Android Studio 3.1 gets more CPU and memory usage

Question

I just updated Android Studio 3.0.1to3.1

Build #AI-173.4670197, built on March 22, 2018
JRE: 1.8.0_152-release-1024-b02 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 8.1 6.3

I noticed that it uses more processor and memory. In this regard, in response, he became slow. It annoys me. Please give some suggestion to get rid of it.
