navigating through the locales.json file was slow (at some positions)
before the change and is now reasonably fast (but alas not
instantaneous).
Which navigation commands were slow, as compared to the same commands in
other portions of this file?
For example C-p, C-n, C-v, M-v. C-f and C-b also, but much less so.
For example, open the file and do M-g c 70000 RET. This took about 5
seconds. Now do C-n, this again took about 5 seconds. With the
optimizations, M-g c 70000 RET is almost immediate, and C-n there takes
less than a second.
But you're right, this slowdown has little to do with bidi. A file with a
sufficiently long single line of Arabic text has the same problem. (But
not one with a line of Hebrew text.)
