Remove packages to free space

Hi guys im new here, its my first time using openwrt and i want to know what can i remove/disable to gain some performance. I installed the firmware just to use sqm, im a normal internet user and i want only the basics i dont use ipv6, upnp, ddns and this type of things. Can you guys tell me what would i like to remove and how to?
This is it, thanks :grinning:

Hi ...
there is no way anymore to remove IPv6
since we don't know what is your device, and what is your use case, DumbAP, ordinary router, VPN router, etc ... nobody could suggest more specific solution
