What does P50, P90, P99 mean?

P50 (Median Latency): 50% of requests are faster than this value. This represents the typical user experience. P90 (90th Percentile Latency): 90% of requests are faster than this value. The slowest 10% of users experience worse performance. P99 (99th Percentile Latency): Only 1% of requests take longer than this value.

Is 90% a good confidence level?

The 95% confidence level is often used, though the 99% CI are used occasionally. At 99%, the width of the CI will be larger but it is more likely to contain the true population value, than the narrower 95% CI. Bioequivalence testing makes use of the 90% CI.
