2558.0. "Very different response time on SHOW ALL REFERENCE" by BYBLOS::TAMER () Thu Mar 12 1992 16:26

I am surprised at the behavior of the REGIS FM on SHOW entity ALL REFERENCE
attributes. I have two global entities that are registered. 
The first entity (qms_cd) takes from 4-6 seconds to display its reference 
attributes.
The second (qms_database) takes repeatdly between 39-49 seconds to show its 
reference attributes. 
This behavior does not change much if we try it on a local nameserver.

The difference between the two entities is that qms_cd has one child entity.
The other qms_database has about 25 child and granchild entities. However, all
children are dynamic and never registered. I would think that this should have 
nothing to do with show <entity> all reference.

I tried defining mcc_registration_fm_log to 6. What I can see is that after
building each DICT ENTITY specs, for the qms_database (slow) entity, there is a
pause of a few seconds for each attribute, EVERY TIME. While for the qms_cd 
(fast) entity, there is no pause after each DICT ENTITY dump.

Here is a screen cut of the DICT ENTITY after which the pause is happening:

 DICT ENTITY:
        entity [0] wild = NOT_WILD class = 1 id = 0 type = 35
        instance = .:..
        %X9A3A0000
        entity [1] wild = NOT_WILD class = 5 id = 0 type = 35
        instance = g...
        %X67000000
        entity [2] wild = NOT_WILD class = 3 id = 0 type = 3
        instance = VALUE_DATA_TYPE


below is the small script and the output that show the time difference:

$man/ent
SPAWN SHOW TIME
SHOW QMS_CD .QMS.ECRU all REFER

SHOW QMS_DATABASE .QMS.DB all REFER

exit

output:

What bothersome about this is that everytime we do :
	SHOW QMS_DATABASE .qms.db all attributes

we have this awfully long pause for the references attributes

Any ideas ?

2558.1Normalize for the test please...TOOK::R_SPENCENets don&#039;t fail me now...Mon Mar 16 1992 17:3610
    Try this. Add a second pair of tests after the first pair.
    
    The first time you access an instance of a global entity is when the
    code is loaded into memory and various memory tables and stacks
    updated and created. So, in order to make the test fair you should
    have all the needed code loaded before doing timing tests as I would
    expect that most usage of the product is after having it up for a
    while, not just run it and do a single command.

2558.2Here is a normalized testECRU::TAMERMon Mar 16 1992 20:10117
Here are four tries for each entity. As you can see, no noticeable effect.
