SoapClient::__soapCall() profiling

[TomNomNom]

Woo! My first topic!

 

I've been writing a complex-ish SOAP client app with PHP 5.2.10.

It's turned out to be dog-slow, so I pumped it through the XDebug profiler and threw the output into WinCacheGrind.

 

SoapClient->__soapCall() is taking up 99.54% of the script execution time (~970ms). Being an internal function, the XDebug profile can give me no information on what it's doing.

 

What's the best way for me to find out what's taking __soapCall() so long?

I've done a request to the same SOAP server from a SOAP client on my workstation and it takes ~10ms.

 

I'm going to throw the uri of the SOAP server into /etc/hosts to try and see if it's the DNS lookup that's taking the time, but I thought someone here might offer a better method than trial and improvement :-)

 

Thank you!

 

**EDIT**

 

I forgot to mention. The script has to connect to the SOAP server over SSL and through a proxy. I used the same setup for the SOAP client on my workstation.

 

I tried putting the URIs of the SOAP server and the proxy in /etc/hosts and it sped it up a little, but not much.
