Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Jan Seiffert has been looking into vectorising the adler32 routine in zlib.  
According to Michael Hope, on the ARM Cortex-A9, there's a 3.0 x improvement to 
be had on blocks that fit in the L1 cache and a 2.1 x improvement for larger 
blocks.
