--- Comment #22 from Tor Lillqvist <tml at iki.fi> ---
I have been looking at the delay after typing the first character in Writer in
a LO session. Seeing this requires having a LO built with --with-myspell-dicts
(for typical developers, no idea what it requires for people using end-user
packages).

It is the LightProof Python code that causes most of the slowness.

Here is the "Heaviest Stack Trace" from the TimeProfiler tool in Intruments on
macOS, slightly edited. The number after the dylib name is in milliseconds. One
can see that the first call to pyuno::Adapter::invoke() takes about 300 ms.
(And some temporary SAL_DEBUG output confirms.)
