High CPU utilization just after display sleep in Hackintosh

I noticed that after a few seconds the monitors went sleep, the CPU utilization and iGPU utilization of my hackintosh went significantly high. This was clearly noticed in the Intel Power Gadget as well,

I kept a terminal session open redirecting the output of top command in terminal (top -o cpu > bla.txt). From the output I was able to find out that mediaanalysisd process was utilizing the CPU and iGPU.

After unloading mediaanalysisd, the issue went away.

Uload command I used,
launchctl unload -w /System/Library/LaunchAgents/com.apple.mediaanalysisd.plist
