Salut!

Foloseste cineva arhivarea gzip, pe server?

Cum functioneaza? Reduce mult timpul de incarcare a paginii? sunt si alte avantaje... dezavantaje

Mersi

Gzip iti comprima site-ul (cod html, css, javascript, etc.) si iti poate oferi timpi mai buni de incarcare.
Pentru a putea folosi arhivarea gzip trebuie sa ai instalat mod_gzip pe serverul de gazduire.
 
What is gzip compression?
When a user hits your website a call is made to your server to deliver the requested files.
The bigger these files are the longer it's going to take for them to get to your browser and appear on the screen.
Gzip compresses your webpages and style sheets before sending them over to the browser. This drastically reduces transfer time since the files are much smaller.
In terms of cost versus benefit, gzip compression should be near the top of your page speed optimizations if you don't have it setup already.

How does it work?
Gzip is actually a fairly simple idea that is extremely powerful when put to good use. Gzip locates similar strings within a text file and replaces those strings temporarily to make the overall file size smaller.
The reason gzip works so well in a web environment is because CSS files and HTML files use a lot of repeated text and have loads of whitespace. Since gzip compresses common strings, this can reduce the size of pages and style sheets by up to 70%!
Gzip has to be enabled on your webserver which is relatively straight forward.
When a browser visits a webserver it checks to see if the server has gzip enabled and requests the webpage. If it's enabled it receives the gzip file which is significantly smaller and if it isn't, it still receives the page, only the uncompressed version which is much larger.
