I didn't change API for ext/mysql* only for really often used functions. Before optimizing something, you'll need to check if you really have a bottleneck. Run some application with callgrind, then check how many times ZPP called from zip_pg_fetch() and its relative cost. If it less than 0.05%, it makes no sense to do anything. Over-optimization may make more harm than benefits. Thanks. Dmitry. > Regards, > > -- > Yasuo Ohgaki > yohg...@ohgaki.net >
