Linode vs Rackspace

Considering Linode SSD VPS so I got a 8GB server located in New Jersey to test. Run @eva2000 centminmod benchmark script and I'm puzzled by the much slower bandwidth from Linode compared to the Rackspace server (currently located in Virginia, same east coast US).

Oversold, overloaded server or network? Or perhaps Linode's bandwidth providers are just utilizing congested routes.

This shows that that the server/VPS/network is perfectly capable of achieving gbit speeds, but why it's not getting those all the time is anyone's guess.
 
@WSWD, check the trace routes & ping latency. I'm betting Linode doesn't have direct connectivity to some of those locations where as rackspace may have.

It's still horrendously slow, even taking that into consideration. This is especially true when you look at the Cachefly results. Basically ~22mbps? WAY too slow. There is something very wrong with the results that have been posted. There is absolutely no way in hell that the east coast to west coast (i.e. San Jose) should ever be <1 mbps. You would get better speeds from the west coast to Europe or Asia.

I don't know what the problem is, but there is most definitely an issue somewhere.
 
TBH, I'm not sure why you care. Linode and Rackspace are really aimed at different markets. If all you want is a server capable of running a forum about some special interest group with relatively low concurrent users at minimal cost, then you go Linode, which runs XF just fine. If you want a really robust system with bells and whistles to support a mission critical forum, but is going to cost you a bit more then you go Rackspace.
 
Linode was dead slow when i tested it. Their cpu speed is VERY volatile. It seems you do not get a dedicated cpu core there.

Are you referring to the 16CPU, 48GB RAM, 1152GB SSD space for almost $500/month that you tested?

ROFL!! You can hardly compare the performance of what is really a beefy dedicated server costing $500/mo. to a basic 1 or 2 core VPS through them. That's just an extremely silly comparison to make. I highly doubt @Marcus was running that configuration, or else yeah...he probably would be getting great performance.
 
I tested the 40 USD plan around two months ago. Their CPU cores were highly volatile. I tested with both my xenforo community and with the php test program that's included within the Zend package (as much as I remember).

On amazon I always got the same results everytime I run the test, I always got the same results on my former dedicated server. On linode I got highly mixed results. I showed the linode team my results they didn't care about that. You can also find several topics about huge differences in cpu speed at their official linode forums.

My community is rather small, so I focus on giving each member the same very fast experience. It really doesn't make any difference whether I would have 2 or 12 cpu cores. My community now runs on 4 cores at the same speed as with 12 cores before, the two cores now are faster and not all cores are needed at the same time.

My current Amazon setup scales indefinitely, meaning that when my server is maxed out at defined CPU level, more cpu core web servers are activated. I could run now like 1000 cpu cores, they are just not needed. If you really care about cpu speed you should have dedicated access to the server to set up cores to performance status and not on demand, but that's another topic.
 
strange then as that's exact plan I am on $40 Linode 4GBVPS for my forums https://community.centminmod.com/ (forums are 4 months old and been with Linode since day 1)

I've tested all the Linodes from 2GB all the way up to 48GB FYI https://blog.centminmod.com/346 :)

@Marcus what Amazon plan you on ? Would like to test it out for myself :)

FYI, php Zend test package is single threaded so you won't scale with number of cpu cores ;)

here's php Zend/bench.php and Zend/micro_bench.php tested capturing the cpu utilisation too, it only ever uses 1 cpu thread = 99-100%

Are you referring to the 16CPU, 48GB RAM, 1152GB SSD space for almost $500/month that you tested?

ROFL!! You can hardly compare the performance of what is really a beefy dedicated server costing $500/mo. to a basic 1 or 2 core VPS through them. That's just an extremely silly comparison to make. I highly doubt @Marcus was running that configuration, or else yeah...he probably would be getting great performance.

I was speaking towards the volatility comment as I've tested Linode 2GB to 48GB and cpus do scale with the right multi threaded utilising tests
 
@eva2000 your results are showing really dedicated cpu cores and a stable performance. It looks good. Unfortunately I didn't have that experience.

Here are the results from my live server.

There are some more topics about that, this is the first I found now:
https://forum.linode.com/viewtopic.php?t=10815&p=63029
 
those numbers look well within a margin of variance between runs to me which would be normal - especially if it isn't an idle server but a live production server with active usage :)

and that post is for older linode plans with older cpus the Xeon L5520 is old and much slower clock for clock than the new linode Xeon E5-2680v2 used nowadays and Amazon E2 now uses E5-2670v2 or E5-2680v2 too

FYI, the PHP Zend bench test is single threaded and depends on cpu clock speed as well.

  • Xeon L5520 is base clocked at 2.26Ghz with Turbo boost at 2.48Ghz
  • Xeon E5-2680v2 is base clocked at 2.8Ghz with Turbo boost at 3.6Ghz which is almost 50% faster at single threaded Turbo boost speed.
  • Not to mention Xeon E5-2680v2 is like at least 4 generations newer than Xeon L5520 and performance clock for clocker is multiples faster to add on to that higher clock speed
I posted my Linode 2GB staging server benchmarks at https://community.centminmod.com/th...-for-centmin-mod-lemp-servers.1298/#post-5956 as well

for PHP Zend tests they look like yours which is close to expected give that it's single threaded test and Linode all VPS now use Xeon E5-2680v2 anyway

I wouldn't use PHP Zend test as the sole factor to determine performance anyway :)

My cores are part from Intel Xeon E5-2670 v2. Most likely with counsetting: on demand and not with cpu setting: on performance and not with turbo boost enabled.

Some more data from my memory.
Load time of my modded xf forum start page within debug mode in:
Current setup: 0.18
Linode setup: 0.20-0.38 (mostly at 0.34-0.38)
Former 12 core oone year old server: 0.12

Which php do you use? I use php 5.5 from the standard repository. Your setup is faster. If the php releases are the same then the ..80 xeon must be much faster.

Linode was dead slow when i tested it. Their cpu speed is VERY volatile. It seems you do not get a dedicated cpu core there.

Not sure how Linode is doing it but one of my other providers for example is selling threads not cores and only deal with Xeon's. So an 8 core 16 thread Xeon VPS host is serving up 16 single core vps's or 8 dual core so on and so forth. The particular provider I have experience with under demand they always perform. But with 2 threads I expect at least the performance of a single core in comparison to dedicated hardware (leaving single versus multithread loads out of the equation). With 1, if other clients are loading the server pretty hard I expect it to be crap.

But running window's servers on the one provider I always benchmark against my i5 at home.

currently using PHP 5.6.0 but old numbers with PHP 5.5.16 at https://community.centminmod.com/threads/community-centminmod-com-journey-for-speed.3/#post-5256 (PHP-FPM via my Centmin Mod LEMP web stack - you can see my source compile options I use at http://centminmod.com/phpfpm.html)
