非常感谢您的译文，此译文对我的帮助很大，最近也在认真比照学习此篇论文。
对于一个统计学里面的翻译不准确点，当然无关紧要，不知道准确不，可以找专业人看看。
The median latency
for trace data collection – that is, the time it takes data to
propagate from instrumented application binaries to the
central repository – is less than 15 seconds
跟踪数据收集（即从应用中的二进制数据传输到中央仓库所花费的时间）的延迟中位数少于15秒。
The 98th percentile
latency is itself bimodal over time; approximately
75% of the time, 98th percentile collection latency is less
than two minutes, but the other approximately 25% of the
time it can grow to be many hours
第98百分位的延迟往往随着时间的推移呈现双峰型;大约75%的时间，第98百分位的延迟时间小于2分钟，但是另外大约25%的时间，它可以增涨到几个小时。
