* check isset for all elements first, as array_diff is much more expensive * Improves performance by 1%
* sort is much more expensive than count, so we only sort if we have something to sort * could implement for ksort too, but advantage there is minimal since we almost always have more than 1 possibility * use same hash algorithm as in other places (= faster) * reduces runtime by 2-3%
improves performance by ~1-1.5%
* do not concatenate with timestamp as this is slow, since $file_contents may be big * use file contents not file path for cache hash only to ensure it works if file_path not set but file_content is * improves performance by ~5%
* reduces I/O by 30% * minimal performance improvement (<0.5%)

Branch is ready to be merged. Sorry for many force push, but the tests don't work for me locally. Some step by step guidance/link on how to run the tests locally (or where the composer is installed, even when on a remote server) would be appreciated. |

Improve various minor things to speed up psalm performance by about 10%
No negative impact on memory consumption.
Will invalidate old caches (= most cache files created with any previous psalm versions will not be used anymore and new caches will be created on first run, since the cache hash changed for performance reasons)
