How to make website load faster and cause less load on the webhosting server? Do you have any tips?
So far i found a few page speed analyzers that can advice on what to do to increase website speed:
1. https://developers.google.com/speed/pagespeed/insights/
2. http://www.websiteoptimization.com/services/analyze/ (good advices on the bottom after test result)
3. http://www.dotcom-monitor.com/WebTools/website-speed-test.aspx - load times from different GEO locations
Examples actions to decrease website load time:
- optimize images to be as smallest in data size as possible - try these optimizers: http://www.imageoptimizer.net/Pages/Home.aspx ; http://tools.dynamicdrive.com/imageoptimizer/ ; http://jpeg-optimizer.com/
- reduce number of page elements. Example, use "CSS sprites" OR use so called "HTML maps" if you have static images in a row to combine it and assign them links (multiple links from one image) here are ImageMap generators: http://imagemap-generator.dariodomi.de/ (click first corner, then click second corner and click New Area. repeat)
- Add images into so called data:uri (http://dataurl.net/#dataurlmaker) (embed images into html code not needing to have image file)
- miniffy javascripts & css (http://www.freeformatter.com/minifiers.html)
- prevent javascript delaying load of webpage by setting async attribute to it, example: <script async src="my.js"> OR move javascript to the website footer OR embed small javascripts directly into the webpage code (see how (https://developers.google.com/speed/docs/insights/BlockingJS))
- another ideas how to optimize site here (https://forums.digitalpoint.com/threads/which-webserver-values-have-biggest-impact-on-website-load-time.2718231/#post-18955458)
Add this to .htaccess file (it should instruct website visitor webbrowser to cache mentioned elements and dont request them from your server)
## Browser caching - Tell browser to cache and not download again ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 month"
ExpiresByType image/jpeg "access 1 month"
ExpiresByType image/gif "access 1 month"
ExpiresByType image/png "access 1 month"
ExpiresByType text/css "access 1 week"
ExpiresByType text/html "access 1 day"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 month"
ExpiresDefault "access 1 month"
</IfModule>
## Browser caching ##
Add this to .htaccess to compress content sent to website visitor (save datatransfer, cpu and serve site faster)
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</IfModule>
Test whether your site output is compressed: http://www.whatsmyip.org/http-compression-test/
If having wordpress, or other CMS, search for "Cache plugin/mod" which can cache some dynamic elements of the webpage into static one decreasing load on server and time to serve content
