Agreed - 8 days 14 hours!  At the current rate of growth the
delay will be 9 days before tomorrow.  Here are the latest
numbers I have:

Upload Time           Time Processed      Elapsed Time
=======================================================
2012/11/23  18:00    2012/11/27  00:43    3  06:43:34
2012/11/28  22:32    2012/12/05  02:08    6  03:35:10
2012/11/29  18:38    2012/12/06  05:10    6  10:32:20
2012/11/30  00:58    2012/12/06  18:24    6  17:26:26
2012/11/30  17:04    2012/12/07  17:28    7  00:24:16
2012/12/01  08:20    2012/12/08  19:09    7  10:49:15
2012/12/01  12:30    2012/12/09  01:10    7  12:40:49
2012/12/02  05:00    2012/12/10  19:31    8  14:31:29

The delay is growing out of control - between 12/1 and 112/2
there were 2.5 times as many QSOs uploaded as LotW processed
and LotW has been processing an *average* of 11,000 QSOs per
minute or about 264,000 QSOs per day based on the information
on the home page.

If one plots a trend line, the delay is growing exponentially.
The trend indicates a file uploaded *today* is not likely to
be processed *for more than five weeks* based on the current
rate of growth in the backlog.  Based on the processing time
for files uploaded at 0500z on 12/2, there were about 2.25
million unprocessed QSOs in the queue at that time - and that
was 48 hours *after* the deadline for submitting CQWW CW logs.
With the trend in growth between 11/25 and 12/2, the queue could
hold as many *10 million* unprocessed QSOs (although that is
unlikely)!

I know the folks in Newington are saying "trust us," but their
performance - and complete failure to provide *current data* -
particularly the failure to provide accurate current status on
the size of the processing queue - makes trust very difficult.

Unbelievable processing times. Delay keeps growing. Up to 8 days just a
few minutes ago. Love the program/system but unless they can come up
with a way to handle the load, then it will die on the vine.......
