正文

测试串行、并发、读、写 4类操作，每类操作又可以指定各种bs及count值，循环压测。每种场景一般执行3次，取平均值。

一、串行写

#!/bin/sh bs_list=(256k 1024k 10M 20M 50M 100M 1G)cnt_list=(40000 10000 1000 500 200 100 10) for i in {0..6}do for j in {0..2}do logfile=dd_${bs_list[$i]}_cnt${cnt_list[$i]}_${j}.txt echo -e "test ${j} started\n" > $logfileecho -e "started time `date`\n" >> $logfile dd if=/dev/zero of=testfile1 bs=${bs_list[$i]} count=${cnt_list[$i]} oflag=direct,nonblock 2>> $logfile echo -e "\nfinished time `date`" >> $logfileecho -e "\ntest ${j} finished" >> $logfilesleep 5 done sleep 30done
复制

二、 4并发写

#!/bin/sh # ddtest_write_conc.sh bs_list=(256k 1024k 10M 20M 50M 100M 1G)cnt_list=(40000 10000 1000 500 200 100 10) for i in {0..6}do for j in {0..2}do logfile=dd_conc_${bs_list[$i]}_cnt${cnt_list[$i]}_${j}.txt echo -e "test ${j} started\n" > $logfileecho -e "started time `date`\n" >> $logfile for conc in {0..3}do{dd if=/dev/zero of=testfile1 bs=${bs_list[$i]} count=${cnt_list[$i]} oflag=direct,nonblock 2>> $logfile} &done wait echo -e "\nfinished time `date`" >> $logfileecho -e "\ntest ${j} finished" >> $logfilesleep 5 done sleep 30done
复制

三、串行读

 #!/bin/sh # ddtest_read_serial.sh bs_list=(256k 1024k 10M 20M 50M 100M 1G)cnt_list=(40000 10000 1000 500 200 100 10) for i in {0..6}do for j in {0..2}do logfile=dd_${bs_list[$i]}_cnt${cnt_list[$i]}_${j}.txt echo -e "test ${j} started\n" > $logfileecho -e "started time `date`\n" >> $logfile dd if=testfile1 of=/dev/null bs=${bs_list[$i]} count=${cnt_list[$i]} iflag=direct,nonblock 2>> $logfile echo -e "\nfinished time `date`" >> $logfileecho -e "\ntest ${j} finished" >> $logfilesleep 5 done sleep 30done
复制

四、 4并发读

#!/bin/sh bs_list=(256k 1024k 10M 20M 50M 100M 1G)cnt_list=(40000 10000 1000 500 200 100 10) for i in {0..6}do for j in {0..2}do logfile=dd_conc_${bs_list[$i]}_cnt${cnt_list[$i]}_${j}.txt echo -e "test ${j} started\n" > $logfileecho -e "started time `date`\n" >> $logfile for conc in {0..3}do{dd if=testfile1 of=/dev/null bs=${bs_list[$i]} count=${cnt_list[$i]} iflag=direct,nonblock 2>> $logfile} &done wait echo -e "\nfinished time `date`" >> $logfileecho -e "\ntest ${j} finished" >> $logfilesleep 5 done sleep 30done
复制

五、输出解析

取执行时间

cat dd_* | grep -E 'MB/s|GB/s' | awk '{ print $6 }'
复制

取吞吐量

cat dd_* | grep -E 'MB/s|GB/s' | awk '{ print $8 }'
复制
