roadrunner: Performance degradation on production

PHP 7.3 / Symfony 3.4

Hi! On local dev server i get x 2-10-20 request time speed up for 1 concurrency request.

But on production for 50 concurent request performance on FPM 180 requests per second, on RR 165 rps. If add gc_collect_cycles() for each cycle - perfomance for RR down to 140 rps…

It is strange, there are ideas why it can work slower than FPM?

ab -n 10000 -k -c 50 ...

Enable/disablee keep alive; direct connect to roadrunner port or nginx proxypass do not affect performance.

config:

http:
  address: 0.0.0.0:8080
  workers:
    command: "php /var/www/app/current/worker.php"
  pool:
    numWorkers: 8
    maxJobs: 0

bin/rr serve -c roadrunner.prod.yaml

With numWorkers: 50 and maxJobs: 200 the same perfomance.

Processor: AMD Ryzen Pro 1700x (8 x 3,4 GHz) RAM: 32 GB DDR4

@wolfy-j you’re right. But I cannot show a commercial application having a problem. Making a special fake application to demonstrate a problem is too much work. The employer will not pay for it.

Perhaps a problem with some kind of PHP-module or open-source library. Now I can only provide this data.

@wolfy-j Actually, this is not correct anymore. From last year, Symfony is supporting long-running mode without memory leaks via kernel.reset tag. 3rd party bundles; hard to say.

But for some time, and still unknown reasons, I get insane amount of memory used on blank project. When I played with swoole recently, memory leaks happened during conversion to Symfony request: https://github.com/k911/swoole-bundle/issues/30

If interested, tomorrow I can start RR test on blank Symfony project and report you the details. It is the same problem; memory went wild during conversion. Code I used for RR test:

$kernel = new Kernel($env, $debug);
$relay = new StreamRelay(STDIN, STDOUT);
$psr7 = new PSR7Client(new Worker($relay));
$httpFoundationFactory = new HttpFoundationFactory();
$diactorosFactory = new DiactorosFactory();
$kernel->boot();
while ($req = $psr7->acceptRequest()) {
    try {
        $request = $httpFoundationFactory->createRequest($req);
        $response = $kernel->handle($request);

        $psr7->respond($diactorosFactory->createResponse($response));
        $kernel->terminate($request, $response);
//        $kernel->reboot(null);
    } catch (\Throwable $e) {
        $psr7->getWorker()->error((string)$e);
    }
}

@wolfy-j do you expect activity from me? I suspended the research because roadrunner is worse than fpm + nginx.
