WEXAL® Page Speed Technology (hereinafter referred to as "PST") Manager has three modes for increasing the display speed of web pages.
1. Smart-mode
2. Expert-mode
3. Developer-mode
* Refer to the "PST Manager Manual" for details on how to set each mode and control PST.

Based on the settings for "Resource Optimization", "Remove Optimized Resources", and "Optimization Strategies", Strategic AI "David" will automatically generate and execute strategies.
The "Resource Optimization" settings allow you to change the types and paths of resources you want to exclude from resource optimization, as well as the compression level of images. The "Remove Optimized Resources" setting allows you to delete optimized resources by specifying the time period and/or the resources.
In Smart-mode, 4 types of directives can be configured: lazy load, proxy, webfont, and engagement delay. Note, only exclusions can be set in the advanced settings for engagement delay.
