Re: phpng: Refactored PHP Engine with Big Performance Improvement

In case you care about few additional req/sec it must not be a problem to do it on most major Linux distributions. $ CC="gcc -m32" ./configure --without-pic .... anyway, 64-bit phpng gets much more improvement because of reduced memory consumption. Thanks.
