Amdahl's law very much applies, and doesn't explicitly only involve concurrency. It is about relating speedups of individual pieces and how that affects the whole. For example: Lets say that processing a representative query involves ten different places in the SQLite code, and that each one of those takes about ten percent of the total execution time. And then lets say likely/unlikely speeds up one of those by ten percent. The overall whole improvement will then be 1%. To get an overall improvement of 10% each of the ten different pieces would need to get about 10% faster. That would be a huge amount of work, and the nature of each of those places would have be that they could be sped up that way. > SQLite does not involve concurrency. http://sqlite.org/pragma.html#pragma_threads :-) Roger -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAla4u9gACgkQmOOfHg372QScKACeKaDcRUmtllIaCtLrvQOXYAoy tPsAoNH+TKDtsWsE9XeJHTVwKQ24MjJu =sPJZ -----END PGP SIGNATURE-----
