My personal experience is that HTT did help. This was with an older

In my experience HTT helps 20-30% in a well engineered workload. Extreme
care needs to be taken on minimizing synchronization primitive overhead
or that will take away your gain. (don't have 4 or 8 threads hammering
on one mutex a million times a second)
