Just curious, what do you do? It's interesting that you optimize a lot of C/C++ programs... game development maybe?

- Xichekolas 18y agoMy guess is something cryptographic.

- tptacek 18y agoNetwork security software, reverse engineering, and (a bit earlier in my career) streaming video/multicast. I got a 7x performance improvement in a performance-critical component at Arbor Networks within a couple weeks of starting there just by profiling, finding malloc/free at the top of the profile, and switching to an arena allocator. I have other malloc stories, but that's the simplest. I've learned to fear malloc.
- palish 18y agoI'd like to hear the other malloc/free stories whenever you're inclined.
