Phalcon\Mvc\Micro->mount performance issues

Most of the time on production result of all mounts could be just cached, and instead of mounting them you could just set handlers. Extend phalcon micro and add such functionallity yourself, simple as that.

For optimizing handle - there is no way around this currently for yourself, well you can always just write new router for phalcon if you want :)

Can you give a simple example?... I'm not quite sure how to just set the handlers...

class YourMicro extends Micro
{
    public function setHandlers($handlers)
    {
        $this->_handlers = $handlers;
        return $this;
    }
}

Somewhere in your code:

$micro = new YourMicro();
$cachedHandlers = $di->get('cache')->get('cached_handlers');
if (empty($cachedHandlers)) {
    // do all the mounts here
    $di->get('cache')->save('cached_handlers', $micro->getHandlers(), 0);
} else {
    $micro->setHandlers($cachedHandlers);
}

Not sure why phalcon doesn't provide setter.

Getting this error when saving via $app->persistent->handlers = $app->getHandlers();

Found this thread https://forum.phalcon.io/discussion/16895/routing-performance-in-micro-app

Describes the same issues as here. And routes can't be cached because of lazy instantiation...

Well you could try https://github.com/jeremeamia/super_closure

Thanks i'll try! I'll circle back when i've tried it

Though this is exactly why i wrote there it might be actually a slow, well i forgot to mention there that i mean caching routers with closuers, that you need to use 3rd party. Atually if you have router without closuers it might be faster. You could eventually try not use lazy and then caching if you don't care about memory.

Still says:

And using https://github.com/jeremeamia/super_closure is way too slow, serializing/deserializing all controllers (has to be a closure)

You sure that those controllers doesn't have any closuers somewhere? You need to just find where you have closure in this code and try to refactor it somehow.

Also don't use persistent for this, use cache.

Also i forgot to mention but you also need to use $this->router->getRoutes() and cache them as well since mount is also adding route objects.

Caching handlers now work next error i get is:

[05-Sep-2018 21:48:02 Europe/Copenhagen] PHP Fatal error: Uncaught Phalcon\Mvc\Micro\Exception: Matched route doesn't have an associated handler in /Users/AndreasAagaard/PhpstormProjects/QuickOrder - Api/api/v8/public/index.php:57

So when the routes is cached what do i do in the else: block? Where ->setHandlers is called

Yea i wrote you above also that you need to cache routes. Handlers are just handlers, routes are routes.
