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.
