Recently, I want to test the overall performance of a machine. I searched google and found this tool, which can be used to test the memory pressure, memtester is mainly used to capture memory errors and bad bits that are always at a very high or low level. the main items in the test include random values, differences or comparisons, subtraction, multiplication, division, and or operations. you can test the existing memory of the system based on the size and number of tests. 1 download 1 wget http://pyropus.ca/software/memtester/old-versions/memtester-4.2.2.tar.gz 2 install 1tar zxvf memtester-4.2.2.tar.gz2cd memtester-4.2.2 www.2cto.com 3 make & make install 3 parameter introduction memtester [-p PHYSADDR] [ITERATIONS] the number of MEMORY for testing the MEMORY application. the default unit is megabytes (MB), or the number of times the B K M G ITERATIONS test is performed. the default value is unlimited 4, apply for a 10 m memory and test it once. for example, if you want to test the memory pressure for 5 trial, you can apply for a large memory, test nohup memtester 2G>/tmp/memtest in the background infinitely. log & author mastiff-split
