Subject: [xen/spinlock] e0fc17a9363: +24.6% aim9.dir_rtns_1.ops_per_sec
Hi Konrad,
We are glad to find that your patch increases the aim9 test
performance by up to +24.6%!
e0fc17a936334c08b2729fff87168c03fdecf5b6 ("xen/spinlock: Don't enable them unconditionally.")
test case: brickland3/aim9/5s-all
brickland3 is an Ivy Bridge-EX with 512G memory.
