HTTP性能测试

web性能测试的方法请参考此连接说明：http://www.xenoclast.org/doc/benchmark/

1. httperf

ftp://ftp.hpl.hp.com/pub/httperf/ 下载
解压然后安装，执行程序在安装目录下的src目录中

./httperf –server 192.168.210.155 –port 10002 –uri /index.html –rate 300 –num-conn 30000 –num-call 1 –timeout 5*

??num?calls=_It specifies the total number of calls to issue on each connection before closing it
??num?connsthe total number of connections to create

httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE

Maximum connect burst length: 51

Total: connections 30000 requests 30000 replies 30000 test-duration 100.004 s

Connection rate: 300.0 conn/s (3.3 ms/conn, <=52 concurrent connections)
Connection time [ms]: min 0.5 avg 3.5 max 113.7 median 3.5 stddev 4.6
Connection time [ms]: connect 1.2
Connection length [replies/conn]: 1.000

Request rate: 300.0 req/s (3.3 ms/req)
Request size [B]: 78.0

Reply rate [replies/s]: min 290.2 avg 300.0 max 309.8 stddev 3.3 (19 samples)
Reply time [ms]: response 2.3 transfer 0.1
Reply size [B]: header 238.0 content 612.0 footer 0.0 (total 850.0)
Reply status: 1xx=0 2xx=30000 3xx=0 4xx=0 5xx=0

CPU time [s]: user 52.07 system 47.29 (user 52.1% system 47.3% total 99.4%)
Net I/O: 271.9 KB/s (2.2*10^6 bps)

Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0
Errors: fd-unavail 0 addrunavail 0 ftab-full 0 other 0

total: 表示总体情况
Connection：tcp 连接的相关统计信息，Connection length可能>1（由于persistent-connections）
Request rate：HTTP报文的发送统计信息
Reply rate： time表示发送第一个包到接收第一个包的时间， transfer表示读取接收报文的时间

2.autobench

对httperf进行了封装，不仅仅只测试一个条件的结果，可以连续增加测试量，从而测试出性能的瓶颈
下载地址： http://www.xenoclast.org/autobench/

默认的配置文件如下所示：
more autobench.conf

注意: 一定要将配置文件copy到所用用户的家目录下，因此程序执行需要读取这个文件；安装后默认在/usr/local/etc/autobench.conf

# Autobench Configuration File
# host1, host2 
# The hostnames of the servers under test
# Eg. host1 = iis.test.com 
#     host2 = apache.test.com
host1 = testhost1 
host2 = testhost2
# uri1, uri2
# The URI to test (relative to the document root).  For a fair comparison
# the files should be identical (although the paths to them may differ on the 
# different hosts)
uri1  = /
uri2  = /
# port1, port2
# The port number on which the servers are listening
port1 = 80
port2 = 80
# low_rate, high_rate, rate_step
# The ‘rate‘ is the number of number of connections to open per second.
# A series of tests will be conducted, starting at low rate,
# increasing by rate step, and finishing at high_rate.
# The default settings test at rates of 20,30,40,50...180,190,200
low_rate  = 20
high_rate = 200
rate_step = 10
# num_conn, num_call
# num_conn is the total number of connections to make during a test
# num_call is the number of requests per connection
# The product of num_call and rate is the the approximate number of
# requests per second that will be attempted.
num_conn  = 5000
num_call  = 10
# timeout sets the maximimum time (in seconds) that httperf will wait
# for replies from the web server.  If the timeout is exceeded, the
# reply concerned is counted as an error.
timeout   = 5
# output_fmt
# sets the output type - may be either "csv", or "tsv";
output_fmt = tsv
## Config for distributed autobench (autobench_admin)
# clients  
# comma separated list of the hostnames and portnumbers for the
# autobench clients.  No whitespace can appear before or after the commas.
# clients = bench1.foo.com:4600,bench2.foo.com:4600,bench3.foo.com:4600
clients = localhost:4600

执行测试命令
./autobench –single_host –host1 192.168.210.155 –port1 10002 –uri1 /index.html –quiet –low_rate 20 –high_rate 200 –rate_step 20 –num_call 10 –num_conn 5000 –timeout 5 –file results.tsv
