Is it possible to use text2pcap in kernel module?

Not without putting it and the code it uses to write a pcap file (which isn't from libpcap, it's from a small library that's part of Wireshark, also used by dumpcap to write pcap and pcapng files) into the kernel.

How can I save an output as pcap file while being in kernel module?

You could write your own code to open a file and write to it in the kernel module; "Writing to a file from the Kernel" talks about that.

It also says

A "preferred" technique would be to pass the parameters in via IOCTLs and implement a read() function in your module. Then reading the dump from the module and writing into the file from userspace.

so you might want to consider that; the userspace code could just use libpcap to write the file.

After searching a good deal regarding nikic/FastRoute post request, stumble upon this stackoverflow post. After that have made the following changes to the code.

In Bootstrap.php, getting (get()) HttpRequest/HttpResponse instances, instead of making (make()) them, solved the problem.

composer info won't give you that information.

The easiest way would be to get it from composer.lock directly. Instead of writing your own parser, you could use a ready-made tool like jq.

After downloading it you could write an expression like this one:

Yes, Wrk is one of the most respected benchmarking tool but you can not tell you boss that your application will handle 176,000 requests/second

because there will be some added conditions which will reduce the application performance. To get the correct benchmark score you can test by replicating all those conditions on your development environment and try benchmarking.

Conditions like

1. Database Connection (if Application is using Database)
2. Server Configuration
3. Reverse Proxy from your HTTP Server (i.e. Nginx or Apache) Very important
4. And other application-specific conditions

Is because you're not specifying a class instance (object) but the class itself.
Try to instantiate a new object with new $class().

When you're using variables as class name (like new $class), they need do contain full qualified name. In your case $class contains Controller while FQN of this class is Controllers\Controller.

One must use the fully qualified name (class name with namespace prefix). Note that because there is no difference between a qualified and a fully qualified Name inside a dynamic class name, function name, or constant name, the leading backslash is not necessary.

You need to put FQN in your dispatcher config:

I take it that new RequestHandler($container); is also from Relay, which uses the container for resolving requests as a middleware but does not pass it around otherwise because it would be a service locator.

1. Quick clarification about "using" the container in classes.

Rather than trying to pass the container to the classes, use the container to inject each class with its dependencies, ideally with type-hinting.

For instance, if you want to use that logger in a class, it should not be through $container->get(myLogger::class). Instead, something like this:

try creating an alias first and then provide it to a factory
