Best practice
When comparing two processes or actions, use "significantly slower" to emphasize that the difference in speed is not just marginal, but statistically or practically important. For example: "The new algorithm performed the task significantly slower than the previous version."
Common error
Avoid assuming that because one process is "significantly slower" after an event, the event directly caused the slowdown. Investigate potential confounding factors before drawing causal conclusions. For example, a website loading "significantly slower" might be due to increased traffic, not just the recent code update.
