Yes, use standard profiling tools. gprof will give you some idea, but oprofile is much more accurate. Rich. -- Richard Jones Red Hat ^ permalink raw reply [flat|nested] 5+ messages in thread

Is 'perf' from the linux kernel source tree, /usr/src/linux/tools/perf i believe, useful here? I tend to find it more useful and simpler than oprofile - but I am not sure you can find the gc-entry point. -- J. ^ permalink raw reply [flat|nested] 5+ messages in thread

However, systemtap is really interesting. [From a language perspective ...] it's a type-safe language with type inference that compiles down to C, compiles the C into a kernel module which is injected into the Linux kernel and lets you do all sorts of amazing stuff. The fact that it's a mainstream tool that uses proper type inference is significant alone, the fact that it's seriously useful is icing on the cake. http://sourceware.org/systemtap/examples/keyword-index.html Rich. -- Richard Jones Red Hat ^ permalink raw reply [flat|nested] 5+ messages in thread
