First load is slow

Hi

I carried out this test:
http://www.webpagetest.org/graph_page_data.php?test=140425_GM_KRR&medianMetric=loadTime

Would you have any idea as to why the first test is always slower?

The main delay is always Time to First Byte, but always only on the first run.

Any help is appreciated.

Thanks

John

The first run is priming the caches on your server (database, filesystem, etc) so the next runs benefit from the server-side caches.
