Compiled hash rate is currently about 1.5 million hashes/sec, which is Compiled hash rate is currently about 1.5 million hashes/sec, which is
about 2-3x slower than HashX compiled mode. about 2-3x slower than HashX compiled mode. Compilation is definitely
worth it for the solver, which runs 64K hashes per program.
Unfortunately, the compilation overhead makes this uncompetitive
with the C implementation.
Equi-X requires 1.8 MB of heap to find solutions. Equi-X requires 1.8 MB of heap to find solutions.
This implementation uses about the same, plus lots of Java overhead of course. This implementation uses about the same, plus lots of Java overhead of course.

PoW is currently single-threaded, multi-threading (one for each seed) is not yet supported.
PoW multi-threading would require 1.8 MB of heap for each thread.
PoW verification is relatively fast, as in the C code.
As verification only requires 8 hashes (vs 64K hashes for each solution attempt),
verification does not benefit from compilation as the overhead is too great.
