Sorry if this has come up before, I've been off the list for a while...
I just installed Panther, and one feature in my app is now running very
much slower than under 10.2
I do a search and some processing on every item in a file with ~58,000
items (the file is about 600 kbytes), writing the output to a temporary
file and then displaying the accumulated results in a text field. This
used to execute in well under a second, now takes nearly 5 seconds on
my G4 1GHz 512mb Powerbook, which is probably intolerable for my users
with slower machines.
I thought at first it was excessive paging to allow the system to be
more more responsive, but looking at the Activity Monitor that doesn't
seem to be the reason;
my next guess the culprit is NSText readRFTDFromFile when I read the
file into the text field (the writing to file is done using fwrite).
Has anyone else experienced this method being much slower on large
files?
$@%? $@%? $@%? $@%? $@%? $@%? $@%? $@%? $@%?
