NFS not starting on boot and slow speed

hey guys openwrt is working like a charm on my router but i added a ssd drive i had laying around to it
ext4 filesystem but over nfs read and write speeds are terrible ~4mb/s
hdparm shows it can do way higher speeds also top doesnt say the cpu is very active
any advice? or maybe logs i can post to pinpoint the problem

also after i reboot the router i have to /etc/init.d/nfsd restart for nfs to work at all

oh i forgot to add i have a xiaomi r3p pro
