We tried to comment those lines and it doesnât seem to get rid of theI am running 1 and 2 Oracle DB instances each running TPC-C workload. The
performance regression we are seeing.
Can you elaborate a bit more about the test you are performing, what kind of
resources it uses ?
Can you also try to replicate our test and see if you see the same problem ?With this sysbench test I am not seeing any improvement with removing the

The reason we create a cpuset is to narrow down the investigation to just 4
cores on a highly powerful machine. It might not be needed if testing on a
