    At one of my servers at DigitalOcean I keep getting the message:
    Code (Text):
    Asynchronous AOF fsync is taking too long (disk is busy?). Writing the AOF buffer without waiting for fsync to complete, this may slow down Redis.


    That simply means the disks are too slow. Time for https://www.ovh.com

    I see some nice installation times on the Centmin install thread.

    serverhub also with Nvme... And Amsterdam(Builds bare metal on client specifications). Guess I need some time to figure out what's the best option. I run Centmin in a Cluster. So if one preforms bad, the rest suffers from it as well. Guess I gonna mix up some companies to get the best results.

    Nginx 1.27.x
    MariaDB 10.x/11.4+
    test underlying disk i/o performance to be sure

    But yes not all SSD disks are created equal as are not all NVMe SSD created equal. You can have a slow NVMe be slower than an SSD and vice versa as well as bad configuration/setup or bad hardware too.

    Had a look at netdata, some up and downs. Guess it's time to go somewhere else

    May I ask what application you are running? Since DO seems fine with 180-240 MB/s SSDs

    @Shirkit As they tell you at DigitalOcean "Happy Coding"..... And you will notice it. Even with the expensive RAID 10 as they tell.

    I had the same issue with AMAZON AWS due the fact their EBS block storage I/O is too slow. But that was in 2013/14 or so.
