Compile Stress Test 2019-10-03
rust

This is an experiment in blogging. I am going to be putting my tweets and select replies one after another without commentary.

shitty synthetic benchmark idea: how long it takes for a compiler to handle a main function with 1.2 million instances of printf("hello, world!\n") or similar

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 2, 2019

fun fact, you need an AWS x1.16xlarge instance to compile 1.2 million lines of rust source code

oh god that might not be enough

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 2, 2019

oh god, is that what X1 is for???

My wallet just cringed.

TFW rust uses so much ram an x1.16xlarge can't compile hello world

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 2, 2019

Let's go x1e.32xlarge!

Rust can't match V for compile performance

Finally can run two electron apps.

It stopped growing at 2.66 TB of ram!

overheard: "im paying this computer minimum wage to compile this god damn rust program"

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 2, 2019

The guy who's paying for the instance in slack said it

you magnificent cursed unholy monster

Just a simple rust program, only 9.88090622052428380708467040696522138519972064500917... ร— 10^361235 possible conditions

Normal couples: watch tv together or something

me and my fiancรฉ: watch someone try to compile a 1.2 million line of code rust function over slack

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 3, 2019

I guess #rust isn't production-ready, it can't compile hello world.

SURVEY SAYS:

memcpy()!

โ€” Cadey Ratio ๐ŸŒ (@theprincessxena) October 3, 2019

01:01 (Cadey) dalias: this is basically 1.2 million instances of `printf("hello, world!\n");` in void main
01:01 (dalias) wtf

"back to 1.47T ram"
"oh no"
"1.49"
"oh it stopped"
"it's definitely still in mir dataflow"

"what stage is that?"

โ€” Jaden Weiss (@CompuJad) October 3, 2019

Lol it ran out of memory!

4 TB of ram isn't enough to build hello world in #rust!

Meanwhile the same thing in Go took 5 minutes and I was able to run it on my desktop instead of having to rent a server from AWS.
