壓力測(cè)試
ab -r -c 1000 -n 10000 http://example.com/
-r: 發(fā)生錯(cuò)誤也不中斷
-c: 併發(fā)request數(shù)量
-n: 總request數(shù)量
如果出現(xiàn)too many request錯(cuò)誤, 查看
ulimit -a
server就算能負(fù)荷台汇，你的local machine還不一定能接收如此多的request，把接收request數(shù)量條大一點(diǎn)
ulimit -n 10000
查看cache hit/miss
curl -I http://example.com
