[NTG-pdftex] processing speed

[Philip TAYLOR (Ret'd)]

An interesting note from DEL on a related prolem :


>   [ dek:
>         I think the strings are also needed for font file names.
>         For ordinary input files I put the special code into \S537
>         [which CET1 disabled] so that the Math Reviews could input
>         lots of files.
>         Of course there's a workaround (using the operating system
>         to concatenate files!) but otherwise all I can suggest is a
>         local change-file routine that tries to reclaim string space
>         when closing files if the unneeded strings are still at the
>         end of the string pool.  You could introduce a new array
>         indexed by 1..max_in_open to keep relevant status information
>         if it isn't already present (see \S304).
