Anyone knows whats the clock speed for each virtual cores? Isn't that a relevant and important information?

For instance if the previous virtual cores were all 1ghz and new cores are all 500mhz, doubling the cores won't do much good if you don't know their clock speed.

I was critical of last Linode's NextGen post discussion, because I didn't think upgrade was impressive compare to others, but this is one is a nice bump, memory is probably what most people will care about more though. So maybe next refresh is the memory?

Just rebooted and made cat /proc/cpuinfo and the and its 2.27Ghz, so the last of the 8 CPUs is

processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU L5520 @ 2.27GHz stepping : 5 microcode : 0x11 cpu MHz : 2266.746 cache size : 8192 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu de tsc msr pae cx8 cmov pat clflush mmx fxsr sse sse2 ss ht nx constant_tsc nonstop_tsc pni ssse3 sse4_1 sse4_2 popcnt hypervisor bogomips : 4533.49 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management:

That is the old 4 core cpu they have been using. We will probably have to wait some weeks before this all takes effect.

Pretty sure just reading the post answers this, "Linodes will start landing on NextGen hardware in the next week or so".

The post is a bit confusing, though, because well before you get to the line that you quoted, the article states:

"And we’re upgrading all Linodes to 8 cores! Right now. As in all you need to do is reboot to double the computing power of your Linode. By the time the host refresh is completed the average Linode will be running on hardware that is less than 1 year old."

I, for one, thought that it was ready now after reading that. In fact, from the comments, it's clear that for some customers, this is in fact ready:

"BizzarTech: Rebooted my 1024 and moar cores!!! Thank you!!"

No, the move to new hardware and increase in the number of available cores is separate. If you reboot right now you'll get access to more of the 'cores' on the host system (though I suspect they're really just "threads" in Intel terminology). But you're still running on the older L5520 hardware.

I rebooted and confirmed; indeed the older L5520 is still the processor being used on my particular linode:

This is from a plan that is less than a week old:

I just rebooted one of my Linodes, and I got this:

Edit: I should perhaps mention that this is a 512MB Linode, on the off chance that it makes a difference.

I rebooted mine as well and got @ 2.27 GHz, so I guess that they probably haven't gotten to your server yet.

> Powering our NextGen hosts are two Intel Sandy Bridge E5-2670 processors. The E5-2670 is at the high end of the power-price-performance ratio. Each E5-2670 enjoys 20 MB of cache and has 8 cores running at 2.6 Ghz.

> We limit the number of Linodes placed on each host machine. We also only place one plan type on each host. In the worst-case scenario, you're splitting CPU time evenly with your fellow Linoders, but are still able to use the full potential of the host if others are idle.

> So maybe next refresh is the memory?

Probably - according to their FAQ it looks like each host has about ~20GB of memory which is pretty small these days.
