Bug #75085 [NEW]: SoapClient - Bad performance - Too many reassembled tcp packets
From: dgimenez at novac dot es
Operating system: Fedora 26 Server x64
PHP version: 7.1.8
Package: SOAP related
Bug Type: Bug
Bug description:SoapClient - Bad performance - Too many reassembled tcp packets
Description:
------------
I upgraded from Fedora 25 to Fedora 26, and thus my php was upgraded
form 7.0 to 7.1.8-1
I have a:
1) A web service written in C# with WCF, running under my Windows 7
development machine.
2) A php page that uses SoapClient to connect to my WCF service, running
under the Fedora Server with apache.
The call to the WCF service generates a xml file of around 400KB.
With Fedora 25 & PHP 7.0 this call generates around 17 reassembled tcp
packets, and it finishes in less than 1 second.
With Fedora 26 & PHP 7.1, the same call, generates around 250
reassembled tcp packets, and it needs around 10 seconds to finish.
I see a lot of TCP Out-of-Order warnings in wireshark. The other TCP
params (window size, scaling factor, ...) seem to the same.
WSDL cache is running (if i disable it the performance is even worse).
I reverted back to PHP 7.0 and the performance is normal again.
