Can you elaborate what parts it improves and do you have any benchmarks already? I went over the code very quickly and one small remark: In your php_pco.h header you're having C++ code, please make sure that this header is C compatible as it is included from main/builtin_functions.c in case somebody does a static build. For this reason it is suggested to keep only the minimal information there and add other declarations to custom headers. In config.m4 you are assuming some libraries are available and are setting some flags which seem to be compiler-specific. It would be good to add proper checks there. johannes
