FEATURES

ProBalance ProBalance is our famously efficacious algorithm to maintain PC
responsiveness during high CPU loads. CPU Affinities Set permanent CPU
affinities so that processes run on the desired set of CPUs every time they
launch. CPU Sets A ‘softer’ form of CPU Affinities that are more like preferred
cores. Priorities Set permanent priorities so that processes run with them every
time. Efficiency Mode Control and persist Windows 11’s Efficiency Mode, which
designates processes as not performance critical to help keep them out of the
way. Disallowed Processes Immediately terminate any matched process, by your
criteria. Limit Instances Limit the number of instances a process may have in a
user session. Instance Balancer Spread CPU cores among running instances of
application(s). CPU Limiter Dynamically, temporarily limit CPU utilization of a
process when it reaches a threshold. Group Extender Enable processor group
unaware applications to make full use of the CPU. Power Profile Automation
Switch power plans while idle (IdleSaver), or when specified process(es) are
found running, or by a manual timer (Keep Awake), etc… Prevent Sleep (Keep
Awake) Process Lasso can prevent your PC from sleeping for a specified amount of
time, or when select processes are running. Disable Hyper-Threading or SMT
Dynamically disable Hyper-Threading or SMT on a per-process basis. Advanced
Watchdog Rules Create advanced rules to perform a specified action when matched
process(es) reach a certain threshold of resource consumption or other criteria.
Multi-select Operations Perform an operation like terminate on multiple
processes at once! Configuration Profiles Profiles allows for creation and use
of multiple rule configurations. More… Process Lasso contains numerous other
features and functions. Explore them for yourself!

ABOUT PROCESS LASSO

Process Lasso is Windows process automation and optimization software. From
tuning algorithms like ProBalance to user-created rules and persistent settings
such as CPU affinities and priority classes, Process Lasso gives you complete
control over running applications!


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 15.0 – REGISTRY ENFORCED PRIORITIES

This exciting release of Process Lasso introduces Windows registry-enforced
priorities! These enable priorities to be set on inaccessible processes, such as
those protected by anti-cheat systems.

PROCESS LASSO 14.2 – IMPROVED CORE SELECTION

Process Lasso v14.2 enhances core selection in the CPU Affinity and CPU Sets
dialogs with new controls for selecting specific CCDs on AMD processors, among
other improvements.

PROCESS LASSO 14.0 – NAMED CPU AFFINITIES

Process Lasso v14 introduces named CPU affinities! These make it easier to reuse
common CPU affinities, such as a particular CCD or your fastest cores. No longer
will users have to manually select CPU cores every time they assign an affinity!

HOW TO KEEP PROCESSES OFF E-CORES

A common complaint with heterogenous CPUs such as Intel 12th+ generation is that
sometimes threads will be inappropriately scheduled onto the efficient (E)
cores. There are a number of ways to discourage or entirely prevent this
behavior, and in this guide we’ll go through a few of them.

PROCESS LASSO 12.4 – E-CORE ICONS AND MORE

Process Lasso v12.4 adds leaf (eco) icons to distinguish the E-cores, delayed
CPU affinity rules, and more! We’ve also updated our ParkControl app with new
heterogenous scheduling settings, and tuned the Bitsum Highest Performance power
plan to prefer P-cores. All this is part of our continuing mission to empower
users to run apps their way!

PROCESS LASSO 12.3 – EFFICIENCY MODE RULES

Process Lasso v12.3 adds support for Efficiency Mode, which is the way Windows
classifies processes as not performance critical. This facilitates more optimal
thread scheduling, such as to efficient (E) and performant (P) cores. Using
Process Lasso, this setting can be automatically turned ON or OFF every time a
process is run, directing the process to, or away from, E-cores and P-cores.

PROCESS LASSO 12.0 – POWER MODES, CPU UTILITY %, AND 3995WX

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.

PROCESS LASSO 11.1 – INSTANCE BALANCER AND TRANSLATIONS

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 11.0 – TREE VIEW AND GRAPH TOOLTIPS

This release of Process Lasso adds a processes tree view and more helpful graph
tooltips!

The tree view, now the default, provides a way to visualize the process
parent/child hierarchy. Many applications spawn child processes, resulting in
several same-named instances, thus this new tree view makes managing them
easier. It also helps with visualizing the state of the system and specific user
activity.

PROCESS LASSO 10.4 – CPU SETS AND ALDER LAKE

This exciting release of Process Lasso v10.4 adds CPU Sets and Intel 12th Gen
support! CPU Sets are a ‘softer’ form of CPU Affinities. Instead of a hard
contract, they are a suggestion of preferred CPU cores. The OS will try to abide
by a CPU Set, but has discretion to schedule outside the Set. CPU Sets may often
be a better choice than traditional ‘strong’ CPU Affinities.

PROCESS LASSO 10.3 – CONFIG PROFILE SWITCHER

Process Lasso v10.3 adds the Config Profile Switcher, special ProBalance
handling for SearchIndexer.exe, and much more!

PROCESS LASSO 10.2 – CORE WORK

Process Lasso v10.2 improves ProBalance, refactors foreground boosting, adds an
Internet Explorer restriction feature, supports Windows 11, and more.
