AdBlocker Ultimate for Windows version 4.1 introduces multiple performance and efficiency improvements.
Completely revamped ad-filtering engine
The ad-filtering engine was completely rewritten from scratch. The effort produced 7-8x faster loading of filter lists by utilizing algorithms for lazy loading of rules. There is no need to maintain all rules in memory if we are not going to use all of them.
The software will cache the rules that are most frequently used. This results in even faster rule matching (quicker web page filtering).
AdBlocker Ultimate now takes advantage of Windows’ efficiency mode API. This will decrease system resource usage and will improve energy consumption (great news for laptops!).
Lower memory usage
Thanks to the optimizations above the memory usage was drastically reduced. Only resources that are actively in use are readily available.
