I had already thought that halfway. Now with your updated version which also generates addresses it's much slower, the result is clearly different than just calculating the pubkey as you showed in your initial version. I get about 70,000 addresses/sec with your updated version: I realized that you output tuples of addresses using list(map). I suggest to adjust your program so it outputs a single address on each line so we compares apples by apples. I am not sure if the list output affects performance in some way, that's why I am pointing to it. The example I originally showed using iceland2k14/libsecp256k1 was about half the speed. With it I can generate 1 million addresses using all cores (in my case 16 cores) and write to the file in 4.8 seconds, this is a rate of about 208,300 keys/sec. I have modified my initial program so that you can now also configure the cores under which the program is executed. So one can select specifically "1" as value, so that we also compare apples with apples. Running this under one single core, now I get 26.5 sec for 1 million generated addresses. This is a rate of 37,735 keys/second. I am curious to see your program using all available cores.
