3230.0. "V1.2 SSB performance?" by ANDRIS::putnins () Mon Jun 22 1992 16:06

Re: 3.154 (repeated below) - This sounds terrific!  What kind of system
was used for the stress test (VMS/Ultrix, CPU, memory, local namespace/DECdns)?

Will a report be available; if so, when?

The kit has been packaged and sent to SSB, the formal nnouncement will
be forthcoming shortly.  We have to move the files onto the distribution
volumes and send out the announcement. Please have patiene we are
worn a bit thin here, but hope you will find that the wait was worth it.


Some quickie input on what we have seen with the new kit:

        open domain with 800+ child somainds: < 55 seconds
        > 90 notify commands active
        > 300 rules running
        > 100000 events processed in notif window
        > 2 dozen simultaneous graphs
        > 60 maps simultaneously displayed

        these were specific stress tests, we also did real world
        usability testing for longevity and performance; these
        tests are *STILL* running with memory consumption after
        a 4 days lower than the T1.2.4 startup requirements.

Keep the fath the memo is coming!!

Andy,

	The Stress testing for DECmcc V1.2 was done using a variety of systems
that we happen to have access to.  These includ DECstation 5000/125's,
VAXserver 3800's, VAXstation 3100 M38s', and a VAXstation 4000-60.

	Most of the systems had 32MEG of memory.  Testing was done using
both DNS and Local MIR.  Most tests were done both for VAX/VMS and MIPS/ULTRIX
systems.  Some tests used the LOCAL MIR, while others used DECDNS MIR, depending
on how the test machine was setup.

3230.2Which offered the best performance?CUJO::HILLDan Hill-Net.Mgt.-Customer ResidentFri Jun 26 1992 17:5812
    Bob, 
    	Can you provide some info on which system configuration was best
    and how closely each was in relation to the other (performance-wise)?
    
    	I'm also interested in how performance related to a DNS-based
    repository as opposed to a local MIR.  What was your DNS server
    platform?  How many objects in the namespace?  What were DNS$SERVER
    account resources configured (BYTLIM, ...)?  What was RMS buffer set to
    for each clearinghouse?
    
    -Thanks,
     Dan

    re -1
    
    I'm also interested in this info, so to put this note back in the unseen
    list I'm repeating the request.

3230.4Local MIR vs DNS performanceCUJO::HILLDan Hill-Net.Mgt.-Customer ResidentTue Aug 04 1992 01:5313
    I've forgotten which of the DECmcc engineers passed this info to me.
    (my apologies).
    
    500 nodes or less, Local MIR will perform better.
    Greater than 500 nodes to manage, DNS will perform better.
    
    My only comment is that I hope the X.500 product will perform better
    than DNS.  I've heard it is an order of magnitude faster than DNS. 
    That ain't much, but it's a start.
    
    By the way,  who is the X.500 representative for DECmcc?
