
snappy and responsive on a new file that I am creating which is still
less than a hundred lines long, but on a module that I am modifying,
where the file length is about 5,500 lines it is painfully slow and
draws about 1 character every 2 seconds or so.  

I am using somewhat antique hardware for this test, It's a pentium -
III / 1 GHz with ~ 1 GB RAM on RHEL4 (Linux).  

Is this to be expected for the editor? This is somewhat new for me as
generally my experience is that editors are limited more by screen
refresh/redraw rather than off screen file size.  

Perhaps it has to do with the syntax parser running coupled to the
editor, where it is then trying to reparse the source after each
keystroke?  if so,  then perhaps an option to have it reparse the whole
file at some less frequent interval such as every word or line would be
very useful.  

Thank you for your attention
