Hi
Thanks for good job aтв fresh ideas ! )
Are all 3 plugins compatible ?
Or no need any more to use MINIFY...?

Any idea price for CDN service ? keycdn.com 

Minyfy plugin really depends, it may or may not work.
For keycdn we paid $50 and it looks it should be enough credits for 2 years.

can you briefly describe usage of CDN ?, how to connect this plugin properly ? Do I need to link my JS,CSS routes with keycdn.com?

Also will be great if you can upload better quality of demo photo on OSCLASSpoint, not readable....

And what about banners - Pictures from Banner/ads plugin, can I use this data too

@Ivanko
You only setup CDN url in plugin.
As example, your base url is https://yoursite.com/ ... you replace this with your cdn link https://xy-abc.yoursite.cdn.com/
Plugin then automatically replace https://yoursite.com/ with CDN link on all item images, stylesheets (css) and javascript.
Regarding other resources (theme images, banners, ... whatever) you will have to manually update theme files / plugin and replace osc_base_url() with cdn_link() function.

Great !
Seems to be good plugin and idea as always!
The time has come to improve page speed !

Do you have some links with your websites WITH  and WITHOUT integration those 2 plugins ?
I want to see the difference in page speed by pinging from various location ...? 

@Ivanko
You can see difference for CDN just testing via i.e. tools pingdom site. Regarding Cache, you can clean cache and see difference in loading time (first time when page is uncached load time is not changed).

OK, just purchased both
Will live review after testing.

Sure let me know 

CDN is working good
Please check if that is all what required to setup as per picture, apart of manual routes set up or fine tune?

I see now all CSS, JS + pictures become linked with keycdn...

Open some item image and check what is its url. If it is not your site, everything is good

yeah, correct all URLs are mirrored to cdn now 
very good!
