That's because statically linking is an outdated idea. There are no
performance nor security benefits. The only reason a traditional static
library is faster than a shared library is because a shared library is
usually build using PIC (Position Independent Code) which adds an offset
lookup table allowing the library to be linked into many different
binaries at the same time. Since libphp5.so is not a general-purpose
shared library, but tied implicitly to a specific SAPI, we build it
non-pic by default which means there is no performance difference.
