Hi,

I've just started to look at Page Speed to aid in the optimization my Site.

Looking at the 'High Priority' recommendations, I'm unsure whether I need to address them or not:

1. Enable Gzip Compression - lists certain css files (and a lightbox .js file) as being able to benefit from compression. This seems strange as I have gzip enabled in Admin. btw, websiteoptimization.com recognises my gzip.
2. Leverage Browser Caching - css and gif files listed here are 'missing a cache expiration' ...????
3. Parallelize downloads across hostnames - again, refers to css and gif files on the page.

Any ideas as to whether I need to address these and if so how?

Using 1.3.8a

thanks

Simon
