I did some performance comparision between Dynamics 1.1 and Dynamics 2
directly after migrating the same repository - so the amount of
information is the same. As we are developing an OpenClient (Visual
Basic) dynamic graphical frond end driven by the Dynamics repository it
is essentual for us to retrieve information from the repository as fast
I used ry/app/rycsofetch.p in Dynamics 1.1 and fetchObject in
gshRepositoryManager in Dynamics 2 with the following code:
/* Code for Dynamics 1.1 */
DEFINE VARIABLE hHandleObjectCache AS HANDLE NO-UNDO.
DEFINE VARIABLE hTableObjectCache AS HANDLE NO-UNDO.
ETIME (YES) .
OUTPUT TABLE tt_object_instance,
OUTPUT TABLE tt_page,
OUTPUT TABLE tt_page_instance,
OUTPUT TABLE tt_link,
OUTPUT TABLE ttAttributeValue,
OUTPUT TABLE ttUiEvent).
MESSAGE ETIME .
/* Code for Dynamics 2 */
DEFINE VARIABLE hBufferCacheBuffer AS HANDLE NO-UNDO.
DEFINE VARIABLE hClassAttributeTable AS HANDLE NO-UNDO EXTENT 26.
RUN fetchObject IN gshRepositoryManager ("customerdw", /* object name */
22042, /* user object for admin
"", /* result code */
"", /* run attribute */
426, /* language english */
TRUE, /* entire container */
FALSE, /* design mode */
OUTPUT TABLE CACHE_object,
OUTPUT TABLE CACHE_objectpage,
OUTPUT TABLE CACHE_objectlink,
MESSAGE ETIME SKIP
VIEW-AS ALERT-BOX INFORMATION .
I ran both tests on the same machine (our development server in terminal
server mode, dual processor, up-to-date hardware). icfdb started with
the same parameters multi-user (-B 25000). Connection via self-service
client and ran the tests a couple of times the get good averages.
The container "customerdw" contains about 140 object instances
(toolbars, folder, sdos, viewer, browsers, fields in viewers etc.) and
should be considered as a small to medium sized object for out
The test results confuse me very much.
Dynamics 1.1 is very constant in retrievig the values: 3.5 seconds
Dynamics 2 needs 7 to 8 seconds for the first fetch in a session and 3.5
to 4 seconds for the following fetches in the same session.
We were hoping to get much better performance with version 2 but in fact
we receive a 10%-100% worse performance when reading the repository. To
have pretty good results in total we would expect less than a single
second (as this information needs to be transported to the client and
rendered there) .
Has anybody else ran test like these with object definitions similar
complex as described here? Is my benchmark code wrong? What else should
I do to speed test the system and retrieve the information needed to
render the screens.
