The Solution

Max-IT (CPU) ensures that each running process will get its fair share of CPU resources, enabling it to run smoothly and co-exist alongside CPU-hungry and rogue applications. At the most basic level, Max-IT (CPU) achieves fair-sharing across all running processes as follows:

• A fixed share of CPU resources is reserved to NT Authority (the operating system). By default, this share is 20 percent.
• The “target percent CPU time” is then computed as (100 - Reserved) / (number of active processes), where Reserved is the percent CPU share reserved for NT Authority.
• The “average percent CPU time” is calculated for each active process.
• Processes whose “average percent CPU time” has fallen below the “target percent CPU time” will get their priority levels set to NORMAL.
• Processes whose “average percent CPU time” has risen above the “target percent CPU time” will get their priority levels set to BELOW NORMAL.
• Processes whose “average percent CPU time” has fallen to zero get their priority levels set to ABOVE NORMAL.
• The above process is then repeated every several hundred milliseconds. The default setting is 100 milliseconds.

Max-IT (CPU) also makes use of proprietary and sophisticated techniques above and beyond what is described above. These techniques further improve the application response times and enhance the end-user’s experience.
