gzip

问题 We recently switched some of our sites from deflate to gzip and noticed a significant increase in cpu load on our servers. 回答1: Is it possible that you are experiencing cache miss? That is, compressed content is sometimes cached compressed but switching compression schemes would (or at least should) invalidate that cache causing dramatically increased cpu utilization. Did you try switching it back? 回答2: gzip is, basically, deflate with some additional headers. So there should not be a

问题 I'm trying to enable GZIP compression on IIS 7.5. I think all the settings are okay.

问题 I am trying to read a gunzipped file (.gz) in python and am having some trouble. I used the gzip module to read it but the file is encoded as a utf-8 text file so eventually it reads an invalid character and crashes. Does anyone know how to read gzip files encoded as utf-8 files? I know that there's a codecs module that can help but I can't understand how to use it. Thanks! import string import gzip import codecs f = gzip.open('file.gz','r') engines = {} line = f.readline() while line: parsed

问题 I have a large amount of data (~100k) that my C# app is sending to my Apache server with mod_gzip installed. I'm attempting to gzip the data first using System.IO.Compression.GZipStream. PHP receives the raw gzipped data, so Apache is not uncompressing it as I would expect. Am I missing something? System.Net.WebRequest req = WebRequest.Create(this.Url); req.Method = this.Method; // "post" req.Timeout = this.Timeout; req.ContentType = "application/x-www-form-urlencoded"; req.Headers.Add(
