Very slow on bootup and running on multiple devices

[catsgomoo]

I used method 1 and wrote an eve and pyro image using swtmp. Loaded it on a 64gb 3.0 pny flashdrive. It loads extremely slow on boot up and running. This is on a high end spectre laptop and a dell gaming laptop running intel chipsets. Would it run better if I did not use swtmp?

There's more to this than speed of your USB-stick. Depends on which port (not all devices allow booting from USB3.x ports, but also you've chosen a build that's not for your chipset. Pyro is for Lenovo 11" Education Chromebook based on Apollo Lake (Intel Atom). Eve is for Pixelbook, which runs KabyLake-Y (which is Core-M basically).

Check out: https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices to see if there's a base-board which closer matches the spec of Spectre/Dell.

Also; this question probably isn't for Croissant, but for Chromium-OS build. Croissant brings two builds together w/o checking for compatibility, that's your role :)

I'd also highly recommend using an internal SSD rather than a USB, because USB drives have limited write life and tend to be MUCH MUCH slower than even base level SSDs due to the widely varying drivers available for USB controllers, where SATA SSDs or M.2 SATA/NVME SSDs there isn't really a driver, the motherboard determines an operation mode (AHCI/Intel RAID/etc) and then the Linux kernel that ChromiumOS runs on top of just uses the drive as /dev/sdaX or /dev/nvme0nX and gets pretty good speeds out of the drive automatically, and the super crazy tweaking of blocksize and sleep intervals/etc require way more in depth knowledge and probably would need a lot of testing to figure out which ones actually help ChromiumOS and which ones hurt, and the infrastructure to automate that testing all lives inside Google.

Too slow, much much slower than Win10, use this OS is a nightmare.
