in reply to Faster than soap ?

I using SOAP 3 years ago, for 2 applications, but with standalone server.

For many time I deny questions about performance, but when working at a client side and many requests, the problems is more evident. But I think the great problem is the tcp negotiate.

Some times ago I see some work around keep-alive methods on SOAP::Lite code, but don't really understand the use.

Some benchmarks are need to identify the really problem, but I think the great problem at client site are a tcp connect...

After other some needs I'm used Connection Cache(LWP::ConnCache) on LWP::UserAgent, and waiting time for find/write other SOAP::Transport Client/Daemon my use (some external clients are java ;) )

Sorry, but I only have more questions ;)

For some practical samples, see my check code for single benchmark on standalone server:
Server - host 1:

  • Used with perl -d:DProf server.pl
    use SOAP::Transport::HTTP; my $daemon = SOAP::Transport::HTTP::Daemon -> new (LocalPort => 8080, Reuse => 1) # register serializer -> dispatch_to( qw(Server::Benchmark) ) ; print "Contact to SOAP server at ", $daemon->url, "\n"; $daemon->handle; package Server::Benchmark; sub ping { print "-"; return time; }
    Client - host 2:

  • Used with perl -d:DProf client.pl
    use SOAP::Lite; my $soap = SOAP::Lite -> uri('http://localhost/Server/Benchmark') -> proxy('http://host_1_server:8080'); foreach ( 1 .. 1000 ) { $soap->ping(1)->result; }
    * This code are quick made with SOAP::Lite Cookbook. I'm conclude: The client side use many time, lot with network call, on a good network!

    But, others Benchmarks with your real app are a good checks ;)

    My results on execute...
