This patch set makes memory allocations for data structures used in the I/O path more numa friendly by allocating them from the same numa node as the storage device. I've only converted a handful of drivers at this point. My testing showed that, for workloads where the I/O processes were not tied to the numa node housing the device, a speedup of around 6% was observed. When the I/O processes were tied to the numa node of the device, there was no measurable difference in my test setup. Given my relatively low-end setup[1], I wouldn't be surprised if others could show a more significant performance advantage. Comments would be greatly appreciated.
Sorry but I'm not familiar with any of the SCSI LLDs modified via this patch series. But I'm fine with the SCSI core patches in this series. So if you want you can add the following to the first five patches in this series:
