Some Random Testing on the Road Runner Speed Restriction
Here are a couple more links discussing the issues.So the other night at 2am I decided to perform some maintenance on my employer's email and web servers (thankfully not on a Time Warner link). Both of the servers are VMware server virtual machines and about every quarter I compress them up and transfer them offsite (generally to my file server at home), they're then burned to a DVD and stored in a safe place offsite. Nightly backups take care of the files and database changes which are transfered to a NAS at the provider that is supposedly secure and backed up.Down to the annoying problem!A lot of my work and research is done around security and a common practice is getting your ssh server off the standard port 22 to avoid the annoying brute force scripts and worms traversing the tubes. There's a number of other things I do in terms of ssh, but you get the gist of it.I go to scp the compressed files and I get 50-80K/s, never a glimpse of anything over 80. The transfer used to take 1.5-2hrs and the files this quarter are only 300MB larger, but this time it's going to take 13hrs! So with my impatience I cancel the transfer and proceed to push the files over my SSL VPN (i'm thinking well tcp/443 HAS TO BE FASTER), so the transfer takes off blazing about 500K/s woohoo. I look back and right as the file hits 15MB it slows down to 50-80K/s, stalls, times out, 30, 20, 80K/s. Great. So I think hmm maybe b/c it's encrypted and only started by a initial HTTP method type of connection (that's obviously done with now) that it thinks the transfer/connection is "malicious" (or whatever RR/TW calls it). So I try one more thing before reverting to a PPTP/GRE tunnel. I toss my sshd of my hosting servers on tcp/80, same results, blazing until it hits 15MB, timeouts, random slowness. I reverted to the PPTP tunnel that took about 9 hours, it initially started about 300k/s then slowed down to 100k/s. This could very well be b/c my VPN connectivity to my hosting provider uses Cogent.
