Topic: Kernel and IO
|

--------------------

|
|
|
|
Background: Asynchronous IO
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
- https://www.kegel.com/c10k.html[The C10k problem]: a very frequently quoted (and actually
|
|
quite old page (2003-2011) that analyses the problem of serving more than 10k requests from a server,
|
|
the bottlenecks and possible solution strategies.
|
|
- https://dreamsongs.com/WorseIsBetter.html[The crux with »worse is better«]. This is a summary
|
|
by Richard P. Gabriel himself, looking back, and he still has not made up his mind if _worse is better_.
|
|
The tension between the »*Berkely*« (or »New Jersy«) style and the »*MIT* style« helps to understand
|
|
design choices taken in the original design of Unix -- and with the advent of fast SSDs and finally
|
|
an interface like `io_uring` in the Linux kernel, all these unresolved questions are coming back
|
|
to haunt us.
