Mine is painful for storage. The eMMC is the most painful part. I can deal with low memory, I can deal with the cpu, but read and writes are painfully slow. I am using fedora cosmic atomic and it works better than most. Look up how to tweak reads and writes for eMMC if you have it, you can help speed it up.

I’ve also had a slow eMMC chromebook once. adjusting I/O caching helped noticeably: # /etc/sysctl.d/20-flash-speed-settings.conf # disk-settings # https://lonesysadmin.net/2013/12/22/better-linux-disk-caching-performance-vm-dirty_ratio/ # (vm.dirty_background_ratio = 10) percent of memory to use for caching vm.dirty_background_ratio = 15 # (vm.dirty_ratio = 20) the max percent of memory to use for caching vm.dirty_ratio = 30 # (vm.dirty_writeback_centicecs = 5) how often the buffer is checked for work to do vm.dirty_writeback_centisecs = 6000 # (vm.dirty_expire_centisecs = 500) sets how long something can be in the buffer vm.dirty_expire_centisecs = 6000

U wonder if reading from the ports is any faster?
