      Current state of vpsBoard   02/04/2017

      Dear vpsBoard members and guests:

      Over the last year or two vpsBoard activity and traffic has dwindled. I have had a change of career and interests, and as such am no longer an active member of the web hosting industry.

      Due to time constraints and new interests I no longer wish to continue to maintain vpsBoard. The web site will remain only as an archive to preserve and showcase some of the great material, guides, and industry news that has been generated by members, some of which I remain in contact to this very day and now regard as personal friends.

      I want to thank all of our members who helped make vpsBoard the fastest growing industry forum. In it's prime it was an active and ripe source of activity, news, guides and just general off-topic banter and fun.

      I wish all members and guests the very best, whether it be with your business or your personal projects.

Raspberry PI 3 Now Launched!

Hmm, I checked my smallish standard household fridge with a Kill-a-watt meter and found it uses 150W when the motor is running and basically zero otherwise; the motor runs about 1/3 of the time, so 50W average.  My mom's fridge is full size, maybe 2x the volume of mine, so I guess 100W but haven't measured it.

Has anyone else played with the new RPi3 and seen any different results as far as the range and power of the wifi?  I am gonna test a few more things, I don't want to give up yet!  There must be some tweak I am missing, I feel like I am just too close to have it be attenuated as much as it seems......

Ahh the way it used to be.. @HalfEatenPie looks like one of your cousins is hanging out with a super star, should ask him/her to get autographs for us all! :D

Cheers!

Cute.

I haven't mucked with the 3 yet... Taking it you are having wifi performance issues with yours?  Care to describe?

I just upgraded to a Pi 3, stuck on the back of the telly with OSMC as media centre. I've also got a 1G hard disk and 2xUSB sticks attached for local file management and remote sync / backup. It also runs two websites, acts as a 24/7 torrent / soulseek box, DLNA server, and I test my Ruby scripts on it. It handles all this like a champ. Fantastic value for money.

I also believed that 2.5A was required, but I've had no problems so far using the same 2A supply that ran the pi2. There is also a setting that will boost the current going to the USB ports.

Okay, so I must admit, I finally figured out my Wifi issue, and I am somehow happy to say it was my fault.  I have two access points I use here, one for my security stuff (wifi cameras) and one for the house (anyone in the house) and I had placed this on the security network.  Unfortunately this meant there was very little wifi bandwidth available because the three cameras broadcasting on the access point are taking everything available (data being relayed to the monitoring server constantly).  Finally after some good sleep and wide eyes I was doing some testing and temporarily disabled my cameras and what do you know, went from 1Mbit/sec to 40Mbit/sec in a blink of an eye. So it is at this point that I facepalm and say, ... "oops! Hey RPi3, lets have another go at this...no hard feelings, k?".

@drmike you had asked for my tests, well here is my results after some testing showing the issue I was seeing: http://paste.ee/p/1tFuq

You can clearly see the difference between with the Wifi cameras on and with them off....

Also, placing it on my other wifi while it is also busy also yielded much better results.  At the time I just didn't get around to testing it. I guess it is time to retire the 'Jump to conclusion Mat' it doesn't seem to be working out for me very well......

 

Cheers!

Neato :) How did you get it to mount there?  Buy a VESA case?

Soulseek - tell me more about that - new to me.  Is it a network for sharing or?  Impressed with all you have this box doing.  Doing all while running OSMC?

The USB higher power supply compatibility was just to deal with higher power draw devices that would undervolt the Pi and cause issues or just not work at all.  Not needed unless you are running such.

Wifi noise can be really serious.  Try bumping everything to different channels wide apart.   I have issue with my high powered AP if I get close to it devices fail entirely.... several feet away in fact.

Definitely interference / bandwidth issue with your setup - likely on neighboring or same channels.

Good work debugging this - lots of people on constant store returns on stuff cause of simple issues like this.. and large apartment complexes have to be horror these days.

So many ARM topics I forget which one I've been posting to anymore...

I got my ODroid C2 and my PINE64 and I must say that ODroid is the clear winner among all of my devices so far. I haven't even tested the C2 outside of a few DD and iperf tests but so far it blows away the competition from those 2 tests alone. The PINE64 is a complete disappointment but I'll wait for the development to mature more before completely tossing it in the garbage. Right now the 1Gbps NIC cannot hit 1Mbps if it's life depended on it with the recommended Debian OS making it impossible to use for anything short of word processing. It's also very picky on displays so if your TV/monitor doesn't work out of the box you'll need to wait for a future update and if you think you're going to use this headless then think again, without setting up the root password SSH will actively refuse connections so you'll need a display just to enable SSH (unless you want to guess where things are with a mouse and keyboard and no monitor). Installing vim and iperf were painful to say the least at sub 10Kbps download speeds. Some people have fixed it by forcing the NIC to run at 100Mbps instead of auto-negotiate but I haven't had any luck and if you set the NIC to 1000Mbps it disables itself so it seems like it can't run at 1Gbps even if it wanted to.

I did get to play around with all of my devices the past few days though and basically anything with the word "Pi" in its name (Raspberry Pi, Banana Pi, Orange Pi) aren't worth the cost of shipping when compared to any of the ODroid devices. iperf tests are pretty bad across the board for them and the CPU load when hitting sub-500Mbps speeds is sad. I'll run some other tests today probably and report my findings.

EDIT: Was reminded the following as well:  "Longsleep said he provides a new kernel over the weekend so remember to run the update scripts to benefit from latest fixes"

From the people I have talked to they suggest this image -- it should get you gigabit nic. There will be some other images coming soon, for example here is am image that includes A64 u-boot (not BSP) :

https://github.com/apritzel/pine64/commit/e7ca16dcabf63d18f7e17ab88718df9049eee174 

You should be able to use your own kernel/rootfs with it.   I imagine with the amount of boards that went out they are working to build more working images as well.  I didn't go for the pin64 cause I was concerned about support for it, though they have spawned a bigger following than I had originally expected so things are slowly getting done.

my 2 cents.

Cheers!

I got mine last week, I still prefer the ODROID-XU4 though (of which I now have 4 sitting on my desk). Its useful however for applications that dont need as much power, or where the fan noise would be problematic.

I love the Odroids... Still have an older one running my gateway and VPNs.   But nothing beat the pokey Pi's on just working and community. Always bumping into stuff for RPi, not so with other boards.

Someday I'll find someone with an XU4 to sell me.  Harder model to find used than many of their others.

For now I am trying to find some time to muck with Cubieboard2's.  Gbit on it actually puts out about half of Gbit, which I'll take (other boards are just slow / BS).
