wordpress site too slowly work with plugin qTranslate X

qTranslate-X is known to have a significant impact on a site performance. Unfortunately, it is kind of unavoidable and there is not much you can do right now, except getting a more powerful server.

You may try tuning option “Translation of options” on page “/wp-admin/options-general.php?page=qtranslate-x#advanced”. Depending on the complexity of your site it may give you some boost, probably not much, but it is the only thing which currently can be customized for the performance sake.

We are aware of the problem and performance is hopefully improving with each release, but there is a lot more to do to improve it further.

Thank you for your input, much appreciated.
