Clarification needed: the original title is “You can move !Unpin”, which is definitely more surprising!

Totally agree, my server should definitely be able to handle the load. But this is a WordPress install, which is definitely doing too much work for what it is when just serving the pages. I plan to improve on this!

My server struggles a bit with the load on the WordPress site. You should be fine just reloading. I will make sure to improve things for the next time!

To be frank, this is more of a pretext to understand what pipes and vmsplice do exactly.

Thanks a lot for the information! I was not quite sure what to look for in this case. I have added in note in the article.

That sounds like a good idea!

I'm not claiming it'll be faster! Additionally io_uring has its own set of challenges, such as whether it's better to allocate one ring per core or one ring per application (shared by some or all cores). Pre-sharing buffers has trade-offs too, particularly in application complexity [alignment, you have to be careful not to reuse a buffer before it is consumed] versus the efficiency of zero copy.

I am again getting the hug of death of Hacker News. The situation is better than the last time thanks to caching WordPress pages, but loading the page can still take a few seconds, so bear with me!

I'll write an article on the flamegraphs specifically, but to get the data, just follow Julia's article!

Could you clarify how are you testing the speed of the first example where you are not writing anything to stdout? Thanks.

For the first Rust program, where I just write to memory, I just use the time utility when running the program from zsh. Then, I divide the number of bytes written by the number of seconds elapsed. That's why it's not an infinite loop ;)

Thanks!

The mother forced herself to save by punishing herself if she did not.

The $2000 in the saving account was earmarked for the dowry, and she would not touch it. So, she had to save every month to pay back the loan to the bank. The longer she took to do this, the more interest she paid.

This is a kind of non-rational trick that some people use to "trick themselves into doing the right thing". This is like paying some random stranger $100 if you do not accomplish some task.

Well, some people in rich countries take out a mortgage and buy a house on similar grounds.

With the differences of:

1. Immediate use of the home 2. Collateral that can be taken back of the loan isn't repaid 3. Often the collateral gains in value over the duration of the loan 4. The interest rate on the loan is way lower than a personal loan or a credit card.

I mostly agree.

However, (3) is a bug that's just commonly encountered (hopefully temporarily) in some countries that restrict construction way too much at the moment. One can hope.
