  • VPS or RS

    Zitat von H6G

    What kind of performance are you looking for? Throughput or IOPS?

    IOPS, since on my RS2000 they are very sluggish even at around 30% cpu and mem usage. I suspect is all down to to many small read/writes to the disk.

  • VPS or RS

    I am looking to get another server. The disk performance is what is limiting me from using larger servers, since they run out of juice a lot faster then memory and disk on my RS2000. Since CPU and memory isn't my biggest concern I'm thinking maybe try VPS instead of RS. I'm thinking of RS1000 or VPS1000. I have tried looking through the benchmark page but it's not clear to me what kind of difference in perofrmance to expect? What is your experience?

  • Poor disk performance in the new servers in USA

    So to sum up the problem. I have 1 RS2000 G9.5 based in Germany and two RS2000 G11 based in US.

    All three servers have about the same performance when benchmarking with yabs.

    But in windows the US servers have considerably lower performance tested using two different benchmarks, not only visible in benchmarks but also noticeable when the servers are under load.

    All three servers use windows 2022 standard.

    One theory I have is it might be something with caching since the write speeds I get in windows is similar to what I get with linux and the read speeds are just insanely high compared to the linux tests. So I guess linux does not use caching. I have not changed any caching settings on either of the machines so it's still confusing.

    I can now see what you meant TBT and I'm sorry barked at you.

  • Poor disk performance in the new servers in USA

    I tested it using Atto Disk benchmark as well. Here you really see the difference. The operating system is a default Windows standard 2022.

    First image is the US server.

    I have a second US RS2000 G11 server with the same operatingsystem and the same performance difference in read/write.

    I also have a small vps 1000 G10 based in nurnberg de and it also has similar disk performance both read/write.

    This is not a problem only visible in benchmarks. I can clearly see how sluggish the US servers are compared to the DE.

  • Poor disk performance in the new servers in USA

    I had to mount the /dev/vdb3 disk instead and now it works. Now there is no longer any difference between read/write. I am not sure what conclusions I can actually draw from this.

    I also played through it again and you can get it to work like this:

    Now the tests run, but the disk tests only gives out 0:s.

  • Poor disk performance in the new servers in USA

    Thank you Andreas, I did that, but I get no confirmation it's running, has completed or anything. I went to All Yab Runs | VPSBenchmarks but I can't see anything from netcup there today. It's my understanding it will run the benchmark and upload the results to vpsbenchmarks? I then tried running curl -sL yabs.sh | bash to see if that changed anything but got the exactly same, nothing, prompt just goes to next level with no output.

  • Poor disk performance in the new servers in USA

    Thanks for all your answers guys! It was crystaldiskmark that gave me the numbers. I am not sure how they have calculated the MB but it looks like this:

    CrystalDiskMark test US server RS2000 G11

    And my older G9 RS2000 server gives me the highest numbers of 4000 both read/write.

    Anyone has any idea how to get yabs to run on windows? Virtualization is not enabled in bios and I'm not sure how to edit bios settings. I would think crystal diskmark shows my point anyway?

  • Poor disk performance in the new servers in USA

    Hello, I have 2 root servers in USA and several in Germany. I have noticed bad performance on the USA servers and it seems to be due to disk performance. Using a simple crystaldiskmark I can see that the write performance is quite bad on both the US servers. Around 500MB/s compared to Germany based servers that give similar write performance as read, somewhere around 4000MB/s. Is this is due to a problem, or is this the expected performance? If so I will have to move back the servers.
