A pre-populated table lookup method can be very fast if your CPU has a large cache and you are doing lots of these operations in a tight loop. However it can suffer because of the expense of a 'cache miss', where the CPU has to fetch some of the table from main memory....
If you do it a lot, you are better off batching up bytes into words or doublewords, and doing fast bitcount operations on these. These tend to be pure arithmetic, since you can't realistically lookup a 32 bit value in an array to get its bitcount. Instead you combine values by shiftin...
