10G dedi vs 1G - can you feel the difference?

bchot

I've only had 1G dedis until now. I have a few, from Hetzner mostly, and to me 1G feels fast enough even when 2 of my workhorses average 300-400mbps.

if I ever were to go ahead and try 10G uplink server, would I feel the difference? DO YOU feel the difference? can anyone really say that switching to 10G from 1G uplink really improved things for them?

Absolutely nothing changes

If you drive a family car and the speed limit is 120, would you feel the difference if you go
on a German autobahn without a speed limit?

isn't it a great way to answer a question with .. wait for it... a question?

I personally think all newer dedicated servers should at least come with a 10G NIC. Any that don't, and with no upgrade options, the provider is likely running old 1G rack switches. I greatly prefer companies that include a 10G NIC even if the port is limited to 1Gbps (but having 10Gbps inbound and 1Gbps outbound is even better.) Being able to easily upgrade if needed is useful. Plus the 10G NICs are just better performing under high load even with lower port speed.

I want a 800Gbit port on a C2350 so I can download my Linux iso's in a millisecond. Any deals for $7/yr?

Unless you're approaching saturation of the 1G port, it will be indistinguishable from 10G, 40G, or even 100G. If you aren't serving large files to a large number of clients simultaneously, you're never going to see any improvement.

mmmm I like the illusion of speed on my $7/year idle server

Is that because it's 10G or because it has a bigger internal buffer and thus needs to raise fewer interrupts?

I suspect that any 10G NIC is going to have a pretty big internal buffer to be able to handle 10G speeds reasonably, so with interrupt coalescing, even at 1G it's going to be able to store more internally before it's forced to do a DMA transfer and raise an interrupt. But this is just my guess. I doubt the impact would be appreciable.

no, bigger mean better.

what you said. more queues, big buffer, more pps at same bit rate, better cooling than most onboard 1g nics (referencing pcie cards.) But to most people does it matter no, the joys of having to eat DDoS attacks daily.

It impacts how fast we can move our stash during a raid
