Hi,

I've recently tried to upgrade to 5.1 on a WP 2.0.5, but had to deactivate. All pages (including non-translated) pages were taking about a minute to render. Even non-translated pages. When I deactivate everything is back to normal of about 3 seconds for page render.

Any ideas on how to fix?

Hi Todd,
Translator plugin increases the content on your site by 13 (14) times which causes lot of extra spidering by search engines as well as human traffic. All of these increases the load on your server.

Translator plugin uses caching to improve performance. A page once translated is kept in cache, which is intelligently refreshed based on a sophisticated algorithm.

You can further improve MySQL performance of the plugin by adding some indexes to your database.
Go to Options->Translator->Advanced->Miscellaneous and read the Optimize Translator Page Cache Table section. Run the queries specified therein using MySQL command line or phpMyAdmin. They will significantly improve database access time.

By the way, Translator has nothing to do with non-translated pages. So, after this, if you still get slow loading pages, it has something to do with any other issue.
