I posted this elsewhere when I found it last year. Great read IMO. Be sure to have Adobe's Acrobat Reader installed on your system. The link is for a PDF file. Save it to your computer first if you want it to open more quickly of course.
Best,
Ron

?? Why would saving it locally make a difference?

Primarily because your processor doesn't have to time share the task of opening a file at the same time you are downloading it. If you have a very fast computer and a very fast broadband internet connection, you will notice little difference unless there are other prioritized tasks (programs, applictions) working in the queue or running in the background. Further, opening a PDF file utilizing a hyperlink via browser is inherently (by nature) slower than using the correct associated program (Acrobat "Reader") to open the file. You asked me what time it is and I told you how to build the clock. Anything else?... :roll: :wink:
Best,
Ron

+1. If you have a slow connection well...it's going to be slower. Not everyone have broadband, so if you want to open it multiple time you don't have to d/l it again. I guess if you read it in one shot, it doesn't make any difference.

I'm afraid this just isn't true. Modern machines(anything newer than about 2000 or even earlier) use DMA I/O for networking, so the CPU is doing very little work reading and copying HTTP. Anything newer than 2007 likely has a multicore processor, so this is even less likely to be true. As for opening via a browser vs acrobat, browsers themselves don't display the PDF's themselves, they use a plugin from Adobe.

Don't know and don't care about which is fastest, but that's a great article Ron - thanks.

If one is on a dialup or 3G connection, it think might be a tiny faster bit to have it cached locally the second time around.

Surely you guys believe in data locality, don't you? :poke:

The browser should cache it locally in any case.

It goes way beyond MapReduce. We do lots of interesting things to make sure that data is as close to the user as possible. But in this case, it isn't about getting the data close to the user or not. The data is going to get there at the same rate whether you download it first or open in it in the browser.
