Hi!
There seems to be a speed issue from my ISP (AS34594) to Cloudflare.
speed.cloudflare.com gives me the following results (same with speedtest.net and WARP enabled):
While speedtest.net gives me the the full 50/50 bandwidth I have available (I chose a server in another AS which is also peering at CIX):
As the route to the speetest.ht.hr server is using the same route to the CIX, I conclude that the problem is not within my own ISP, since the traffic to AS5391 goes through the same CIX POP without any problems. (traceroute below.)
The slow download speed is constantly at around 20-30 Mbit/s. (Mostly ~22.)
This is problematic because it makes WARP+ (and all other CF traffic) much slower than using the internet directly.
Can someone at the Cloudflare network team have a look at this?
The traceroute from me to Cloudflare looks like this:

Traceroute from me to the speediest.ht.hr server - which connection is perfectly fine:
