Bursty Data on Sprint's 1X Network

I've been doing some speed testing with my Sprint Treo600 using the Palm program Bmeter (available at hexlet.com. What I understand this program to do is measure the effective speed as the device downloads 4 KB files, and it performs this download 10 times in succession.

I did this test 3 times in a reasonable signal strength area here in the SF bay area (two bars) during peak drive time (6PM). Here are my results (averaged over 3 trials).


iter	byte/s	kbps
1	172	1
2	2359	19
3	4061	32
4	5926	47
5	4730	38
6	5988	48
7	4454	36
8	5112	41
9	10313	83
10	5656	45


The whole test took about 40 seconds each time. I'm a little suspicious of the first iteration, as it might be a server issue more than a network issue. Even so, it looks to me as if it takes between 3-4s for the Sprint 1X network to get up to speed. This might explain why small web/wap pages have always seemed to load just as slowly (if not slower) over 1X as over IS-95A, even though large downloads clearly benefit.

Anyone willing to try this test using Palm devices on other networks? Eric, if you care to dust off the Kyocera 6035, I'm curious whether IS-95A also had a 4s lag.
