PHP Bug Type: Performance problem
Bug description: Soap Call causes CPU to go 100%
Description:
------------
We've been using soap for a while now and noticed that when we send a soap
request and it waits for a response, PHP goes in a sort of loop and takes
CPU load. Our average waiting time is 4 seconds.
A soap call once in a while is ok, because it doesn't take too much CPU
overall. But we noticed that the more we grow, the more CPU it takes, to a
point where we reach often 100% CPU if we do a loop of soap calls. (All
that caused by the waiting time of the soap call!!!).
Reproduce code:
---------------
x
Expected result:
----------------
Would it be possible that PHP goes into an idle mode when it waits for a
soap response instead of taking all the CPU ressources?
Actual result:
--------------
CPU goes crazy when we do too many soap calls in a row (we can do maximum
of 4 soap calls at once, else it would overload the server).
