@Tom_Booth Just in case you’re not doing so already…
Instead of writing/reading everything yacy does to the livestick’s storage space; Perhaps a ramdisk/tmpfs (+ some nifty symlinking at boottime, of certain things perhaps not needing to be persistant) could be a beneficial thing? For both speed of operation, not to mention towards longevity of the flashstick?
And having (at least a bit of high-priority, if not all of it) swap at a zram might also be beneficial, instead of swapping to the flash:

Though this of course hinges on the amount of ram available on the thingy the stick get’s stuck into
