I got around it by removing the default seeders by specifying an empty =
seeders list since we don=E2=80=99t need the MARKUP annotations anymore.

I still don=E2=80=99t know why it created so much overhead but it =
sometimes seemed to rival the POS tagger in processing time.

Anyway, this leads me to the next question. Can I disable the creation =
of Ruta basic annotations entirely to save processing overhead and only =
apply Ruta rules to other annotation types created by other AEs such as =
our own?

Cheers
Mario
