Gzip VS Deflate

Hi

 

 

I'm going to set up compression feature for a really hot site (banking).

 

 

Reading at the web it seems to be more interesting to use deflate instead of gzip, but I guess that this idea is based on web server performance.

 

 

We're playing with the LTM avoiding the hard work at the web servers so maybe is better to keep gzip as prefered compression method.

 

 

Any idea ¿? which one do you like?

 

 

Thanks! ;o)

    deflate should provide more compression but require more resources. Ultimately the only way to tell which is preferred is through rigorous testing or even going live.

     

     

    You may well find that on modern broadband connections there's very little benefit is compression (but again it depends on what you're compressing!)

     

     

    From an f5 perspective, you need to set the compression level to '1' to ensure it gets done in hardware (any other value it gets passed to software).

     

     

    good luck!
