title: Does high cpu usage affect JAVA GC?
body: <p>Recently I am developing an android app for video conferencing. I observed that when the cpu usage is less than 95%, there is half free memory left. However when the cpu usage goes up, the memory usage will soon reach 90% and even more. I don`t have much knowledge with JVM or GC and I was wondering is the GC performance somehow related two the cpu usage? </p>
  
  <p>If it is, is there a advice that I can follow to balance cpu and memory usage?</p>
  
  <p>Thank you in advance.</p>
