man pmset
OK, so RTFM jokes aren't funny anymore. Specifically, what you're looking for is to change the hibernation mode. Old macos used to keep the RAM powered during sleep, so there's a slight drain on the battery, and if it runned out, well state was lossed. BUT the upshot was that wakeup was instant.
As it turns out, that's the default mode on desktop. And you can set your laptop to do that too (assuming you're ok with the tradeoff).
sudo pmset -a hibernatemode 0
Here's the relevant section from the man page:
hibernatemode supports values of 0, 3, or 25. Whether or not a hibernation image gets written is also dependent on the values of standby
and autopoweroff
For example, on desktops that support standby a hibernation image will be written after the specified standbydelay time. To disable
hibernation images completely, ensure hibernatemode standby and autopoweroff are all set to 0.
hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The system must wake from the con-
tents of memory; the system will lose context on power loss. This is, historically, plain old sleep.
hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the disk), and will power memory
during sleep. The system will wake from memory, unless a power loss forces it to restore from hibernate image.
hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove
power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery
life, you should use this setting.
