First bad commit:ed579e50c66db90485593c6c79f5366a57145f2a Author: Morten Br=C3=B8rup Date: Mon Jan 24 15:59:53 2022 +0100 mempool: test performance with constant n "What gets measured gets done." This patch adds mempool performance tests where the number of objects to put and get is constant at compile time, which may significantly improve the performance of these functions. [*] Also, it is ensured that the array holding the object used for testing is cache line aligned, for maximum performance. And finally, the following entries are added to the list of tests: - Number of kept objects: 512 - Number of objects to get and to put: The number of pointers fitting into a cache line, i.e. 8 or 16 [*] Some example performance test (with cache) results: get_bulk=3D4 put_bulk=3D4 keep=3D128 constant_n=3Dfalse rate_persec=3D28048= 0972 get_bulk=3D4 put_bulk=3D4 keep=3D128 constant_n=3Dtrue rate_persec=3D622159= 462 get_bulk=3D8 put_bulk=3D8 keep=3D128 constant_n=3Dfalse rate_persec=3D47796= 7155 get_bulk=3D8 put_bulk=3D8 keep=3D128 constant_n=3Dtrue rate_persec=3D917582= 643 get_bulk=3D32 put_bulk=3D32 keep=3D32 constant_n=3Dfalse rate_persec=3D8712= 48691 get_bulk=3D32 put_bulk=3D32 keep=3D32 constant_n=3Dtrue rate_persec=3D11340= 21836 Signed-off-by: Morten Br=C3=B8rup Signed-off-by: Olivier Matz --=20 You are receiving this mail because: You are the assignee for the bug.=
