Hello Tom;           I do realize that the hardware upgrade will help the throughput, but using these numbers - 2250 files with 300 QSO (approximately) each in 24 hours is the same as a average processing time of 128 milliseconds per QSO record, which would seem high.....hopefully the hardware will provide an improved situation.          Look forward to seeing you in NLO                           73, Kermit W9XA --- On Thu, 12/27/12, Tom Frenaye <frenaye@pcnet.com> wrote: From: Tom Frenaye <frenaye@pcnet.com> Subject: [arrl-odv:21345] Re: LoTW To: "arrl-odv" <arrl-odv@reflector.arrl.org> Date: Thursday, December 27, 2012, 9:23 AM At 09:54 AM 12/27/2012, G Widin wrote:

The emptying of the queue cannot be computed because we don't know the input rate.  You must assume an input in order to be able to solve the equation.  Also, something must be assumed about the nature of the material being processed--probably that it doesn't get more or less computationally demanding (technically, that it is stationary).

Based on the number of files reported on the home page of LoTW for the last couple of days, they are processing roughly 2250 files per day.    The average file has around 300 QSO records based on the queue information. The progress in reducing the queue has been agonizingly slow...    I understand the new disk drive array has arrived in Newington and they are working to get things ready for the upgrade.      Tom ===== e-mail: k1ki@arrl.org   ARRL New England Division Director  http://www.arrl.org/ Tom Frenaye, K1KI, P O Box J, West Suffield CT 06093 Phone: 860-668-5444 _______________________________________________ arrl-odv mailing list arrl-odv@reflector.arrl.org http://reflector.arrl.org/mailman/listinfo/arrl-odv
