Maybe you can keep a counter in the routines of astrings. Increase/adjust on newansistring or setlength. > I'd like to know this, in particular, for FPC ana Lazarus --to begin with. > > And, the reason I'd like to know this is this: Whenever I suggest that > char size be increased to 4, the idea gets opposed on the grouds that it > will need huge memory --4 times as much. That's not the only reason: - more memory also means slower copy. - Most OSes seem to use uTF-8 and UTF-16, with -32 you would an island, and the avg text editors might not be able to read what you write > There's of course some merit in that arguement, but I have no idea what > it is '4 times' of. > This is not very engineer-like --it being unmeasured. It is highly dependant on use. An attempt on a single application says nothing. The app that I work on for a living has maybe 0.5MB of strings, and hardly any time consuming processing. (mostly a simple logfile). In previous jobs however I have done database-in-memory, database pumps and importers, and there it matters. > Can anyone suggest a way to measure the memory load caused by strings? _______________________________________________ fpc-devel maillist - [email protected] http://lists.freepascal.org/mailman/listinfo/fpc-devel
