MCM is Monero (XMR) CPU miner with the best performance. Originally based on xmrig (net and config) with completely rewritten algo from scratch on ASM.
On SSE4 (non AES-NI) cpu performance boost is up to 50% (depends on cpu architecture). More description on Github: https://github.com/alex-tk/mcm

Releases: https://github.com/alex-tk/mcm/releases

v0.9.6
 - added support for new algorithm cryptonight/r, short alias cn/r (also known as CryptoNightR or CryptoNight variant 4), for upcoming Monero fork

v0.9.5
 - added new algorithm cn-pico/trtl (aliases cryptonight-turtle, cn-trtl) for TurtleCoin (TRTL) fork.
 - added new algorithm cn/half for Masari and Stellite forks.

v0.9.4
+20% for cn/2 (CryptoNight variant 2 for Monero fork) --av=3 (Software AES implementation).

v0.9.3
- performance boost for CryptoNight variant 2 for Monero fork --av=3 (Software AES implementation)

v0.9.2
- added new algorithm CryptoNight variant 2 for Monero fork
- added CryptoNight-Lite and CryptoNight-Heavy support
- added SSL/TLS support for secure connections to pools
- based on xmrig 2.8.1 (https://github.com/xmrig/xmrig/blob/master/README.md)

v0.9.1
+2% performance boost for --av=0 (Software AES implementation)

Core2 Quad Q9300 2.5 GHz 6M, 1 & 4 threads, 64-bits, Software AES implementation
