View CPU details

#If the CPU has several cores, it will output several repeated messages

Check CPU frequency

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

First, on the server side, enable the iperf service

iperf3 -s

Server 192.168.0.103

2) On the client, open the client and test the speed

iperf3 -c 192.168.0. 103

Memtester Introduction

Memtester is mainly used to capture memory errors and bad bits that are always very high or very low. The main test items include random values, XOR comparison, subtraction, multiplication, division, AND/OR operations, etc. By giving the size and number of test memory, the above items can be tested on the system's existing memory.

1. Download memtester-4.3.0.tar.gz from http://pyropus.ca/software/memtester/ ;

2. Execute the following command to install Memtester.

tar zxvf memtester-4.2.2.tar.gz

cd memtester-4.2.2

make && make install

3. Parameter Introduction

memtester [-p PHYSADDR] <MEMORY> [ITERATIONS]

Parameter Description:

MEMORY The amount of memory requested for testing, the default unit is megabytes, can also be BKMG.
ITERATIONS The number of tests, the default is unlimited.

Test Examples

Start the test, apply for 8M memory, and test once. As shown below:

You can use the free -h command to view memory usage.
