Older nzb files download slower?

Postby rocky510 » Sun Dec 14, 2008 1:50 pm

hi

im a giganews user and i was downloading a nzb and normally they will max out my connection

but today i got a file and it was about 234 days old or so and my connection is jumpy like at 500kb/s to 200kb/s nothing wrong with the speed just wanted to know if u download older files will the speed be a bit slower?

Yes, it's normal to see the speed fluctuate when there are lots of missing parts due to the age of the post. 234 days is pushing it a bit, even for Giganews. I find that posts of around 210 days or less have good retention and speed. Above that, you can expect things to get a little patchy at present retention levels.

That makes no sense at all :-S , no older posts will not be slower , regardless of missing parts , actually it would be "faster" because there is less to deal with , less overhead etc etc. one of the largest performance impacts (there are 2 ) is 1> routing /peering . and 2nd > SSL or not , SSL will be slower due to the nature of the protocol , it establishes a key at the beginning and end of each part . This typically can slow down - 3 - 30 percent of the max. ( I would know ...... I have supported 3 out of the big 8 usenet companies for about 6 years professionally) .

Well Rocky...

I noticed a decrease with Giganews...but apparantly it wasn't Giganews, it was my ISP doing some 'upgrades' in the area starting on the 14th of December in the Humboldt area of Saskatchewan...apparantly it decreased the speed to about 1700kbps from 5000kbps. So, perhaps check your speed from your ISP...maybe something similar is taking place..or if you are from the same area...then there ya go :D

Actually he could be right..
just like older files on BT/ed2k/Gnutella have fewer souce oder nzb's can download slower?

Well, NG's aren't susceptible to the same problems as P2P...there isn't a number of "seeders" there is only 1. Giganews hosts the files on their server racks and is as easilly accessible as any other file. You request the download, it just locates it and tosses it down the line. It doesn't matter if there is 1 or 1000 people downloading, new or 200 days old...it would download at the same speed.

P2P requires sources to host the files, the more people hosting...the faster you can download it - in theory.

No problem, I understand you are new to that whole aspect and was just pointing out what I know :)

Newsgroups suffer the other problem: "Sudden Death" syndrome. Once an article has expired, that's it, it's gone forever. Depending on your newsserver that can be anything from three seconds for a 'free' server to 240 days for GigaNews. In that respect newsgroups are not good places to look for older or rare material.

Nad if the Server doesn't use RAID, or have backups...whoosh...a server crash would be deadly...right?

Thankfully, your premium servers are backed up to the nuts...Giganews would be running a VERY sophisticated backup system...so thankfully, a server or drive crash would probably remain unnoticed by most - if not all of their subscribers.

And yes, there is the 'sudden death' syndrome... but if a post goes away due to length past the retention...then just ask somebody to upload it again. There are many requests posted all the time...I've personally never had a request answered...but I've only put out 3 :D
