Does the recent Meltdown and Spectre OS patches affect the DSTM Miner's performance?
Has anybody done any before/after benchmarks?

From what, I read the recent Meltdown patch (KPTI) affects any programs that call the Kernel frequently such as netwoking, SSD disk access and CUDA memory copy operations from host to GPU.

How often does the DSTM Miner call the Kernel, anyway ?
