服务器带宽不够的情况下，可以使用apache启用mod_deflate的GZIP压缩网页传输。gzip原本是文件压缩格式，扩展名为.gz，HTTP协议用它来改进WEB应用程序性能，加快HTTP请求返回内容的下载速度，降低网络带宽占用。 LoadModule deflate_module modules/mod_deflate.so LoadModule headers_module modules/mod_headers.so <IfModule mod_deflate.c> DeflateCompressionLevel 3 # 压缩程度的等级 AddOutputFilterByType DEFLATE text/htmltext/plaintext/csstext/xmltext/javascript#特定的MIME类型指定输出过滤器 AddOutputFilter DEFLATE css js#压缩后输出 SetOutputFilter DEFLATE # 插入过滤器，对所有输出启用压缩 # 不压缩图片等格式文件 SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzipdont-vary SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no

Similar to my last question, I'd like to have a PHP function that can take a local path and tell me (a) how much the total file size is for HTML, CSS, JS and images, and (b) the total load time for this page. Like YSlow I think, but as a PHP function. Any thoughts? I looked around and was wondering can I use CURL for this? Even though I need to check paths that are on my own server? thanks! Update: After reading the comments, realizing I'm off base. Instead wondering is there a way programatically get a YSlow score for a page (or similar performance score). I assume it would need to hit a

I'm using https://code.google.com/p/python-ntlm/ for authenticating and then using a system call to get the response from YSlow. I am not quite sure on how to 'convert' the needed info to a variable that will provide me the response I desire. I tried other solutions...but here I am... user = 'domain\userName' password = "password" url = "http://someUrlHere.com" # User must be granted access in order for script to work... passman = urllib2.HTTPPasswordMgrWithDefaultRealm() passman.add_password(None, url, user, password) # create the NTLM authentication handler auth_NTLM = HTTPNtlmAuthHandler

As I'm starting to do some front end engineering at work, I would like to properly quantify the speedup achieved. I would like to be able to use an average value of, say, 50 page load times measured by YSlow or Google Page Speed. Obviously, I don't want to hit reload 50 times and write down the value. Is there a FF plugin for that or will I have to write a Firebug extension myself? Or maybe there is a non-FF, command-line tool that does what I'm planning? AutomatedTester I recently did a talk about this at Google Test Automation Conference in Zurich for this. Slides for it are here And I did a
