By default Linux distros are unoptimized in terms of I/O latency. So, here are some tips to improve that.

Most apps still don't do multi-threaded I/O access, so it's a thread-per-app which makes per-app speed always bottlenecked by single-core CPU performance (that's not even accounting for stuttering on contention between multiple processes), so even with NVMe capable of 3-6 GB/s of linear read you may get only 1-2 GB/s with ideal settings and 50-150/100-400 MB/s of un/buffered random read (what apps actually use in real life) is the best you can hope for.

All writes are heavily buffered on 3 layers (OS' RAM cache, device's RAM cache, device's SLC-like on-NAND cache), so it's difficult to get real or stable numbers but writes are largelly irrelevant for system's responsiveness, so they may be sacrificed for better random reads.

The performance can be checked by:

• `fio --name=read --readonly --rw={read/randread} --ioengine=libaio --iodepth={jobs_per_each_worker's_command} --bs={4k/2M} --direct={0/1} --num

Steam Client on APFS Case Sensitive Mac OS Drive

If you are using APFS Case Sensitive File system and trying to use Steam, it will flicker & silently fail or show the following error message:

steam requires that '~/library/application support/steam/steam.appbundle/steam/contents/macos' be on a case-insensitive filesystem.

To fix the issue, follow the instruction here.

Run from your user account, NOT ROOT!

#!/usr/bin/env awk -f
#
# AWK script to send multiple `sendkey` commands to a QEMU virtual machine.
# It writes at a rate of roughly 40 keys per second, due to lower delays
# resulting in garbage output.
#
# It makes use of a TCP client created by an external utility, such as OpenBSD
# Netcat, to interact with QEMU's monitor and send a stream of `sendkey`
# commands. This is a practical way to transfer a small file or to script
# interactions with a terminal user interface.
