负载测试中的延迟时间 [英] Latency Time in Load Testing

问题描述

我正在使用pylot 1.26工具进行负载测试，但这仅给了我平均水平.响应时间 平均吞吐量.从这些参数如何计算延迟时间?

I m Using pylot 1.26 tool for load testing but it just gives me Avg. Response Time & Avg. Throughput . from these parameter how can I calculate latency time??

或者建议我免费 * 工具 * 进行负载测试，这将为我提供这些参数. /p>

OR suggest me some FREE *TOOL* for load testing which will gives me these parameters.

推荐答案

我们的负载测试器产品捕获到第一个字节的时间 (TTFB).这是从请求开始到收到响应的第一个字节的时间.在网络服务器可以立即响应的少量请求(即GET)(即基于静态文件的资源)上，这很好地表明了往返时间.与延迟时间不完全相同，但接近.

Our Load Tester product captures time to first byte (TTFB). This is the time from the beginning of the request until the first byte of the response is received. On small requests (i.e. GETs) that the webserver can respond to instantly (i.e. static file-based resources), this is a good indication of round-trip time. Not exactly the same as latency, but close.

我不知道有任何专门用来测量延迟的负载测试工具.大多数只是给出响应时间，而更好的工具也可以测量TTFB.

I'm not aware of any load testing tools that measure latency specifically. Most just give response time and the better tools also measure TTFB.
