page 'render time' can mean two things. It can either mean the time it takes PHP to process a page in which case your numbers look pretty good to me. It can also mean the time it takes a browser to render a page once PHP has delivered all the HTML to it (this is something you can try to calculate with Javascript or use Firebug + Firefox or something).
If those are PHP processing times, they look pretty good. I've been taught that a well-designed web page should be about 10k and load in about 1 second. Of course these days pages are 10 times that size but still load in approximately 1 or 2 seconds. It probably takes an order of magnitude longer for a page to be transmitted over the internet through all the intervening machines than it does PHP to process the page and generate all the HTML.
On the other hand, if your page just says 'hello world' then the times don't look that good. It sort of depends on what your expectations are and what your code is doing.
