@uptime said: The solution turned out to be switching to BBR flow control on my end

I probably missed it, but where was "your end"? On your VPS at UltraVPS?

Added to /etc/sysctl.conf:

net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr

Do you know what the "default values" were before you set these?

On stock kernels this is what you'll find:

net.core.default_qdisc=pfifo_fast
net.ipv4.tcp_congestion_control=cubic

(edit: I meant Debian kernels - I don't know if other vendors tweak this on their stock kernels).

angstrom said: On your VPS at UltraVPS?

yup

Do you know what the "default values" were before you set these?

no idea - am running Debian 9.9 with 4.9.0-9-amd64 kernel

sysctl.conf was "stock" from the install before I made the changes

EDIT2:: as per @nullnothere above, might expect for stock Debian 9 kernel

net.core.default_qdisc=pfifo_fast
net.ipv4.tcp_congestion_control=cubic

@uptime said: Added to /etc/sysctl.conf

If you're up for some experimenting, I'm sure there are some additional tweaks you can test out for:

net.core.rmem_max
net.core.wmem_max

and also

net.ipv4.tcp_rmem
net.ipv4.tcp_wmem

YMMV.

Thanks - that might have boosted transfer rate by another 10%, can't say for sure but recent tests now show about 6.5 MB/s from UltraVPS Amsterdam to Psychz LA, Quadranet LA, and Quickpacket LA - and 9.5 MB/s to Colocrossing LA (hoping that will be consistent)

Played with using ProxyCommand to route scp through a few other locations - tunneling through BuyVM Las Vegas got me a hair over 7 MB/s to Letbox (Psychz LA) ... but for whatever reason no such joy tunneling through Colocrossing.

Anyway, good enough is good enough (and I'm mostly interested in the way to San Jose for this box).

@uptime said: Thanks - that might have boosted transfer rate by another 10%, can't say for sure

Of course the right way to test/verify these changes will be an iperf on both ends but for the casual/typical use case this is good enough I suppose. One has to draw the line somewhere and let the machines idle in peace rather than extract every drop of performance out of them. One has to be a kind employer of VPSs.

I am sorry, that's not possible. We only accept Paypal for the first invoice.

Waiting for LA offer too.

UltraVPS said: We only accept Paypal for the first invoice.

what other payment methods you support I thought it was only PayPal.

Milon

@UltraVPS said:

Thanks for your answer. I don't have paypal and I think there are some other people who don't have it. Think about us in the future, please. I understand that you want to eliminate risks of fraud. But maybe there are other ways to do this. As an example, you can give such customers access only to buy annual subscriptions without paypal. :-) Annual payment will be a demonstration of good intentions.

Ordered SAS-Special-1 and SAS-Special-2 with them, set up Debian 9, everything is working very smoothly so far. Pretty amazed. How long will the offers last?

@mtsbatalha said:
Please note that it's possible according their support upgrade the SAS-Special-1 for SAS-Special-2 plan in future.

Do you know if it applies even after the offer has ended?

I don't think so. But if you take your time it works.

twhstr said: @UltraVPS could I get 1 HDD please?

I am sorry, but that is not possible. But you can install your server manually and place / on /dev/vdb. We have just published an article for Debian 9 in our KB:

http://kb.ultravps.eu/kvm-cloud-server/installation/index.html#manual-installation-of-linux-distributions-general-guide

Other distributions (CentOS 7 and Ubuntu 18.04) will follow soon.

Do you get KVM nested virtualization, VMX pass through or whatever it is?

The link worked for me as posted but seems to have an issue if your browser tries to force https rather than http (certificate is from kb.providerdienste.de rather than kb.ultravps.eu)

Also might try http://kb.ultravps.eu/kvm-cloud-server/installation/debian9/index.html

Oh yea, tks for the heads up.
I use https everywhere (using the force https mode) on my browser. Just opened without the extension and it worked. Thank you!

Doesn't DEP means Data Execution Protection? Isn't it a security feature rather than one related to virtualization?

It's true. DEP is Data Execution Prevention and you'll need it for Hyper-V for example. More [here].(https://blogs.technet.microsoft.com/iftekhar/2010/08/09/enable-hardware-settings-in-bios-to-run-hyper-v/)

I have been using the lower-tier one for a while now, and I must say, this is almost the best experience I ever had with a KVM VPS. Updates are fast, everything "just works", not like how it is with those shit OpenVZ-s. Love it!

uxtvdl said: do you accep bitcoin and are these DMCA ignored ?

We accept Paypal only and do not tolerate any illegal activities.

doughnet said: These able to install windows?

Some customers of ours use Windows, but we don't support that officially. You might try if it works for you and request a refund otherwise.

heyzzx said: I like this promotion very much, can you add Los Angeles choice?

We would be happy to offer these deals in Los Angeles (or other locations), too. But unfortunately that's not possible.

The promotion will end soon. We have capacity for about 50 VMs left.
