Q:

Running LESS server-side vs. client-side

What are the advantages / disadvantages to running the LESS framework client-side vs. server-side? Does page load time take a hit if you run it client-side?

A:

On the server, you have to take more care with your cache control headers and you sacrifice a bit of CPU power.
On the client, it breaks if JS isn't available.
(For your production systems,) do it at build time and just serve up static CSS. That's efficient and reliable.
