Task | Runtime ms | Switches | Average delay ms | Maximum delay ms | Maximum delay at |
---------------------------------------------------------------------------------------------------------------
... | | | | |
git:24540 | 336.622 ms | 10 | avg: 0.032 ms | max: 0.062 ms | max at: 115610.111046 s
git:24541 | 0.457 ms | 1 | avg: 0.000 ms | max: 0.000 ms | max at: 0.000000 s
-----------------------------------------------------------------------------------------
TOTAL: | 396.542 ms | 353 |
---------------------------------------------------

After:
