There's a simple speed up by just commenting out code in keyspace.cpp for ((m_charaterEncoding & (CE_UTF16_LE | CE_UTF16_BE)) != 0) and ((m_charaterEncoding & (CE_UTF32_LE | CE_UTF32_BE)) != 0) but then NTLM will break. Next update will have a few changes for speeding up the reduction function such as three classes keyspace8, keyspace16, and keyspace32. Also needs variable length character support for UTF-8 and UTF-16. The key space used for benchmarking is loweralpha#1-7. This code can use key spaces such as Omni-6.
