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−conns
the 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

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
httperf: warning: open file limit > FD_SETSIZE; limiting max. # of open files to FD_SETSIZE
如果不添加参数，则默认使用配置文件中的参数
最后的结果是tsv格式的文件，可以使用1.10版本后自带的工具，通过gnuplot画图得出图形结果
bench2graph takes a TSV format autobench results file, and uses gnuplot to graph the results, producing output in Postscript.
注意生成的图片格式是Postscript
./bench2graph results-1.tsv results-1.ps
windows下建议使用 GhostView来打开图片
