  • Poor disk performance on RS 16000 G12

    Zitat von Falzo

    Did the offer you bought specify any kind of IOps guarantue or did it just mention, that the underlying shared storage will consist of NVMe ?

    Are you just complaining about an artificial benchmark number or is in anyway affecting your workload?

    I would suggest to collect logs of high iowait impact on your real world use case, if you want to have something solid to base your complaints towards support on.

    Or maybe make use of the satisfaction guarantue and quickly back out before its too late and you are stuck with a product you don't like.

    I think the main point is being misunderstood here. The fio benchmark was not the reason to assume there is a problem. The problem was noticed first in real-world usage, and the benchmark was only used afterwards to investigate the possible cause.

    In my own experience, I have been running workloads on a weaker Het**zner VPS for more than a year without seeing this kind of storage-related degradation. I also had no issues with this Netcup server during the first week. The problem appeared only recently, which suggests something changed rather than simply being a case of unrealistic expectations about NVMe performance.

    The fio results, along with other system information and observations, were provided through multiple support tickets over several days after no response was received. The concern is not only the performance issue itself, but also the lack of communication and feedback from support.

    Even very small and less established providers usually acknowledge a support request within an hour or two. Waiting several days without even a basic response from a provider of this size is the frustrating part of this situation
