Connection between Servarica and liteserver
I recently purchased liteserver’s black Friday deal, and I discovered that the speed between the Servarica and liteserver is surprisingly slow, maximum 3M/s, but yabs speed seems normal now (wasn’t normal during the Black Friday.) I don’t know which side is the problem? @servarica_hani @LiteServer
is anyone using the two providers, how are the speed for you?
Thanks

How are you testing the speeds? iperf, file download, scp? etc
What do the traceroutes/MTRs look like inbound and outbound from both machines to the other?
LiteServer's hardware is premium but their network outside of Europe can be improved.
I had similar problem before, wget/scp from liteserver storage box to some destinations were as slow as ~2MB/s, while on liteserver nvme box it was constantly ~30MB/s. I assume this is a limitation on the liteserver side. Maybe load was too high during BF.
I test by scp
The traceroute seems fine:

Try running iperf3 between the two and see what kind of results you get.

Seems fine…? hmm
Sometimes I even got within KB/s.
If you experience performance issues, you should also have to perform several debug action to narrow down it's source.
If iperf show decent rates, it could be an IO/CPU issue on one or both end slowing things down.
Please not that SCP is one the slowest methods to transfer data (especially with small files). I highly recommend to consider using rsync instead, it's so so so much faster.
If you need further help debugging this, I would advise to open a ticket with us instead of using LET as "3rd party ticket system" :-)
For everyone being unhappy with international speeds in our network (like APAC region): On long haul distances with serious latency (like 200ms+), you'll see performance decrease when using a single "tcp stream". This is just how TCP/IP networking works unfortunately. The longer the physical route, the more impact this'll have on network throughput. Using different IP transit carriers might show performance differences, but in the end it'll be still the physical length of the route impacting the end results.
I need to clarify that I did open a ticket, #RSQ-605717, but because I wasn’t sure which side is the problem, maybe your end or Servarica end, so I decided to open a thread here, asking that if there’s a member May having the machines on the both sides and having same issue, after all your support is only controlling your side of things, you can’t control Servarica side issues if there was any. Correct me if I am wrong, if today only a single side issue involved maybe the ticket system would work better, but when third parties are involved, it’s better to have other opinions gets involved.
Thanks
Will try rsync instead of scp.
I'm having issues with ServaRICA. Have tested across to RackNerd (Los Angeles) and HostHatch (Singapore) and M1 (Singapore), I seem to think it is ServaRICA's uplink that is heavily congested. I'm getting maximum 1MB/s now as I am typing this.
However if I do a LA to SG, I can get 10MBps with ease.
I've just tested with iperf from Netherlands to Servarica, and got 700mbps from Servarica, and 950mbps to it (4 parallel streams in both cases). To be honest, in a few weeks I have been with Serverica, I've never seen bad networking there. It's close to advertised 1G over the Atlantic and at all times.
But, also make sure you do proper tuning of the network stack, increase TCP buffers, and use Google BBR TCP congestion algorithm (+ fq qdisc), which shines on these rather big 100ms+ latency connections, it really makes a difference.
Finally, if you're copying files over, then stop and think, is it really the network speed that you're testing? Or maybe the disk speed? Both providers offer HDD arrays, and at least in Servarica case (never tried Liteserver) it can be really slow. Slow like down to 3-4 MB/s at times. Then "full" 10MB/s on a nice day, which is still only 80 mbps, but has really nothing to do with network speed.
actually we dont have any congestion at all from our side
we are using less than 50% of our dedicated capacity
the issue could be in the path between us and those servers
you need MTR to see where the issue happen and then we can debug etc
iperf (and hence yabs) performance != real world performance.
I benchmarked Servarica / @servarica_hani quite some time ago but don't remember the details, it was quite decent though iirc. I benchmarked @LiteServer recently (a storage VPS) and found their connectivity to be really nice within Europe but less attractive to other continents (and, as a side note, everything else like e.g. processor/mem, disks, etc was just great).
Generally speaking speeds of 200+ Mb/s are quite normal in the LE segment. I also, to go to an extreme, have a @Hybula VPS which has insanely fast connectivity, but of course also has a higher price tag (although they seem to do quite attractive promos from time to time). But then those guys also run a (not at all small and growing, >> half a Tb/s) IX very near to major, fat backbones.
If you look for a compromise between speed and price that is considerably better than LE average but still within mere mortal people's reach wrt cost my advice would be to approach from the other end and first find well connected and known for decent speed DCs and then for a provider having a presence there.
I use both, @LiteServer for encoding and @servarica_hani for storage. so far no problem.
Both are top providers.
I have the same issue. I would like to use Servarica as storage for my VPS but Liteserver seems to have terrible connection to it. I tried to upload a 1 gig test file to a domain on Servarica and use wget on Liteserver to test connection speed but it has a though times breaking 1MB/s whereas my Hetzner VPS easily breaks 30 MB/s.
My other other VPS in the Netherlands from Web horizon seems to get 15-20MB/s. So it seems it is the Liteserver connection.
I found a usecase to keep ServaRICA. I'll keep it for now.
