Hahaa! I made some tests.
I took the old pallokorva.org(the one you see now) and put it head to head to the newest development version running elsewhere in a speed competition where the major criteria for winning is: How long will it take after typing in the address before I can read the text content of the page. The results are shocking. Dare I even write them down.
For the sake of getting some actual difference between the two I throttled the 20Mbit/sec adsl line down to mimic an old 11kbps modem(Of course it doesn't do similar latencies, but at least they were consistent over all test runs.) and emptied all caches. The php side has not been optimized in the new version in any way, so it played no role in the results.
