Question
Tizen Studio consumes 30% or more of CPU resources even when idle, without any background tasks running. Initial investigation suggests that the issue stems from the Tizen Common plugins, specifically a thread created by these plugins. Disabling the plugins resolves the CPU issue but breaks essential functionality like deploying to emulators.
Answer
Problem Understanding
Multiple users across different platforms (Windows 7/10, Mac, Ubuntu) report high CPU usage (20-100%) when running Tizen Studio, particularly with the Tizen Common plugins enabled. The issue appears to be related to the DeviceMonitor class in org.tizen.common.sdblib_2.0.0.201610251816.jar.
Solution Methods
- Official Fix: Update to Tizen Studio 1.1.1 or later, where this issue has been resolved.
- Temporary Workaround:
- Disable Tizen Common plugins (but this breaks deployment functionality)
- Use
sdbcommands directly for deployment
- Configuration Adjustment:
- Try increasing memory settings in
eclipse.ini(though many users report this doesn't help) - Location:
installation_path/tizen-studio/ide/eclipse.ini - Parameters to modify:
XmxandMaxPermSize
- Try increasing memory settings in
Additional Tips
- The issue was particularly problematic for laptop users due to heat and battery consumption
- The fix was officially released in version 1.1.1 (February 27, 2017)
- For package manager CPU usage during updates (which can reach 100%), this is normal behavior during downloads but should return to normal afterward
