CPU and Memory Usage raised after update Java #23
Comments
|
I tested with the Java 1.8.0_45 but could not find any problem. Recently, an user faced a similar problem (high CPU usage). He found that NetWorx raised 航海日誌's CPU usage. It is possible that some network related software changes the machine's network API behavior and the 航海日誌's proxy thread goes out of control, which raises CPU usage. Could you investigate more on your machine? Some software running on your computer might cause the high CPU usage. |

You can see the logbook use 75% CPU and 400M memory. 发件人: Nekopanda [mailto:notifications@github.com] I tested with the Java 1.8.0_45 but could not find any problem.

After I updated my Java Runtime to Version 8 Update 40 and above, the software's average CPU usage raised to 70%, sometimes 100%. The memory usage also raised to ~700M. I'm using Windows 8.1(x86_64), current Java version is Version 8 Update 45 (1.8.0_45, x86_64).
