The reason I ask is because I thought there were some concerns about leaks ( probably just stuff I saw skimming various google hits ) and I have seen firefox and iceweasel light up my disk on very simple things ( like typing stuff into forms). As I started looking through the code, one of the first things I saw was something that looked like a hash table of previously used pages- are there static "junk bins" of strong references and stuff like that that could create memory leaks as they accumulate stuff and never get cleaned or pruned?
The other thing is that IMO ( opposing views welcome) memory access patterns are often an unappreciated issue on many architectures. The reason I reacted to the threading question as I did is that it seems, again in my opinion on superficial/ anecdotal analysis, that this approach often seems attractive but contains a number of issues, among them those related to memory or other resource allocations, that reduce the effectiveness even with an ideal multi-CPU system I did make this point before with reference to one speed-versus-threads graph from IEEE, http://lists.boost.org/boost-users/2008/11/42263.php Ceratinly " your mileage may vary" but resource allocation and contention is probably already a big deal and it may be a better place to look for optimization. Launching a thread is a general idea that can be used anywhere but digging into code may be more effort and more specialized to a given task however. Thoughts?
