Process Lasso by Bitsum

Process Lasso is a process optimization and automation utility with a unique new technology. That will improve your PC’s responsiveness and stability during periods of high CPU load. Priority optimization, affinity optimization, automated rules, you name it and Process Lasso has it.

Process Lasso’s unique technology called ProBalance (Process Balance) will improve your PC’s responsiveness and stability through process priority optimization. Windows allows programs to monopolize your CPU without sufficient restraint. It leads to hangs and micro-lags.

ProBalance intelligently adjusts the priorities of running programs on-demand. So that badly behaved processes won’t negatively impact the responsiveness of your PC. It does this not by raising process priorities, but instead by temporarily lowering the priorities of background processes that may be interfering with foreground responsiveness.

This utility also offers an assortment of ways to take full control of how your CPUs are allocated to running programs.

In essence, Process Lasso is an all-in-one automated Windows process tuner. You can choose at what priority processes should run, and which CPUs should be assigned to them. In addition, you can disallow certain programs from running, log all programs run, automatically restart programs, limit the number of instances of a program, and much more. You can even indicate processes that should induce entrance into the High Performance power scheme or prevent the PC from sleeping. A gaming mode also allows for easy process priority optimization for avid gamers.

Process Lasso is the ultimate companion to servers of all types. For Terminal Servers it can help ensure no user monopolizes the CPU. For all types of servers its ProBalance algorithm can improve responsiveness. Furthermore, the automated process control can allow you to tweak running processes in ways never before possible.

    This program is fantastic for managing resources on low powered computers, but the price is quite high, and the license is valid for only 1 year. I'm using an old non-upgradable giveaway and will probably buy it when a reasonable offer appears.

    All this program does is play with your system resources. If your running a lot of programs in the background and then you launch a new application, Process Lasso just transfers already used resources to the program being launced so that it loads quicker. It does nothing to your CPU voltage settings or anything of the sort.

    Best cpu optimizer and manager! No more lag!

    Sounds awesome but don't like to risk and try it. Want to truly

    know that if somebody tested and tried it to work well or not ?!
