WEBO Site SpeedUp for WordPress is an ideal solution for your website performance optimization. It allows you either to easily tune website load speed after all major plugins are installed, or to change configuration after adding new (or removing old) ones.
Average website acceleration is 2.5-3x (for example for Halfway to Concord website it was 2.8 times). And this result (due to reduced server side costs to generate pages, reduced number of HTTP requests, and static gzip applied) leads to significantly increased website uptime and its ability to handle much more visitors every day, every hour, and every second!
