[Adium-devl] Top 10 malloc call stacks in Adium

[David Smith]

	Using the wonderful malloc_history -all_by_count tool I have a  
document with a list of every memory allocation call stack in Adium  
(as of when I ran the report), grouped, and sorted by frequency. I've  
put the top 10* here: http://dscoder.com/adiumtop10mallocs.txt

Some things immediately stand out:

1) 3 functions are responsible for our top 10 malloc callstacks:  
purple_buddy_new, [AIPreferenceContainer prefs], and  
CFHTTPCookieStorageCopyCookiesForURL

2) (this is more informational, you can't tell it from the document)  
All 18000+ of the #1 call stack happen even with no internet  
connection, and therefore no active connections. In fact, once it's  
done those 18000 all at once on startup, that call stack never appears  
again.

	As for whether this data is actually worth something... hard to say.  
It looks to me like we should be able to allocate less in many of  
these situations, but I don't actually have any concrete improvements  
to suggest right now. It's also unclear how valuable allocating less  
would actually be; frequent calls to malloc is certainly a nice  
heuristic, but may not be all that related to what's actually causing  
high memory usage. So, caveat emptor, but I think there's probably  
something of use here :)


*the full output is 10MB. If people want it, I'll post it, but I  
figure the top 10 is probably more useful for now.
