Pi-hole memory usage very high

Expected Behaviour:

i have allocated. 1 G of ram to LXC container that is running pi hole and i can see the stats of the container from proxmox that it is not consuming much Ram and the stats from within the container as well, so within pi-hole we should see low memory usage.
-operating system
-LXC _

Actual Behaviour:

pi hole Gui shows around 93 to 94% memory usage even after reboot.
