Performance Report

Perform a load test with 50 users for 1 minute and show me the response time of www.example.com.

The following report was created with PerformoBot and the query above.

Response time

	Min.	Max.	Mean.	Med.
Time:	after 55 s 124 ms	after 52 s 723 ms	-	-
Value:	558 ms	1334 ms	624.52 ms	592 ms

Info:
Response time is the total amount of time it takes to respond to a request for service. That service can be anything from a memory fetch, to a disk IO, to a complex database query, or loading a full web page. The response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time. The wait time is how long the request had to wait in a queue before being serviced and it varies from zero, to a large multiple of the service time.

Summary:
The overall minimum was 558 ms (after 55 s 124 ms) and the overall maximum was 1334 ms (after 52 s 723 ms). The maximum of 1334 ms and the minimum of 558 ms were recorded exactly once each.

Analysis Summary

Analysis Tool:	JMeter
Duration:	58 s 724 ms
Collected samples:	50
Metrics:	elapsed time, request status, server status, received traffic, latency, connection time, response time

Experiment summary:
From 10.09.2019 15:32:51 to 10.09.2019 15:33:50 50 values were recorded. JMeter was used as the load testing tool. During the execution of this experiment (58 s 724 ms) 50 virtual users produced load to the tested domain (www.example.com).

Tool description:
Apache JMeter is an Apache project that can be used as a load testing tool for analyzing and measuring the performance of a variety of services, with a focus on web applications. JMeter can be used as a unit-test tool for JDBC database connections, FTP, LDAP, Webservices, JMS, HTTP, generic TCP connections and OS native processes. One can also configure JMeter as a monitor, although this is typically... continue reading^[1].

Other metrics

Elapsed time

	Min.	Max.	Mean.	Med.
Time:	after 55 s 124 ms	after 52 s 723 ms	-	-
Value:	224 ms	607 ms	254.56 ms	238 ms

Info:
The elapsed time is the amount of time it takes to send the first request until the last response is received. This metric does not include the time a client is executing code.

Summary:
The overall minimum was 224 ms (after 55 s 124 ms) and the overall maximum was 607 ms (after 52 s 723 ms). The maximum of 607 ms and the minimum of 224 ms were recorded exactly once each.

Request status

Server status

Received traffic

	Min.	Max.	Mean.	Med.
Time:	at the beginning	after 4 s 723 ms	-	-
Value:	1592 bytes per request	1614 bytes per request	1600.64 bytes per request	1592 bytes per request

Info:
To perform a request, it is necessary to exchange data between client and server. This data consists of header data and meta information, which is needed by the server. The amount of exchanged information is measured in bytes.

Summary:
The overall minimum was 1592 bytes per request (at the beginning) and the overall maximum was 1614 bytes per request (after 4 s 723 ms). The maximum of 1614 bytes per request was recorded 9 times while the minimum of 1592 bytes per request was recorded 25 times.

Latency

	Min.	Max.	Mean.	Med.
Time:	after 55 s 124 ms	after 52 s 723 ms	-	-
Value:	224 ms	606 ms	253.68 ms	237 ms

Info:
Latency is the amount of time a message takes to traverse a system. In a computer network, it is an expression of how much time it takes for a packet of data to get from one designated point to another. It is measured as the time required for a request to be sent to the server and returned to its sender. Latency depends on the speed of the transmission medium and the delays in the transmission by devices along the way. A low latency indicates a high network efficiency.

Summary:
The overall minimum was 224 ms (after 55 s 124 ms) and the overall maximum was 606 ms (after 52 s 723 ms). The maximum of 606 ms and the minimum of 224 ms were recorded exactly once each.

Connection time

	Min.	Max.	Mean.	Med.
Time:	after 50 s 324 ms	after 34 s 723 ms	-	-
Value:	108 ms	139 ms	116.28 ms	115 ms

Info:
The connection time is the amount of time it takes to establish a connection between a client and the server. If the connection request between client and server was successful, the client can send further requests. If the connection was not successful, no further requests can be send to the server. The connection time is also part of the latency.

Summary:
The overall minimum was 108 ms (after 50 s 324 ms) and the overall maximum was 139 ms (after 34 s 723 ms). The maximum of 139 ms and the minimum of 108 ms were recorded exactly once each.
