It looked like like Gnus failed when sending my reply the last time, so
sorry if this post comes twice.

Try this:
# -*- cache-long-scans: nil; -*-
# This makes forward-line much faster and thus org-goto-line and
# thus org-table-sum (C-c +)

My org file is 9990 lines and I just do weekly summations on small
tables used for invoices. The performance was driving my crazy but
setting cache-long-scans to nil has made me happy again.

Best regards,
Jacob
