如何加快HTML页面加载速度

初次接触LTP (Linux Test Project) 被LTP的各种man文件、LTP官网文档还有网上找的七七八八的文章搞得一头雾水,怎么都测试不成功,不知道是我英文太烂没理解对还是它写的不清楚。经过反复摸索终于成功了,现详述如下,还望各位看客不要嫌我写得罗嗦,希望对初次安装使用LTP测试套的人有所帮助。

一、下载LTP测试套

可以从http://sourceforge.net/projects/ltp/files/LTP Source/下载最新的LTP压缩包,如ltp-full-20110228.bz2

下载后建议存放到/home目录下,不要放在/root目录下,因为一些测试需要非root用户来完成。

解压、编译、安装:

1、tar jvxf ltp-full-20110228.bz2

2、cd ltp-full-20110228.bz2

3、./configure (此步可能不成功,则先执行make autotools,然后再./configure)

4、make

5、make install

注意:ltp 的默认安装路径是/opt/ltp,所以接下来的执行测试步骤都需要在/opt/ltp目录下完成(这个一定要特别注意,我当时就误到这了,在/home目录下折腾半天总是测试报错

FATAL: LTP not installed correctly

INFO: Follow directions in INSTALL!

原来不是安装错误,是进错文件夹了)

二、执行测试

当前有三个脚本可用于执行LTP测试套件,分别是runltp、networktests.sh以及diskio.sh。最常用的就是runltp脚本,它可用于执行LTP中绝大部分的测试(default set of tests,但是不包括networktests及diskio测试。

执行./runltp的一些选项参数如下(借用官网):

-a EMAIL_TO EMAIL all your Reports to this E-mail Address

-c NUM_PROCS Run LTP under additional background CPU load

[NUM_PROCS = no. of processes creating the CPU Load by spinning over sqrt()

(Defaults to 1 when value)]

-C FAILCMDFILE Command file with all failed test cases.

-d TMPDIR Directory where temporary files will be created.

-D NUM_PROCS,NUM_FILES,NUM_BYTES,CLEAN_FLAG

Run LTP under additional background Load on Secondary Storage (Seperate by comma)

[NUM_PROCS = no. of processes creating Storage Load by spinning over write()]

[NUM_FILES = Write() to these many files (Defaults to 1 when value 0 or undefined)]

[NUM_BYTES = write these many bytes (defaults to 1GB, when value 0 or undefined)]

[CLEAN_FLAG = unlink file to which random data written, when value 1]

-e Prints the date of the current LTP release

-f CMDFILES Execute user defined list of testcases (separate with ',')

-g HTMLFILE Create an additional HTML output format

-h Help. Prints all available options.

-i NUM_PROCS Run LTP under additional background Load on IO Bus

[NUM_PROCS = no. of processes creating IO Bus Load by spinning over sync()]

-l LOGFILE Log results of test in a logfile.

-m NUM_PROCS,CHUNKS,BYTES,HANGUP_FLAG

Run LTP under additional background Load on Main memory (Seperate by comma)

[NUM_PROCS = no. of processes creating main Memory Load by spinning over malloc()]

[CHUNKS = malloc these many chunks (default is 1 when value 0 or undefined)]

[BYTES = malloc CHUNKS of BYTES bytes (default is 256MB when value 0 or undefined) ]

[HANGUP_FLAG = hang in a sleep loop after memory allocated, when value 1]

-N Run all the networking tests.

-n Run LTP with network traffic in background.

-o OUTPUTFILE Redirect test output to a file.

-p Human readable format logfiles.

-q Print less verbose output to screen.

-r LTPROOT Fully qualified path where testsuite is installed.

-s PATTERN Only run test cases which match PATTERN.

-t DURATION Execute the testsuite for given duration. Examples:

-t 60s = 60 seconds

-t 45m = 45 minutes

-t 24h = 24 hours

-t 2d = 2 days

-T REPETITION Execute the testsuite for REPETITION no. of times

-v Print more verbose output to screen.

-w CMDFILEADDR Uses wget to get the user's list of testcases.

-x INSTANCES Run multiple instances of this testsuite.

执行LTP测试的方式主要有两种,一种是执行全部default set of tests, 另一种是执行user defined set of tests。

1、执行default set of tests

cd /opt/ltp (你所安装的ltp的存放目录,默认是/opt/ltp)

./runltp -p -l result.log

2、执行user defined set of tests

如果你只是想执行LTP中的一部分test cases,你可以按照如下步骤操作:

cd /opt/ltp/runtest

vim your_command_file (创建命令文件,当然也可以使用runtest目录中现有的命令文件)

命令文件由两部分组成,一是test case标签“tag",另一个是你希望执行的具体的"test case"脚本名以及一些参数。比如:

#Tag Test case

#---------------------------------------

mtest01 mtest01 -p 10

cgroup_fj run_cgroup_test_fj.sh

controllers test_controllers.sh

cpuctl_stress run_cpuctl_stress_test.sh 9

编辑结束后保存你的命令文件,执行

cd .. (退出runtest目录,回到/opt/ltp目录)

./runltp -p -l result.02.log -f your_command_file

大功告成,此时测试如果还会报错,那就可能是你的命令文件中参数设置不正确,可根据error提示去检查命令文件及相应的脚本文件,一些脚本文件可能需要特定的参数才能正确执行。
