TweakMASTER requires some system resources when open. Any computer bought in the last 5-7 years should be able to run TweakMASTER without any problem.
TweakMASTER Agent is designed to be run in the background in order to support some TweakMASTER functions (DNS Acceleration, Clock Synchronization, and some others). This small executable is designed to require as little system resources (memory, CPU, etc.) as possible. CPU time is negligible and private working set (memory usage) drops to under 1 MB after it runs for a few minutes.
