Our novel ProBalance algorithm helps maintain system responsiveness during high CPU loads by dynamically adjusting the priorities of running programs to keep problematic background processes in check. With ProBalance, no longer will single, or multiple, processes be able to bring your system to a virtual stall. Process Lasso will let you keep interacting with your computer, even when it is under a heavy CPU load. Try our CPUEater Demo to experience ProBalance for yourself.
Process Lasso also allows users to automate and tweak how applications are run through a number of unique and helpful functions. These include persistent priority classes, persistent CPU affinities, disallowed processes, per-process power profiles, a process watchdog for advanced rules, process instance count limits, multiple instance balancing and much more!
Process Lasso is the ultimate Windows CPU affinity changer. The CPU affinity specifies the set of CPU cores an application is able to execute on. With Process Lasso, you can control this with a persistent setting that applies every time the application is run, or change it dynamically while the application is running once a threshold is met. The CPU affinity is commonly changed to limit CPU use or improve performance.
Many additional functions such as power plan automation, a system responsiveness metric and process activity logging are also available.
These features give you the ability to control how programs utilize your computer’s resources based on automatically applied settings. With Process Lasso, you can decide exactly how you want your processes to run.
For minimal resource use, all algorithms and process rules are enforced by a stand-alone background service called the Process Governor. The GUI is entirely optional.
Betanews on ProBalance:
Process Lasso’s headline technology is ProBalance, a smart tool which monitors running processes and intelligently adjusts the priority of resource hogs as they appear.
Can this really make a difference? We used the developer’s “CPUEater” demo to create a process with 48 active threads, and tried launching Chrome (with its core files cached). It took 30-40 seconds to appear with ProBalance disabled, under 1 second with it turned on.
That was a very extreme example, so we tried again with 16 threads (one per core), and Chrome loaded in 5 seconds; 8 threads and it loaded in around 2, still more than twice the ProBalance-enabled time.
We tried a few other CPU-stressing apps with similar results. If you’re running multiple applications at the same time, and something tries to hog your CPU, then Process Lasso’s priority tweaks generally mean your system stays very responsive.
Process Lasso v12.3 adds support for per-process Efficiency mode, a native Windows 11 feature to designate processes as not performance critical. Using Process Lasso, this setting can be automatically applied every time a process is run.
Process Lasso v12.0 adds support for Power Modes, new processor topologies (3995WX), and changes the default CPU use metric to CPU Utility %. ParkControl v3.0 was also released with Power Mode support and UI improvements.
This release extends the Instance Balancer feature, improves translations, and further polishes the v11.0 release last month.
Process Lasso’s Instance Balancer is commonly used to spread multiple instances of an application over the CPU, giving each instance a dedicated set of CPU cores. It can also be used to spread distinct applications across the CPU using advanced process match patterns.
Process Lasso is available in English, German, Russian, Slovenian, Spanish, Polish, Finnish, PT-BR, Japanese, and Chinese (Simplified and Traditional). Help translate Process Lasso.
