| A file isn't saved to the server until you post your message, hitting the "Post Message" button. I suppose when you preview it the message is saved into memory briefly while it serves you the page, but that doesn't impact things. Calculations are done fast on servers. I'm building something right now for a media organization to look through best track and model data and it took 19 minutes on my home computer to process a text output that was 1.02 gigabytes. And that was just to prepare for the calculations that get really complex. I couldn't do that initial processing on a server, because that kind of thing would cause problems. Then again, the calculations for the model system are really complex. For system integrity, the server that HurricaneCity is only allows processing for 1 minute. That may not seem like long, but the data it crunches in that amount of time is incredible. But due to so many storms, I had to remove the East Pacific storms because there was just so many numbers being crunched. I wouldn't be surprised if it's doing a million, or even millions, of calculations when it's calculating model error statistics and creating all the model data for Google Earth and Google Maps. When you view the model error data on a page in the model system it is stored in a file and the page is created from it. It would be too much processing to do the calculation when you load the page. When I recreate all the model and best track data in history I do it offline as the processing takes like a day and in 2015 involve creating over a quarter million files and was 6 gigabytes of data. I would imagine when I do that it involves many trillions of calculations. And the recon system has over 100,000 files, but it processes a lot faster. I recreated all the maps a few days ago and it may have taken less than an hour. |
