I believe Dave is correct. To get the LFSEI, at least download of personal records and personal online stats from LFSW is required. But these requests are accompanied by other, such as LFSW hotlaps, and AIRW records plus hotlaps. This in fact makes 5 requests:
10.07.30 12:39:15 #1 C01P00 åir - Requiring LFSW OS data...
10.07.30 12:39:15 #1 C01P00 åir - Requiring AIRW VB data...
10.07.30 12:39:15 #1 C01P00 åir - Requiring AIRW VL data...
10.07.30 12:39:15 #1 C01P00 åir - Requiring LFSW HL data...
10.07.30 12:39:15 #1 C01P00 åir - Requiring LFSW PB data...
If just one unpaid LFSW key is used, then getting all the data will take almost 30 seconds, and even (much) more if there are other requests already queued!
There are two solutions to speed up requests. One is to use paid service. Put some money on your LFS account and specify in Airio CFG file that the service is paid for. My estimate is that on RR the monthly cost will be between 0.5 and 1 pound. I did a test, and month paid requests cost 3.5 pounds on AA demo servers, but they are rather a busy lot.
The other solution applicable for FULL and PROS versions is using multiple LFSW keys, which you may get e.g. from your teammates. Note that each much generate only one key and that key must not be used anywhere else, or requests may fail. (From this perspective generating multiple keys under one account is the worst you can do.) If you can use e.g. 5 additional keys, then all the requests will be done in 5 seconds, which is rather reasonable time. (With paid service the time is usually under 1 second.)
