How fast is SOAP::WSDL?
As of this writing, SOAP::WSDL is the fastest SOAP Client toolkit for perl available on CPAN. There are no published server benchmarks yet. If you need extra speed you can try SOAP::WSDL_XS available from SOAP::WSDL’s subversion repository at: https://soap-wsdl.svn.sourceforge.net/svnroot/soap-wsdl/SOAP-WSDL_XS/trunk Note however that SOAP::WSDL_XS is not very mature yet and only suitable for use in trusted environments – you definitely should not use it on a public internet SOAP server yet. Note further that SOAP::WSDL’s inside-out objects come with a big performance penalty when freezing/thawing them with Storable.
