Title: Optimize hashing

Amount of memory allocations almost halved, now it's mostly Map updates.

Before:
total time = 8.71 secs (8711 ticks @ 1000 us, 1 processor)
total alloc = 12,220,615,792 bytes (excludes profiling overheads)

After:
total time = 5.02 secs (5022 ticks @ 1000 us, 1 processor)
total alloc = 7,753,908,480 bytes (excludes profiling overheads)
