Hi there, we are using fly.io for 2+ years and really love it.
What we were debugging today yet did not make any sense though!
on one machine issuing a SQL query against a remote PostgreSQL running on Hetzner connected via fly wireguard VPN was very slow (17 seconds instead of expected 1 second)
we then scaled to 2nd machine (same region =cdg). same query on 2nd machine was fast (1 second)
did this on both machines:
- we checked network performance with iperf → same results on both machines
- we checked cpu and ram speed with sysbench → same results on both machines
both machines are still up in case you want to have a look!
appreciate any help or explanations
Steve
