This provides the endian conversion functions form endian.h on Windows, Linux, *BSD, Mac OS X, and QNX. You still need to use -std=gnu99 instead of -std=c99 for gcc. The functions might actually be macros. Functions: htobe16, htole16, be16toh, le16toh, htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh. License: I hereby put …

ZeroMQ Perl Performance Comparison: FFI vs XS bindings

ØMQ Perl Performance Comparison: FFI vs XS bindings

Comparison of the performance of FFI vs XS zeromq bindings. For FFI the ZMQ::FFI bindings are used, first using FFI::Raw on the backend and then using FFI::Platypus. For XS ZMQ::LibZMQ3 is used.

Comparison is done using the zeromq weather station example, first by timing wuclient.pl using the various implementations, and then by profiling wuserver.pl using Devel::NYTProf. When profiling the server is changed to simply publish 1 million messages and exit.
