I’ve been dealing with this issue for over 10 days, so I can guarantee it’s not a problem with the source code. Query responses are instantaneous for days on end, but at times, they experience very high latency. Dashboards that used to take 2 seconds now take 7 seconds—and then, without me doing a thing or making any changes, they go back to normal. Is anyone else experiencing this problem?

Here are the first things I'd check:
Measure where the time is spent.
Is the delay during the initial connection?
During authentication?
While running queries?
Only on the first query after connecting?
Check network latency.
If your application isn't running in the same region as the Railway database, network round trips can add significant delay.
Look at slow queries. Run:
EXPLAIN ANALYATED SELECT ...;
for any slow query to see if indexes are being used.
Connection pooling. Opening a new MySQL connection for every request can make the application feel slow. Reusing connections through a pool is much faster.
Server load. Check Railway metrics (CPU, memory, disk I/O, connection count). If the database is under heavy load, response times will increase.
After the MySQL upgrade. Since you also mentioned authentication issues after upgrading, it's possible the upgrade changed configuration, DNS behavior, or authentication plugins. Review the MySQL error log and Railway deployment logs for warnings.
To narrow it down, could you answer these questions?
Approximately how long is the delay (500 ms, 2 seconds, 10+ seconds)?
Is the slowness in connecting, executing queries, or both?
What language/framework are you using (Node.js, Python, PHP, Go, etc.)?
Are you connecting from Railway, another cloud provider, or your local machine?
Does every query feel slow, or only certain ones?

I’ve been dealing with this issue with my MySQL database on Railway for over a month now. I’m planning to migrate away; this situation is simply unacceptable. For no apparent reason, queries start slowing down and lagging for days, then return to normal for a while—it’s a constant back-and-forth. It’s been very slow since yesterday—including right now—making it impossible to keep going.
