it's because the toolbar notifies its googlebase about every site you visit (that has not been in your cache yet / that is fresh.. not sure about this exactly) however, assuming that you enter the index page of some site that you visit for the first time, you might have external stylesheet that is loaded, images that are loaded, and also a request to google containing the address of the page you visit (there were several discussions about this already, google will use this data to find sites to index that were not submitted) along with an id (your google id which also is contained in the google cookies)
so depending on the page (the number of images etc) the ratio of usual requests to requests+google request is x:x+1 (google's GWS/2.0 servers are pretty fast)

thanks--but i guess i still wonder about the fact that i haven't had this problem with any other configurations, and all of the factors you describe would have applied to them as well. The delay in loading pages is really quite pronounced, lasting 5 or more seconds on a T-1 connection. I don't think it's a hardware issue, as the pc is plenty fast enough browsing with advanced features disabled. it strikes me that there may be some software issue, such as conflict with Vshield, but I haven't found that anyone else reports such problems, so that seems unlikely.
