Response times for apple displays
Hi,
am in the market for a 20-22" LCD monitor for our G4 machine. Sometime we'll upgrade the machine to a faster intel-mac. I have been hunting around for good deals on LCD's and while most other vendors seem to list their response times, I did not see them for the Apple displays. Any notes on where to find them?
Also am looking at Dell and their response times seem quite slow (15-16 ms) for the 2007WFP or just the FP displays. While Samsung and a host of others are typically below 8ms. I do understand there are "tricky" ways of measuring these number, but 15-16ms seems pretty slow to me, and since my teen agers play a lot of games on the machine, seems like I should go for faster #'s.
That said, any recommendations on other brands? Apple's are very pricey, but nice looking too.
thx
'mark
m_ahienius,
14 ms.
See http://www.apple.com/displays/specs.html
If you can afford a 23-inch display, go for it. I have owned both the 20-inch Apple LCD and the 23-inch. Bigger is better.
The real question is "why do you care about response time?". It is only meaningful for watching movies and playing games. Not for "ordinary" work.

SLR - transaction response time for all appl. servers together
Hi,
we want to have in SLR response time for defined transaction. We have activated necessary steps for monitoring transactions, started CPH and we can see in SLR average response times.
We have several application servers and we want to have in SLR TOTAL response time for all appl. servers together.
Is it possible? What is necessary steps to do it?
Thanks for all hints.
Regards,
RomanHi Andreas,
Another way to approach this would be to use CCMS transaction monitoring by maintaining table ALTRAMONI (in the satellite system) as described here: http://help.sap.com/saphelp_nw70/helpdata/en/b3/468e3b093d4031e10000000a11402f/content.htm
In RZ20 you'll be able to see the last 24 hours of performance data in a 1-hour granularity, as well as the last 30 minutes in a higher granularity. Depending on your requirements you can then configure alerting so that you get an email when performance passes a certain threshold.

Significant difference in response times for same query running on Windows client vs database server
I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)|
| 0 | SELECT STATEMENT | | 2852K| 46M| | 69851 (1)|
| 1 | HASH UNIQUE | | 2852K| 46M| 153M| 69851 (1)|
|* 2 | TABLE ACCESS FULL| DOCUMENTS | 2852K| 46M| | 54063 (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using. -
Response time for Error Messages - Please Help
Hi
I have a PRO C application talking to an Oracle database.
The Response time for successful query is within desirable limits.
But when there is a error condition (eg SQLError -3113,or connection refused) it takes more than 9 minutes for the database to respond with the error code.
This condition is observed with only one database while the others are working fine.
What is the reason for this? Can’t it be reduced?
Regards
Davidever been faced with the same problem ?
Why deleting ? It that only one way to fix this problem ?
What are the others doing in such cases. Or am I the only one person
where has this special problem on the world. Becides I dont believe
in solving the problem through removing mentioned directory and
reinstalling. Nevertheless I will try it. I let you know about the result.

