Hello all,
If I run the following document on a 8 GByte RAM Linux machine.
It takes more than 30 minutes until luaotfload has build
the cache for Sparks-Dotline-Medium.otf. If I run another
Program in the background that it never ends (too less memory).
On my Mac the first run with context (upcoming TL2019) needs 9.5 Gbyte
memory and nearly 100% CPU load to scan the Sparks-Dotline font.
This one is, of course, 400 kB big, but why do we need
more than 8 GByte Ram??
The font files are here:

- the cpu load is puzzling: assuming that you have multiple cores,
luatex will only use one core
- the 30 min on linux is probably due to swapping
- the 8 gig in general is a side effect of the way this font is using
pair positioning (half a billion pairs due to classes where most pairs
are dummies)

i hacked a faster solution for such fonts (now I need some 25 sec for
the initial caching so probably less on your machine and < 0.1 sec for
loading the cached font)

These make a pretty good case for using proper drawing package,
