【性能】并发调用http接口

连续并发调用http接口

#!/bin/bash
rm -rf time.txt diftime.txt shanpao_time.txt
for((i=0;i<2;i++))    #循环2次
do
{
for((j=0;j<3;j++))    #每次并发3个
do
{
begintime=`date +%s`    #当前时间
echo $i$j `date +'%Y%m%d %H:%M:%S' -d @$begintime` 'begin' >> time.txt
curl -d "longitude=117.961&latitude=24.6039&minRange=500&maxRange=300000&maxDistance=5000&cityName=厦门市" http://192.168.34.133:8090/queryRoadBookIdByRange.do
endtime=`date +%s`
echo $i$j `date +'%Y%m%d %H:%M:%S' -d @$endtime` 'end' >> time.txt
diftime=$(($endtime - $begintime))
echo $i$j $diftime >> diftime.txt
}&
done
}
done

求响应时间最大值、最小值、平均值

#!/bin/bash
# 平均值
cat diftime.txt|awk '{sum+=$2} END {print "Average=", sum/NR}' >> shanpao_time.txt
# 最大值
awk 'BEGIN {max = 0} {if ($2+0 > max+0) max=$2} END {print "Max=", max}' diftime.txt >> shanpao_time.txt
# 最小值
awk 'BEGIN {min = 65536} {if ($2+0 < min+0) min=$2} END {print "Min=", min}' diftime.txt >> shanpao_time.txt
