As organizations continue to migrate to the cloud, it’s important to get in front of performance issues, such as high latency, low throughput, and replication lag with higher distances between your users and cloud infrastructure. ScaleGrid also maintains 53% lower latency on average throughout the entire MySQL AWS performance tests.

Faster detection of a bad connection is accomplished when there’s a lower value, while latency or intermittent network issues may be better served by increasing it slightly – although overly long timeouts can result in application hang-ups with little chance for an established link. Careful consideration must be given before making changes.
