By hosting your site in the Servebolt Cloud you can fix PHP Workers issues, because Bolts come with an unlimited amount of PHP workers on all hosting plans.
Servebolt builds and maintains custom versions of PHP, that implement optimizations that allow the PHP to be processed faster. All Bolts on Servebolt also have PHP opcache enabled, to further accelerate processing time.
