interpreting image compression result

[pmeenan]

Going back in the test history to 11/8, it looks like this is the last result that worked: http://www.webpagetest.org/result/141108_RJ_JQ2/

I don't see any png's flagged and there are only 3 JPEG's that could be slightly smaller using lossy compressing (saving at quality level 75-85): http://www.webpagetest.org/result/141108...ess_images

Lossy compression isn't something that smushit does but to be honest, that isn't where you should be spending you time. The 10 seconds TTFB is where all of your time should be going. There are a few static images from that same test that also took > 3 seconds which is pretty much a smoking gun that the web server is either not configured/tuned properly or that the host is WAY overloaded (I don't see requests that slow very often, even on shared hosting).

If they can't figure it out and try to charge you to solve it I'd HIGHLY recommend moving the site to another hosting provider.
