Concurrency Performance test
1 Purpose of testing
According to the test results of Apache and Nginx concurrency performance, the advantages and disadvantages of concurrency model are analyzed.
Performance evaluation items include: RPS (number of processing requests per second), CPU utilization, memory usage, maximum concurrency.
According to the advantages and disadvantages of Apache and Nginx concurrency model, the appropriate concurrency model framework is chosen.
2 test environment
1. Hardware environment
Server: Interl Server Borad
8-Core cpu,2g memory, 160G HDD,
Client: Same as server-side environment
2. Operating system
Operating system: Red Hat EnterPrise kernel Linux 2.6.18
Client: Red Hat EnterPrise kernel Linux 2.6.9
3. Network topology
Server and client connect a switch via a gigabit network
Server IP Address: 192.168.192.201
Client IP Address: 192.168.192.200
3 Test methods
3.1 Test Tools
Apache 2.2.10 comes with tools bench
Webbench 1.5
3.2 Test Steps
1, equipment inspection and installation
Check that all system devices are intact and connect the device to the host.
2. Network connection Check
Servers and clients are connected to the same switch with a gigabit network cable
3, operating System preparation
Start Red Hat Enterprise
Install the mouse driver, configure the network
4. Download, install, configure
Reference Appendix
5. Apache Test
Run Apache
Cd/usr/local/apache/bin
./apachectl-k Start
Test Apache service successfully started
Access under Windows: http://192.168.192.201/index.html
Appears "It works! The test page
Run the Apche bench test program
Cd/usr/local/apache/bin
./ab-c Clients-n Requests http://192.168.192.201/index.html
Run the Webbench test program
Cd/usr/local/bin
Webbench-c clients-t Time http://192.168.192.200/index.html
(Clients represents the number of users, requests represents the number of concurrent)
6. Nginx Test
Run Nginx
./nginx
Test Nginx Service successfully started
Access under Windows: http://192.168.192.201/index.html
The "Welcome to nginx!" page appears
In order to test the results of the contrast, the Apache test page index.html Copy Overlay nignx test page
Run the Apche bench test program
Cd/usr/local/apache/bin
./ab-c Clients-n Requests http://192.168.192.201/index.html
Run the Webbech test program
Cd/usr/local/bin
Webbench-c clients-t Time http://192.168.192.200/index.html
7. Record Test results
Record bench test results: Time taken for tests (test times, units: seconds), requests per second (number of requests processed per second)
Record Webbench test results: speed (processing requests per minute, in order to be consistent with Apache bench, log *30 to process requests per second), run time according to Operation command-T specified, default 30 seconds
View CPU Usage command: Top
Memory usage Command: FREE
4 Test Plan
Nginx Single Thread test
Nginx multithreaded Test
Apache woker Mode Test
Apache prefork Mode Test
5 Summary of data
Test configuration: Apache configuration Reference 7.4,nginx Configuration Reference 7.5
Raw data See original data xls
The data are summarized as follows:
Server Client RPS

7.4 Apache Configuration
Apache configuration command:
Cd/usr/local/apache/conf
VI http.conf
Parameter configuration in Prefork mode:
Configure Apache
Prefork Mode--with-mpm=prefork
System startup creation process number Startservers 128//for Nginx comparable
Number of active sub-processes Serverlimit 50000
Number of processing connections in the child process lifetime Maxrequestsperchild 0//0 is unlimited
Maximum number of child processes maxclients 50000

Listening on port server {
Listen 80;
}
Sendfile Sendfile on;
I/O multiplexing method use Epoll;
Multi-worker process configuration:
Configure Nginx
Process Worker_processes 16;
