[Resolved] Performance issue with WPML 3.5 and 3.5.1

WPML 3.5 was released with major performance improvements regarding handling of strings in the string translation plugin. In that version, we created a separate table that helped with the strings, by caching them and thus speeding-up the performance of the sites.
However, this created a problem with the size of the table, so we released a new version - that further improves the speed of your site - WPML 3.5.1 - and this version uses two separate tables.
With two tables, we are able to limit the size of the table -> by more efficiently creating the cache of the strings.

This brings us to the current issue.

Currently, there might be some issues because we mistakenly created additional index in one of the two tables that we created, and we need and use only one.

This leads to some performance issues, growth in queries and growth in table size - because of the index size.

Our developers are aware of the issue and they are working now on a fix for this.
We are ready to test that fix in production on our site - wpml.org and after it passes tests, we expect that the performance would be greatly improved and the table size to be with a proper size.
After our tests, we expect to release very soon a new official version that fixes this problems.
