xmrig-proxy v3.2.1 takes up much more memory than the previous version
I have recently updated xmrig-proxy version from v2.13.0 to v3.2.1

It used around 100MB RAM with v2.13.0, but more than 3GB RAM with v3.2.1 now.

I have been using almost the same options for the proxy ( mining pool and algorithm as well)

I am just curious that it is normal that it requires more memory in version 3.
