Not really. `helm-org-ql' uses cache that is invalidated by _any_ change
in buffer + updating cache only when results are queried. Performance is
much better compared with built-in Org solutions.

Also, there is `org-element-use-cache' doing more granular cache
invalidation. You can enable it and test the performance. It is not
really degraded (except some hard-to-catch bugs existing in the
org-element-cache code).

Best,
Ihor
