Before nginx was a thing, I worked with a guy who forked apache httpd and wrote this blog in C, like, literally embedded html and css inside the server, so when he made a tpyo or was adding another post he had to recompile the source code. The performance was out of this world.
Does a file lookup really take that long? Id say the trick was to have just plain old html with no bloat and you’re golden.
Blog content was stored in memory and it was served with zero-copy to the socket, so yea, it’s way faster. It was before times of php-fpm and opcache that we’re using now. Back then things were deployed and communicated using tcp sockets (tcp to rails, django or php) or reading from a disk, when the best HDDs were 5600rpm, but rare to find on shared hosting.
Couldn’t the html be loaded into memory at the beginning of the program and then served whenever? I understand the reading from disk will be slow, but that only happens once in the beginning.
There are plenty of sins people still commit and can commit when it comes to web development. Reading from disk is not the bottleneck. If site is slow most likely it’s not the disk read times, database access or anything similar, but silly code that generates the page. It’s almost always the code generating the page that’s at fault.
The answer is no. The more file is used the longer it sits in kernel filesystem cache. Getting file from cache versus having it in process memory is few function calls away all of which takes few microseconds. Which is negligible in comparison to network latency and other small issues that might be present in the code.
On few of our services we decided to store client configuration in JSON files on purpose instead of running with some sort of database storage. Accessing config is insanely fast and kernel makes sure that file is cached so when reading the file you always get fast and latest version. That service is currently handling around 100k requests a day, but we’ve had peaks in past that went up to almost a million requests a day.
Besides when it comes to human interaction and web sites you only need to get first contentful paint within one second. Anything above 1.5s will feel sluggish, but below 1s, it feels instant. That gives you on average around 800ms to send data back. Plenty of time unless you have a dependency nightmare and parse everything all the time.
Ah, you met fefe.
Fefe uses a LDAP server as backend, not Apache
He also uses his own http server that in turn queries the ldap server solely for the articles. The rest is compiled into the http server binary.
Nothing good old cache can’t solve. Compile JS and CSS. Bundle CSS with main HTML file and send it in batches since HTTP2 supports chunkifying your output. HTTP prefers one big stream over multiple smaller anyway. So that guy was only inviting trouble for himself.
You’re telling me about compiling JS, to my story that is so old… I had to check. and yes, JS existed back then. HTTP2? Wasn’t even planned. This was still when IRC communities weren’t sure if LAMP is Perl or PHP because both were equally popular ;)
Am just saying including source code into Apache is an overkill. But I guess if Apache was so old that doing so wasn’t much of a chore, sure thing. Still think apache module would have been simpler.
What if, get this, we put the bash scripts in yaml. And then put it in kubernetes.
well now you’re just describing ansible
Have you considered embedding python in those bash scripts? I have done this, and it is glorious.
I wrote my webserver in pure bash.
bash -c “python -m http.server 8080”
Did you know you can zip entire Python project into single file and make it executable? Quite a neat feature. Shove all dependencies, modules and assets in there and voila. Single file python application.
PIGZ is an incredible standard
This is false, you also need vim and tmux
Idk about you but I use echo and sed to edit my files.
Let’s just get this out of the way
Microsoft Word is the only text editor I need.
I think you mean edit for ms-dos.
One Note
A Notebook
I’m currently trying to relearn all my advanced bash in python.
i already learned how to use my operating system, now you’re telling me I have to learn 30 new libraries that do the exact same shit?
Just for fun or do you have a specific thing you feel would be better in python?
Certain things I want to do will be easier in python and will be more portable. But bash is my home.
Fair enough. The line for me has always been whether or not I expect to use it for more than just glue or a one off run
I feel like this with Python these days.
Never sed when you can bash.
All you need are Bash scripts with chroot and cgroups and some ssh access.
The dude on the right is some neckbeard who yells “RTFM” and “i use Arch btw ;)” IRL.
wow
99% and maybe even 100%
