Reminds me of when a customer complained a DB-heavy processing step took about 10x as long as expected, ie 10 minutes instead of 1. We used on-prem DB server and fat clients. After a long debugging session I hadn't found anything. Gradping at straws I asked what kind of network they ran. Turned out the clients all ran on laptops connected through Wi-Fi... so yeah 10x latency turned into 10x longer job.