Strange response time for an RFC call viewed from STAD on R/3 4.7
Hello,
On our R/3 4.7 production system, we have a lot of external RFC calls to execute an abap module function. There are 70 000 of these calls per day.
The mean response time for this RFC call is 35 ms.
Some times a few of them (maybe 10 to 20 per day) are way much longer.
I am currently analysing with STAD one of these long calls which lasted 10 seconds !
Here is the info from STAD
Response time : 10 683 ms
Total time in workprocess : 10 683 ms
CPU time : 0 ms
RFC+CPIC time : 0 ms
Wait for work process 0 ms
Processing time 10.679 ms
Load time 1 ms
Generating time 0 ms
Roll (in) time 0 ms
Database request time 3 ms
Enqueue time 0 ms
Number Roll ins 0
Roll outs 0
Enqueues 0
Load time Program 1 ms
Screen 0 ms
CUA interf. 0 ms
Roll time Out 0 ms
In 0 ms
Wait 0 ms
Frontend No.roundtrips 0
GUI time 0 ms
Net time 0 ms
There is nearly no abap processing in the function module.
I really don't uderstand what is this 10 679 ms processing time especially with 0 ms cpu time and 0 ms wait time.
A usual fast RFC call gives this data
23 ms response time
16 ms cpu time
14 ms processing time
1 ms load time
8 ms Database request time
Does anybody have an idea of what is the system doing during the 10 seconds processing time ?
Regards,
OlivierHi Graham,
Thank you for your input and thoughts.
I will have to investigate on RZ23N and RZ21 because I'm not used to use them.
I'm used to investigate performance problems with ST03 and STAD.
My system is R/3 4.7 WAS 6.20. ABAP and BASIS 43
Kernel 6.40 patch level 109
We know these are old patch levels but we are not allowed to stop this system for upgrade "if it's not broken" as it is used 7/7 24/24.
I'm nearlly sure that the problem is not an RFC issue because I've found other slow dialog steps for web service calls and even for a SAPSYS technical dialog step of type <no buffer>. (what is this ?)
This SAPSYS dialog step has the following data :
User : SAPSYS
Task type : B
Program : <no buffer>
CPU time 0 ms
RFC+CPIC time 0 ms
Total time in workprocs 5.490 ms
Response time 5.490 ms
Wait for work process 0 ms
Processing time 5.489 ms
Load time 0 ms
Generating time 0 ms
Roll (in+wait) time 0 ms
Database request time 1 ms ( 3 Database requests)
Enqueue time 0 ms
All hundreds of other SAPSYS <no buffer> steps have a less than 5 ms response time.
It looks like the system was frozen during 5 seconds...
Here are some extracts from STAD of another case from last saturday.

ISA Server 2006 + Average response time for Non Cached requests = performance issues?!?!?!
All,
I am in a predicament with internet browsing speeds...We have a 3rd party look after our line and internet facing f/w so I cant troubleshoot them, so at the moment Im looking at ISA as the potential bottleneck - we have a fairly standard environment:
Internal > Local Host > Perimiter n/work > Firewall > Internet
I have been running custom reports on the ISA server to see what data can be collected - I have noticed that "Average response time for non cached requests" (traffic by time of day) can be as high as 76 seconds!!!!!! Cached hits are between .5
and 2 seconds.
I have also coonfigured a connectivity verifier which is also flagging slow connectivity, massively over the >5000ms and also reporting "cant resolve server name on occassions- and this is configured for
www.Microsoft.com --- DNS ???!?!, however I have looked through DNS (no obvious errors / config issues) which I can see
I have run the BPA on ISA server to ensure its Health - - connectivity verifier errors flagged timeouts to microsoft.com as expected...
Can anyone advise any obvious areas to investigate as Im struggling! - as always the 3rd party have told us the internet pipe is fine :OProblem resolved.
DNS forwarders have been changed on the ISA server / DNS and this has improved lookup speed considerably.
thanks all :) -

On our R/3 ECC6 production system ,we have one aRFC call by external system,there are 200000 times per day.
and the response time for the RFC call is 35ms ,Some times its response time(commit time) are much longer and up to 2 seconds.
There is very simple code for the RFC as shown below
insert ztable from table lt_internal_table.
commit work
call function 'function_name'
starting new task 'N'.
tables
it_tab = lt_internal_table.
Regards,
ShiChunQingDear Randorlf ,
Now i can determine that statement "commit work" have a high cost some times.
I write a simple report as show below,
One high cost will occurs per several minutes.
report ztest.
do 10 times.
GET RUN TIME FIELD t1.
INSERT ytest_table FROM TABLE lt_tab.
GET RUN TIME FIELD t2.
t1 = t2 - t1.
WRITE:/ 'insert:',t1,sy-uzeit.
COMMIT WORK.
GET RUN TIME FIELD t3.
t2 = t3 - t2.
WRITE: 'commit:',t2,sy-uzeit.
enddo.
Run results:
insert: 879 16:23:02 commit: 1,713 16:23:02
insert: 1,607 16:23:05 commit: 4,434 16:23:05

