Yeah, detected the issue. 

Configurations were the same for all installations (default configuration), so this issue
doesn't relate to the output buffering. Just to be sure, I have compared output for "php
-i" for all installations, there were only differences in REQUEST_TIME, build version and ...
presence of loaded php.ini file for PHP5.4.10. 

If php.ini file is present (settings are still default) and loaded, then speed of method invocation
is higher... Amazing ) Without php.ini (but with the same default settings) speed is lower for
internal development server.

This can be reproduced with PHP5.4.10 too. So this performance bug is more general.

I can not reproduce this, do they (5.4 and 5.5) share the same php.ini configure?

I think maybe due to output buffer.

Update PHP version for issue manually (There isn't alpha3 in select).

Description:
------------
I notice, that speed of method invocation for PHP5.5.0alpha3 is significantly slower than for PHP5.4
when running the script with internal Development Server. However, for CLI-mode PHP5.5.0 is faster
than PHP5.4.10, as expected.

To reproduce the issue, please start the development server and execute test script in the browser.


Test script:
---------------
class TestPerformance {

    public function speed()
    {
        $time  = microtime(true);
        $this->nop();
        echo 'Took ', sprintf("%0.3fms to call method", (microtime(true) -
$time) * 1e3);
    }

    protected function nop() {}
}

$instance = new TestPerformance;
$instance->speed();

Expected result:
----------------
Expecting that method invocation will take microseconds to finish:
php-5.4.10-Win32-VC9-x86:
  Took 0.005ms to call method
php-5.5.0alpha3-Win32-VC9-x86:
  Took 0.00Xms to call method

Actual result:
--------------
Method invocation for 5.5.0alpha3 took millisecond to finish:
php-5.4.10-Win32-VC9-x86:
  Took 0.005ms to call method
php-5.5.0alpha3-Win32-VC9-x86:
  Took 1.008ms to call method
php-5.5.0alpha3-nts-Win32-VC9-x86:
  Took 1.000ms to call method
