00:00:37 hmm i need to fix a few things and re-profile 00:01:21 Just as a stab in the dark: does this involve processing matrices ? 00:03:29 Check /proc/sys/kernel/kptr_restrict before running 'perf record'. 00:03:29 00:03:47 i don't think i got all the symbols , i'm seeing stuff like 0x18ea93a instead of names 00:04:12 gbyers: nope, collision detection using quadtrees. 00:04:27 at least i strongly suspect that that is where the error is. 00:04:36 You loaded all of your code before saving the image with ELF symbols prepended ? 00:04:37 s/error/performance discrepancy between SBCL and CCL. 00:04:42 yes. 00:05:08 and ran the game from the command line with perf record ~/ccl/lx86cl -I image-for-profiling -e "(2x0ng:2x0ng 1)" -e "(quit)" 00:05:46 played the game for maybe fifteen seconds , once on level 1 (ok framerate) and once on level 7 (larger level where framerate drops to single digits) 00:05:59 and saved as two separate data files. 00:07:22 Dunno. Seeing lisp functions identified by hex addresses suggests that it's not finding those ELF symbols, but I don't know exactly what you're looking at. 00:07:37 i can put up the text on pastebin. hang on. 00:08:08 http://pastebin.com/raw.php?i=k5UCX3RY 00:08:16 Hmm. I didn't -say- that I had time/interest in looking at it, but ... OK. 00:08:22 i'm sorry. 00:08:40 i'm sure i'll figure it out. 00:11:16 -!- dto [~user@pool-96-252-62-13.bstnma.fios.verizon.net] has quit [Remote host closed the connection] 00:12:05 Maybe some runtime type lookup, things like (typep foo x), where X is non-constant ?
