verry slow performance when activate tp

Hello there,

Our plugin needs to parse the entire HTML of a page in order to serve translations, so it can be memory intensive.
But it usually doesn’t impact speed loading times and you can also cache translated pages, in which case they shouldn’t be processed by PHP at all.

We recommend you use a caching plugin. Cached pages are not processed on every page load. TranslatePress can be resource intensive with large pages, but it depends on how much HTML content there is on one page.

Automatic translation will slow the page down on the first load, so the PHP will wait for the translations and then show the page. This only happens once or if you add/change strings.
Also, we have a article that explain pretty well how TranslatePress differs from other translation plugins based on loading speed: https://translatepress.com/top-wordpress-translation-plugins-compared-based-on-page-load-time/

Could you check if you have duplicate entries in your database? You can use the Remove duplicate rows option from TP Settings –> Advanced tab to clear them.
Otherwise, try to disable the gettext translation.

One reason may be that you could have many gettext strings translated on your site. Download and install this mini-addon https://translatepress.com/docs/developers/disable-translation-of-gettext-strings/ then try again.

Best regards,
Cristian

Hello, i use this plugin too, it worked very nice, but after upgrading to 1.9.5 it performs very slow, about 5x slower than usually. Now i restored version to 1.9.4 and it works fast again. Something is bad in 1.9.5 version.
