The Mastodon instance that I use is very slow. Tell me how to find one with low latency.
To find a Mastodon instance with low latency, you can follow these steps:

1.  Check the instance's availability and response time with tools such as ping or traceroute.
2.  Look for instances with a low user count as larger instances tend to have more latency due to the strain on their servers.
3.  Read reviews or ask for recommendations from other Mastodon users.
4.  Test multiple instances to determine which one provides the best performance for you.

Keep in mind that the latency of an instance can also be affected by various other factors such as your location, internet connection speed, and the instance's hardware and network infrastructure.
How do you determine what exactly is causing the delay?
