To some degree I suppose that is true, but it will at least tell you whether you have a serious connectivity problem from your machine to the site - either confirming (or eliminating?) that as one possible source of slow page loading. I only suggested it since others (myself included) had "good" repsonses.
That said, your traceroute doesn't look too bad; I'd be a little concerned about hop 3 at 202.5 ms, and if that is consistent, I'd talk to my ISP - maybe they have a "borked" router. Standards of acceptability vary greatly among ISP's, but I think your "slowest" links should be not greater than 50 ms for the ISP to be said to have "reasonable" latency.
Which brings up the "sluggish" hops 8 and 9 - at Dreamhost. While I think that should be better, in the "real world" I can't see that contributing much to a delay in displaying the page. I suppose it could be indicative of a DH network issue that is only magnified "invisibly" by DH having to run around within it's network to retrieve the MySQL data from the MySQL servers in order to display the WordPress page, but then the rest of us should also be seeing "bad" load times, and that doesn't appear to be the case.
