We are planning to move from X86 environment environment to arm based environment and in the process we wanted to test Graviton instance - c7g
I am trying to implement gzip compression in Apache using the following steps.
SetOutputFilter DEFLATE
SetEnv force-gzip true
DeflateCompressionLevel 9
DeflateMemLevel 9
DeflateWindowSize 1
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
AddOutputFilterByType DEFLATE application/x-font-opentype
AddOutputFilterByType DEFLATE application/x-font-otf
AddOutputFilterByType DEFLATE application/x-font-truetype
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE font/opentype
AddOutputFilterByType DEFLATE font/otf
AddOutputFilterByType DEFLATE font/ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml
# Remove browser bugs (only needed for really old browsers)
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
Header append Vary User-Agent
Also made sure the modules mod_filter and mod_deflate is enabled. Per Amazon documentation, https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.migration-al.html
Does this means we can't use gzip compression even at Apache level
Kindly confirm
Gzip is not working properly. I have added the below code in .htaccess to enable gzip. but it doesnot make any change in Compressing my website:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddType x-font/otf .otf
AddType x-font/ttf .ttf
AddType x-font/eot .eot
AddType x-font/woff .woff
AddType image/x-icon .ico
AddType image/png .png
AddType text/css .css
In checkgzipcompression.com, it says Gzip is enabled. Any ideas in solving this issue?
I'm using deflate in a .htaccess-file. But this does not work in WampServer:
# deflate depending on filetype
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/atom_xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-shockwave-flash
</IfModule>
What am I doing wrong?
I'm trying to speed up my website. Google insights (https://developers.google.com/speed/pagespeed/insights) tells me that a critical problem is to enable GZip compression.
The address of the site is http://user2.net
It's based on codeigniter framework.
I have enabled gzip compression with folowing changes to my .htaccess file:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
<files *.html>
SetOutputFilter DEFLATE
</files>
I have tested the site with this tool:
http://www.gidnetwork.com/tools/gzip-test.php
It says that gzip is enabled.
What am I missing?
Did you try these lines in your .htaccess?
<IfModule mod_deflate.c>
<FilesMatch "\.(html|php|txt|xml|js|css)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
It works for my site.
First, check if gzip is enable in your server. You can use this tool:
http://checkgzipcompression.com/
If it's ok, then, check that the compression is working FOR ALL your files.
If Google Page Speed Test found on single file without GZIP compression from your server, the website with fail the test.
You can use Google Chrome for this:
Inspect your code; in the image you can see there is Content Encoding GZIP for the html file.
Clic on every file and find which doesn't have the GZIP encode; maybe the CSS type o JS type.
When you find it, add the file type to your gzip.conf
This is the simple configuration for gzip.conf
gzip on;
gzip_disable "MSIE [1-6]\\.(?!.*SV1)";
gzip_proxied any;
gzip_types text/plain text/css text/javascript text/xml application/javascript application/x-javascript application/xml application/xml+rss image/x-icon image/svg+xml image/jpeg image/jpg image/png
gzip_vary on;
Good Luck!
There are three ways to enable gzip compression -
By configuring server settings
For apache -
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
For nginx
gzip on;
gzip_comp_level 2;
gzip_http_version 1.0;
gzip_proxied any;
gzip_min_length 1100;
gzip_buffers 16 8k;
gzip_types text/plain text/html text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;
gzip_disable "MSIE [1-6].(?!.*SV1)";
gzip_vary on;
And by editing .htaccess as shown above
<IfModule mod_deflate.c>
<FilesMatch "\.(html|php|txt|xml|js|css)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
Source: Enable compression
It's the redirect, it sets 2 headers
first 301 (or 302, didn't check)
second 200 + gzip
For anyone who may be having an "Uncompressed Pages" issue after running a SEMRush site audit, try adding the following to your .htaccess
<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html|txt|css|js|php)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_Gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>
Always remember to backup your .htaccess file before making any edits, as a simple typing error could cause certain features of your website to fail or even worse - break your entire website.
Reference: https://www.semrush.com/blog/improve-page-load-times-htaccess-file/
Google has addressed this exact same concern in their FAQ as why would you get the errors to compress/gzip your files.
Checkout from Google's Insights:
https://developers.google.com/speed/docs/insights/EnableCompression#FAQ
Earlier they used to have a chome extension but now it has been removed so they point you to https://developers.google.com/speed/pagespeed/insights/ where when you enter any url, they tell which particular files or scripts are still eligible for compression or blocking the page render or both.
Hope this helps.
i have a linode sever with centos 6 , as it wont support mod_gzip, i am using mod_deflate.
this is my code in .htacess
<IfModule mod_deflate.c>
<FilesMatch "\\.(js|css|html|htm|php|xml)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
when i tested using http://www.whatsmyip.org/http-compression-test/ , its saying 'my site is gzipped' , but when i used pagespeed in chrome, it still suggest 'Enable compression'
whats wrong? any problem with my .htaccess code?
I used deflate mode in this way:
<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
AddOutputFilterByType DEFLATE application/x-font-opentype
AddOutputFilterByType DEFLATE application/x-font-otf
AddOutputFilterByType DEFLATE application/x-font-truetype
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE font/opentype
AddOutputFilterByType DEFLATE font/otf
AddOutputFilterByType DEFLATE font/ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml
</IfModule>
And it's working perfectly for me. Pagespeed for my site is:
Desktop: 91
Mobile: 83

I've had this same problem. It seems pagespeed in Chrome sometimes gives the wrong results. I recommend using http://webpagetest.org or http://gtmetrix.com if you really want to be sure. You should always test these sorts of things on different websites, don't just rely on one or two tests. Some websites or tools give the wrong results.
