Hi,
I'm switching from sequential to keyed archiving for saving my
application's documents (I know, I'm a bit late...). Everything works
fine, except... With sequential archiving, saving the whole object
graph took 0.5 s, and with keyed archiving it takes 23 s!
In fact, it's not a matter of keyed or sequential archiving, since it
also takes about 23 s if I use NSKeyedArchiver for sequential archiving
(which it can do).
Is this a known issue? Is there a way to speed things up?
There have been previous comments about the performance of
NSKeyedArchiver as compared with other techniques. As far as I recall,
the problem with it is that it has to do a lot of work to ensure that
it doesn't fall foul of loops in your object graph... anyway, search
the archives for more information on this one.
Kind regards,
Alastair.
