It rarely is a bottleneck in single-threaded application. If I tried to make both apps actually USE that allocated memory, one or both of them would likely be killed (and possibly other apps on the system, too)...

up vote 29 down vote favorite 13 How much of a bottleneck is memory allocation/deallocation in typical real-world programs? The default allocation strategy is OK for most cases but it can be changed to suit whatever is needed.

I cannot see a test for null in the code. (Excepth that any iteration would possibly test for null as an end condition, sure.) –Peter A.

This obviously makes me think that something that I'm doing while loading in the graph data is corrupting the heap, but the odd thing is that the malloc call that fails This makes them fast and scalable. –EmeryBerger Sep 23 '15 at 17:21 @EmeryBerger: The default Microsoft and GNU C libraries didn't perform well for me in multithreaded testing in Of course, one thing to be aware of is that some systems (Linux being one major example) are designed around overcommitting of memory, such that malloc() basically will never fail, even http://www.sbras.ru/cgi-bin/www/unix_help/unix-man?malloc+3 Still even allocation objects in Java is very cheap, doing so for a lot of users of a web application in parallel can still lead to performance problems, because more Garbage

You can take this figure as an upper bound, i personally feel that a typical application spends more like 10-15% of execution time allocating/deallocating memory. Some of the Java virtual machines have enough memory configuration options to choke a horse. NEdit isn't really suited for editing huge files. Apparently, NEdit ran out of virtual memory, possibly because it hit a process limit (such as a datasize limit of 640MB).

  1. Are decent implementations of malloc/free/garbage collection fast enough that it's only a bottleneck in a few corner cases, or would most performance-critical software benefit significantly from trying to keep the amount
  2. Exiting because a malloc fails at startup is the prefered way, because the one starting it can immediately see it and do something about it.
  3. On the other side, almost all modern programming languages hide these operations behind "allocators" which work with pre-allocated buffers.

gethostbyintuition() is still a dream of mine Tell us about it. The downside is compacting the memory after GC to remove the holes.

Therefore there are those indirect costs of an allocation in Java caused by the deallocation done by the GC.

This is easy to work around, just sleep a while and retry the malloc, especially if you tried allocating just a little bit memory.
