Can I gzip JavaScript and CSS files in Django?

由 亡梦爱人 提交于 2019-12-04 10:23:31
I tried profiling my web application and one of the bottlenecks reported was the lack of gzip compression. I proceeded to install the gzip middleware in Django and got a bit of a boost but a new report shows that it is only gzipping the HTML files i.e. any content processed by Django. Is there a way I could kludge/hack/force/make the middleware gzip my CSS and my JS as well? Could someone please answer my questions below. I've gotten a little lost with this. I might have gotten it wrong but people do gzip the CSS and the JS, don't they? Does Django not compress JS and CSS for some browser

Tomcat with compression enabled causes error on OS X High Sierra

问题 We have been using Tomcat (v7) on OS X for quite some time now and never experienced any problems. However, after updating the OS to High Sierra, the web applications do not work anymore when compression is enabled in the server.xml. Chrome constantly shows an ERR_CONTENT_DECODING_FAILED (obviously without any content displaying). When compression is switched off, everything works fine. I assume the root of the problem is Apple's upgrade of zlib in High Sierra. Everything was working fine on

Noise reduction and compression in streaming audio

由 荒凉一梦 提交于 2019-12-04 09:47:39
hope you can help. I am recording audio from a microphone and streaming it live across a network. The quality of the samples is 11025hz, 8 bit, mono. Although there is a small delay (1 second), it works great. What I need help with is I am trying to now implement noise reduction and compression, to make the audio quieter and use less bandwidth. The audio samples are stored in a C# array of bytes[], which I am sending/receiving using Socket. Could anyone suggest how, in C#, to implement compression and noise reduction? I do not mind using a third party library as long as it is free (LGPL

I am looking for a compression component that supports Delphi2010 and allow me to do the basic operations of: create .zip archives extract from .zip archives delete .zip archives I also need the component to be free for commercial usage and possibly does not use/rely on a DLL (I don't mind if it does). So far I have looked into ZipForge , FlexCompress , KaZip and UnRAR , but I found out that I needed to purchase a license to commercially use ZipForge and FlexCompress. When it came to KaZip, there were errors in the code so I was unsuccessful in terms of installing the component. Whereas UnRAR

问题 My TCP Client receives a image within a packet.The image is compressed with zlib.The task is to decompress the image and put it on the form.

The code below loads the compressed file and saves it after decompression. private void decompressFile(string inFile, string outFile) {

Suggested Compression Ratio with H.264?

由 我只是一个虾纸丫 提交于 2019-12-04 07:27:33
问题 Note bene: I realize this is an immensely complicated question with about a million levels of nuance that I'm trying to reduce to a single number... I'm about to undertake a large video encoding project using H.264 encoding. We are trying to create multiple bitrate profiles in order to accommodate streaming across internet connections, processors, devices, etc. Generally speaking, what kind of compression ratio should I be expecting to see (while staying within a reasonable level of quality)?
