> 60% speedup on int32 and 100% on int64 is great! However, it does seem to me like there is something else taking time from your results. I would expect speedup closer to the number of cores in your system. So there is some more constant time, the building of the frameblock a few lines before the `.convert` calls for example is around 400ms. I looked at the profiling a bit more and it seems like most time is spent on socket communication between Java and Python. My assumption would be that this adds quite a bit of overhead and doesn't parallelize well. -- This is an automated message from the Apache Git Service.
