On my machine, GCL takes 2.4 seconds to load "draw". But it uses an older
version of GCL, namely 2.6.14. Maybe the "slowness" was introduced with
2.7.x.

I could confirm that GCL 2.6.14 too is quite slow in reading files. Reading
a 50 MB file took more than 4 seconds on a lightning fast NVMe SSD with ZFS
and a huge cache on top.
