Hi all,

I am new to Dec unix, i need to know if the kernel parameters as below have
anything obviously wrong in them.:

ipc:
        msg-mnb = 32768
        sem-mni = 1536
        msg-mni = 768
        msg-tql=512
        shm-max = 2147483647
        shm-mni = 2048
        num-of-sems = 512
        shm-seg = 512
        sem-ume = 400
        sem-opm = 400
        sem-msl = 1600
        ssm-threshold = 0

        max-kernel-ports=93911
        port-hash-max-num=4695550
        port-reserved-max-num=24837
proc:
        open-max-soft = 4096
        open-max-hard = 4096
        max-proc-per-user = 512

        max-threads-per-user=512
        per-proc-stack-size=4294967296
        max-per-proc-data-size=4398046511104
        maxusers=1024
        task-max=8213
        thread-max=16424
        num-wait-queues=1024
        num-timeout-hash-queues=1024
        max-per-proc-address-space=4398046511104
        per-proc-address-space=4398046511104
        max-per-proc-stack-size=4294967296
        per-proc-data-size=4398046511104
psdc:
        Subsystem_Description = psdc device driver
        Module_Type = Dynamic
        Module_Path = /subsys/psdc.mod
        Module_Config_Name = psdc
        Device_Dir = /dev
        Device_Char_Major = any
        Device_Char_Minor = 0
        Device_Char_Files = psdc
        Device_User = root
        Device_Group = 0

vfs:
        bufcache = 3
        max-vnodes = 16000
        min-free-vnodes = 3500
        fifo-do-adaptive = 0

        name-cache-size=22853
        nvnode=10388
vm:
        ubc-maxpercent = 10

        vm-max-rdpgio-kluster=16384
        vm-maxvas=4398046511104
        ubc-minpercent=5
        ubc-borrowpercent=8
        vm-ubcseqstartpercent=7
        gh-fail-if-no-mem=0
pts:
        nptys = 1024

net:
        netisrthreads=4


rt:
        aio-max-num=4096
        aio-task-max-num=2048
        aio-max-percent=5
        aio-max-retry=20
        aio-retry-scale=5
        sigqueue-max-num=128

generic:
        insecure-bind=1


Pls let me know if any parameter in above can hamper system performance in
anyway.

Thanks in advance i shall summarize
