but I guess the other thing ill say with community pod i learnt is that: Networking is usually affected by the source / destination bandwidth, so usually pods are fast enough but the end area to download like HF / civitai can sometimes bottleneck u. (I actually wrote a script for speed testing to see if it ur pod fault or to try to isolate to ur end desination fault)
But another thing i learnt during that time from the staff was that community pods are sharing the same network bandwidth as potentially other pods in the same region. so sometimes what u can get is that another pod on the same community pod network is throttling the whole bandwidth. (This is rare but it happens), vs secure pods, the data center has enough money for expensive networking equipment so that every pod essentially has its own lane.
Im not a networking expert, by any means, just what i had learnt in a different networking question in the past
