GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1.put in login credentials in cli-longrun example php 
2.run php cli_longrun_example.php 
3.check top

What is the expected output? What do you see instead?

output works perfectly but cpu is at 100%

What version of the product are you using? On what operating system?
xmpphp .1 rc1 rev 70
Debian 4.0

ejabberd 2.0.1

3.6.3

It's fixed in SVN.  I suppose it's time for a new release.

Hi,

I saw one "5" (microseconds?) wait, if I'm not wrong... IMO it's not enough 
(70%-80% CPU load here). 
Something like (500) seems to reduce it to 10%-12% here.(better but not sure if 
one idle daemon should use 
more that 1% at all).

In any case, couldn't that be configured in some place instead making 
processUntil() to use that configuration?

Just IMHO, ciao :-)

Great news Fritzy.  Any ETA on the new RC?

I tried grabbing the latest from svn and it still had the same CPU usage 
problem.  I
found that by adding a usleep to __process() for a mini timeout, I was able to 
go
from 99% CPU to 0.2% CPU which is a heck of a lot better.

private function __process($maximum=0) {

    $remaining = $maximum;

        do {
                        usleep(100000);

Nice PaulSK.  Fritz, any official keeper comments?

I have found solution for me.

file XMLStream.php
new lines
    } else if ($maximum == 0) {
        $secs = 0;
        $usecs = 200000; // sleep for 200 miliseconds, if no data
    } else {

and in the my code
    $xmpp->processUntil(array('message'), 0.1);

Switching from 0.1rc2-r77 to svn dropped from 44% to 28% to 42%.  But my bot 
still
uses more processor than mythbackend while active(~10%).  

The php.net/stream_select page suggests 200000 microseconds to lower cpu usage. 
Patch attached for what I did.  I'm no longer at the top of top.  

Patch attached.  It's not perfect just my hack.
