Welcome to guider wiki!
- What is guider?
Do you struggle to improve system performance or to find root cause that makes system abnormal?
Guider is made to measure amount of system resource usage and to trace system behavior.
You can analyze your performance issues effectively with this tool.
Guider pursues three characteristics as bellow.
1. easy to use: just run without installation or setting
2. measure correctly: time in ms, size in MB
3. integrate features: show as much information as possible
Document are available.
