Should I let my provider know?

I think my old host put me on a 10 Gbps port, because my new host gave me 1 Gbps Port and its 1/10th of it's speed. I also noticed fast I/O speed on my old host, which was not using SSD. Both are in California.
Am I obliged to tell my old host they may have given me a 10 Gbps port and SSD features, when they promised less? Or is it standard for host to sometimes give better performance than ordered? I am new comer so, not really sure what to do.
Weird though, I haven't logged onto my server for several hours and I didn't restart it, but it says 13:40 up time....
Yeah sure, I have better hardware at new host and location is same, but my websites load much much slower. Maybe it has to get to the new host, so I'll give it some time.
Comments
New hosts bandwidth is very low. Contact them. Old host is on 1Gbps.
Okay, good. Phew, I thought I was cheating my old host.
I will let my new host know there is problem with bandwidth.
That speed DC is pretty low.
@Zeal where is the VPS located?
LA, California. Bandwidth Provider is Colocrossing.
That SSD is also very slow
What should I expect for SSD?
Also was your old host a VPS:
Number of cores = 1???
Both are actually VPS.
@Zeal - depends on the SSD. If its some old Sandisk/consumer thing then probably about that.
To give you a comparison, this was run on a L5520 server with Samsung 840 Pro 240GB SSD (under heavy load with MongoDB instance running on it):
I/O speed : 269 MB/s
E5405 for a VPS server is a little crappy
Since the CPU is a little crappy, the SSD is probably old aswell.
Interesting, so the type/model/brand of the hardware affect the performance.
There is more to it than I originally thought. (RAM quantity + Port Speed + SDD = Win)
Atlanta was the one with problems, and that was fixed a year ago.
Stick with the old server that appears to have a gigabit connection, the new one looks like 100Mbps on some steam powered server
Yeah, I'd get away from that new host ASAP if I were you.
Okay, fine, I will be the one to ask some of the more logical questions:
1. is this KVM, XEN or OpenVZ?
2. If it is KVM or XEN have you tweaked the TCP window sizes and other settings?
(If not, please see http://lowendtalk.com/discussion/25317/fixing-network-speed-in-kvm)
3. If KVM are you using the e1000 or virtio driver?
Using the realtek driver will usually show substantially less throughput, even if the host supports full gigabit.
4. If KVM are you using the virtio driver for Disk Driver?
This will in some cases greatly effect your disk IO throughput.
Also, just a note if its OpenVZ regarding the uptime, a lot of hosts have recently restarted their OpenVZ nodes as last week there was a vulnerability released, so your vm may have been rebooted during those updates.
If both are OpenVZ, then it looks like the new host is likely overselling more than your old one as the specs across the board seem lower with both network and drive speed.
Just to note though, a 160MB/sec io throughput is not horrible, in fact you should be able to do most ordinary things in less than 60MB/sec IO space unless you are running some type of database that requires a hell of a lot of reading and writing where the added speed would help. So really the bigger concern here should be the network speed and not the IO speed.
Cheers!
LA was never 10/100, we deployed it from day 1 with FCX648s.
Dallas got upgraded to all gigabit Brocades almost a year ago.
