Hi,

If direct IO is disabled, the startup speed will be doubled, including some other tests. I find that direct IO has a great impact on the read performance.

    Hi Evgenii,

    The storage used is not SSD.

    We will use different versions of ignite for further testing, such
    as ignite2.8.
    Ignite is configured as follows:

    Hi,

    Can you share full logs and configuration? What disk so you use?

        Among them:
        CO_CO_NEW: ~ 48 minutes(partitioned,backup=1,33M)

        Ignite sys cache: ~ 27 minutes

        PLM_ITEM:~3 minutes(repicated,1.9K)

        Hi community,

        We have 5 servers, 16 cores, 256g memory, and 200g off-heap
        memory.
        We have 7 tables to test, and the data volume is
        respectively:31.8M,495.2M,552.3M,33M,873.3K,28M,1.9K(replicated),others
        are partitioned(backup = 1)

        VM args:-server -Xms20g -Xmx20g -XX:+AlwaysPreTouch
        -XX:+UseG1GC -XX:+ScavengeBeforeFullGC
        -XX:+DisableExplicitGC -XX:+PrintGCDetails
        -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps
        -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10
        -XX:GCLogFileSize=100M -Xloggc:/data/gc/logs/gclog.txt
        -Djava.net.preferIPv4Stack=true -XX:MaxDirectMemorySize=256M
        -XX:+PrintAdaptiveSizePolicy

        Today, one of the servers was restarted(kill and then start
        ignite.sh) for some reason, but the node took 1.5 hours to
        start, which was much longer than expected.

        After analyzing the log, the following information is found:

        Binary recovery performed in 4970233ms.

        Among them, binary recovery took 4970 seconds.

        Our question is:

        1.Why is the start time so long?

        2.Is the current state of ignite, with the growth of single
        node data volume, the restart time will be longer and longer?

        3.Do have any suggestions for optimizing the restart time?
