[Closed] WPML causing really slow backend pages (when saving pages)

Hello,

1/ Our wp_icl_translate table is heavy (269 MB). The heaviest of all our DB tables. Followed by the wp_icl_translation_status table (235MB). Is there a way to lighten them up? Please advise.

2/ When I run the following SQL query in PHPMyAdmin :
SELECT * FROM wp_icl_strings WHERE status = 0;
I get 33,366 results (out of 82,264 total entries in the table). Looks like quite a lot, no? Any point in deleting these “ghost entries” with:
DELETE FROM wp_icl_strings WHERE status = 0;

3/ And last but not least: we’re experiencing seriously slow backend pages load times (especially while saving/publishing posts, which we do dozens of times single day). Apparently, WPML would be responsible for it. Some errors lead to using all of our server RAM resources (and we have the best setting our hosting provider can offer), which ultimately causes DOWN times)

Any thoughts?
Thanks in advance.
