What is the optimal workload value for Kaspa GPU mining?

The optimal workload value for Kaspa GPU mining lies in the range of 256 to 1024. The default value of 16 is functional but conservative — raising it increases your hashrate, and miners do push values as high as 4096. However, larger workload chunks mean less granular work submissions, which increases submission latency. In Kaspa's blockDAG, even a modest latency of around 0.5 seconds does not typically affect whether a block is considered 'blue' (valid), but it does reduce the chance of your block landing on the main chain, which in turn reduces your chances of earning rewards from merged red blocks. The system is designed to reward responsiveness, so staying in the 256–1024 range lets you capture most of the hashrate benefit without sacrificing the low latency that keeps your blocks competitive.
