2019-03-05stdlib: Correct and optimize pretty printing of stringsHans Bolinder
Avoid traversing all of the list/string when only part of it will be used. An explicit check that the list is flat is needed since string:slice() accepts deep lists and more.

2019-02-14stdlib: Optimize formatted printing of termsHans Bolinder
Try calling iolist_size() before calling string:length(). The reason is that calls to string:length/1 are slow when the argument is not a list of integers (or contains UNICODE).

2019-01-31Optimize calendar:gregorian_days_to_date/1Stanislav Mayorov
This patch improves the performance of calendar:gregorian_days_to_date/1 by changing the algorithm for finding the year to log-logarithmic. The old implementation has linear complexity, which makes function too slow for large values. For example: There is an API that allows you to create events for future dates. There are users of this API who, for some reasons, choose dates very far in the future. In such conditions, function works very slow. New implementation based on interpolation search, takes 1 or 2 iterations at most cases and free from such a flaw. A unit test was also developed to illustrate the speed of a function at large values.

2019-01-21correct: Work around a compiler mis-optimizationRaimo Niskanen
This was not a compiler optimization that misfired, rather that the code neede separate case clauses for when the timer was running and not, so to not call erlang:cancel_timer/1 nor maps:remove/2 in the case clause where only a map update was needed before recursion. See the comment in loop_timouts_cancel/13

2019-01-17Work around a compiler mis-optimizationRaimo Niskanen
The common subexpression optimization accidentally caused unnecessary spilling of live registers. A rather ugly workaround can be found in loop_timeouts_cancel.
2019-01-17Move out helper functions to engine loopRaimo Niskanen
This strategy improves speed benchmarks and reduces the amount of garbage that is produced. More: * Handle transition options as loop function arguments instead of in a record. * Shorten the state_enter loop and make it more efficient by making it more part of the loop and less a loop restart. * Simplify the internal timeout action handling somewhat.

2019-01-14Optimize gen_statem engine loopRaimo Niskanen
* Use synchronolus cancel_timer since that is more efficient than asynchronous when a process cancels its own timer * Restructure the state to have fewer fields by breaking out practically constant fields into a separate loop argument record #params{}, group state and data into one field and dito for timer fields * Optimize engine loop arguments for staying in the loop so the detour to sys:handle_system_message/6 will require packing/unpacking of the sys: state, and of the argument Parent * Avoid double reverse of event queue in many cases * Restructure the state transition to not have duplicate tracks for sys_debug and non-sys_debug cases * Shortcut the empty list case where possible * Loop unroll reversal of up to 2-element lists to avoid calling lists:reverse/2 since an external call spills all live registers to the stack * Bring out the callback mode check to the engine loop
