It seems that the blocksize was already quite optimal, the best configuration from the kernel tuner is only 2% faster.

For further improvements, I think we should study 2stream and source_adding together. The former creates a lot of large fields that all are being reused in the latter. Probably a merged kernel could reduce the memory usage.
