Ubuntu-phpstorm java environment jdk is too resource-consuming

In the phpstorm java environment, jdk is too resource-consuming and a phpstorm is installed, which means less resource consumption than netbeans. as a result, it is found that java processes consume too much cpu, generally from 100% ~ 300%. how can I work when my computer is killed? I can't knock on the code. Could you please enlighten me ~~ My computer configuration is like... in the phpstorm java environment, jdk is too resource-consuming and a phpstorm is installed, which means less resource consumption than netbeans. as a result, it is found that java processes consume too much cpu, generally from 100% ~ 300%. how can I work when my computer is killed?

For windows users, phpstorm is not under pressure.

For windows users, the memory usage is about MB. The cpu is generally maintained at 0% without pressure.
