In my tests on Linux, mimalloc seems to run consistently faster than jemalloc and uses only slightly more memory in `analysis-stats` on chalk. Also, builds with mimalloc produce a binary 3MB smaller than builds with jemalloc.

For instance, for a vector of N elements: ``` [Message{level: (N - 1)}, ..., Message{level: 1}, Message{level: 0}] ``` we would first do a linear scan to find entry with level 0, then another scan to find one with level 1, etc. * It makes it much easier to improve the output in the future, because we now pre-compute the children for each entry and can easily take that into account when printing.

* Fix a corner case when printing unaccounted timeMichal Terepeta2020-01-191-4/+52
| | | | | | | | | | | | | | | | | | | | | | Previously `ra_prof` wouldn't actually print the unaccounted time in some cases. We would print, for instance, this: ``` 5ms - foo 2ms - bar ``` instead of: ``` 5ms - foo 2ms - bar 3ms - ??? ``` The fix is to properly handle the case when an entry has 0 children instead of using the `last` variable.

* Improve profiling output when duration filter is specifiedMichal Terepeta2020-01-021-4/+25
| | | | | | | | | | | | | | | In particular: - Use strict inequality for comparisons, since that's what the filter syntax supports. - Convert to millis for comparisons, since that's the unit used both for the filter and when printing. Now something like `RA_PROFILE='*>0'` will only print things that took at least 1ms (when rounded to millis). Signed-off-by: Michal Terepeta <[email protected]>
