Has anyone experienced download issues using Cloudflare DNS in OpenWRT
I don't experience any problems while browsing normal websites; I only experience extreme speed limitations during downloads with Cloudflare. (Türk Telekom ISP TURKEY)
Are you DLing stuff from Cloudflare ?
When using Cloudflare DNS, I'm experiencing extreme speed throttling when downloading files. This problem doesn't occur with other DNS servers.
Then you should probably complain with Cloudflare ?
Which is pretty much the same outcome as last time you posted this question, in I'm experiencing download speed issues.

I'm wondering if anyone else is experiencing the same problem as me.
The Turk Telecom + Cloudflare + Openwrt combo probably isn't very common.
The DNS shouldn't slow speed once the lookup has completed, unless you're downloading from Cloudflare itself.
Can you provide your /etc/config/network file for review?
CF could in theory point OP to a CDN on the other side of the world, making DLing slow, but lookups fast.
This was also mentioned in the old thread.

Do a nslookup to CF for whatever site you use for the slow DLs.
Repeat using your ISPs DNS.
Are the IPs returned the same ?
If not, do a geoip lookup on both, compare location.

I agree with @frollic that it looks like a geoip issue.
Check which CF server you're talking to, see Cloudflare DNS not connecting to my city server - #2 by AndrewZ

Probably some censor diverts some DNS records to fast pipe

To test:
nslookup domain.example.com 1.1.1.1
nslookup domain.example.com <ISP_DNS>
The Cloudflare results should match you ISP's - if not, that's the issue.

... and it would be a CF issue, not OpenWRT.
