[RFC PATCH v2] Implement Batched (group) ticket lock
...B C D
ebizzy_0.5x -0.20 1.071 -0.07 1.39
ebizzy_1.0x 0.83 8.89 7.89 6.08
ebizzy_1.5x 24.11 38.39 5.42 42.56
ebizzy_2.0x 47.77 78.49 11.94 108.14
Observations:
With increased batch_size batch ticketlock has closer performanace
to unfair locks and very promising for kvm guests that expects
high performance of unfair locks with bounded starvation property of
fair locks.
Baremetal:
No significant performnce difference even for CONFIG_PARAVIRT_SPINLOCK enabled
on baremetal
