Node+Express test server performance

1 Test Environment

1.1 Server Hardware

The host to be tested is AWS cloud server. Two tests are selected

1.1.1 t2.micro

t2.micro is an EC2 with breakthrough performance, which is the server in AWS global free package. The configuration is as follows:

t2.micro is an EC2 with breakthrough performance, which is the server in AWS global free package. The configuration is as follows:

Single core 1G, CPU performance is 0.45ECU, and can reach 2ECU when performance is improved. The network performance is said to be 20Mbps~100Mbps

PS: EC2 Compute Unit (ECU) – One EC2 Compute Unit (ECU) is equivalent to the computing power of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon CPU.

1.1.2 c5.large

Then we selected a c5.large for evaluation.

Dual-core 4G, performance can reach 9ECU

1.1.3 Press

The press machine is another c5.large in the same availability zone.

1.2 Testing Tools

1.2.1 Test terminal

The ab tool is mainly used for testing. The ab tool can run up to 200 million concurrently, which is sufficient for single-machine testing.

For the use of ab tools, please refer to another blog: https://www.jb51.net/article/231502.htm

1.2.2 Server Monitoring

The server-side monitoring mainly uses the AWS backend cloudwatch service, and the CPU and memory usage are checked in the top tool.

For the use of top command, please refer to another blog:

1.3 Test Method

Add a test route directly in the express framework app.js and return res.end() directly.

2 Test Data

2.1 c5.large

We can see from the figure that when the concurrency is 2000, the average response time is 874.725ms, and the QPS is around 2286.43. On a 2-core 4G server with more than 300/month, the performance of the express framework itself is not bad.

2.2 t2.micro

We can see from the figure that when the concurrency is 300, the average response time is 189.191ms, the QPS is around 1585.7, and the performance of T2 at 70 blocks/month is quite good. However, it can also be seen from the figure that after the concurrency reaches 1000, the overall performance is not very stable.