How to find the Response time for a particular Transaction
Hello Experts,
Am implementing a BAdI to achieve some customer enhancement for XD01 Transaction . I need to confirm to customer that after the implementation and before implementation what is the response time of the system
Response time BEFORE BAdI Implementation
Response time AFTER BAdI Implementation
Where can i get this.
Help me in this regard
Best Regards
SRiNiHello,
Within STAD, enter the time range that the user was executing the transaction within as well as the user name. The time field indicates the time when the transaction would have ended. STAD adds some extra time on using your time interval. Depending on how long the transaction ran, you can set the length you want it to display. This means that if it is set to 10, STAD will display statistical records from transactions that ended within that 10 minute period.
The selection screen also gives you a few options for display mode.
- Show all statistic records, sorted by star
This shows you all of the transaction steps, but they are not grouped in any way.
-Show all records, grouped by business transaction
This shows the transaction steps grouped by transaction ID (shown in the record as Trans. ID). The times are not cumulative. They are the times for each individual step.
-Show Business Transaction Tots
This shows the transaction steps grouped by transaction ID. However, instead of just listing them you can drill from the top level down. The top level will show you the overall response time, and as you drill down, you can get to the overall response time.
Note that you also need to add the user into the selection criteria. Everything else you can leave alone in this case.
Once you have the records displayed, you can double click them to get a detailed record. This will show you the following:
- Breakdown of response time (wait for work process, processing time, load time, generating time, roll time, DB time, enqueue time). This makes STAD a great place to start for performance analysis as you will then know whether you will need to look at SQL, processing, or any other component of response time first.
- Stats on the data selected within the execution
- Memory utilization of the transaction
- RFCs executed (including the calling time and remote execution time - very useful with performance analysis of interfaces)
- Much more.
As this chain of comments has previously indicated, you are best off using STAD if you want an accurate indication of response time. The ST12 (combines SE30 ABAP trace and ST05 SQL trace) trace times are less accurate that the values you get from ST12. I am not discounting the value of ST12 by any means. This is a very powerful tool to help you tune your transactions.
I hope this information is helpful!
Kind regards,

What %of Avg Response time for Avg DB Time is known as Good Perfformance ?
If my average response 875 mili seconds - what %of DB Time is accepted as best perofrmance.
could any one give bench marks for Best peforming ABAP (R/3) System>
Rgds
PRHey,
In general, normal performance should have
60% DB and 40% appl, however, those performance are right for ECC/R3, if you are using other system, this is not relevant, for example XI, might have 80%DB and only 20% appl.
it looks like your system is not having performance problems,
due to the fact that you have 875 mili sec average response time. -
Response time low to display 2700 records
In my program , i have tried to display 2700 records from Database using JSP.
But the response time is very slow. How do i overcome this problem.
My architecture is
JSP - EJB - HelperClass - DB.Find out where the performance bottleneck is
1) Database -> use PreparedStatements,
reuse an open database connection
2) JSP -> Check your string handling, use StringBuffer() for appending
lots of strings together
3) Network response -> Maybe try defining a static IP address for your
server

Urgent:How to Speed Up the Response time for PDF Report of 500 pages
hi all
i am running the 9ias on Solaris and Generating some reports
Which fetches around 50,000 records and Display them in pdf format.
When i am ruuning the Query at Database level Response time is Very fast.
But when i Run the Report in Web Browser same report takes 7-8 minutes.
So it seems that the Conversion to pdf and Displaying it takes most of time.
Does any one has idea What parameter's needs to be changed/Caching ??? /
or any other ways or methods which can be used to Reduce the Response time.
(its once a monthly Report and User need to Download all the 500 pages as
a Single Document).
Any help / suggestion please
thanks
jaiYou aren't by any chance calling a function in your repeating frame that in turn goes back and queries the database, are you? If so ... don't. We regularly do 500+ page PDF-file reports, and one thing we discovered early on was that repeatedly going back to the database while generating the report output (in our case, in calculations that were being done on each line of a report) slowed the output down by an order of magnitude. Instead, we now retrieve all the data needed for each report up front (via functions or views called in the initial SQL for the report), and just use Reports to format the output. MUUUUUUUCH faster -- 200 page reports that used to take 15 minutes to complete now complete in just seconds.
One way you can visually see if this is part of your problem is to watch the report execute in the Report Queue Manager application. If it spends all its time on the "Opening" stage then breezes through each page, this is not your problem. If instead it seems to take a long time generating each page, I'd suspect that this may be at least part of your delay.
