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 ;)
