April 2005 G5 Dual 2.3 Performance questions

According to the G5 specs, the April units sported not only dual processors but also a FSB of about 1.15 Ghz. Can anyone explain the rational behind limiting the board to the DDR400 series of memory modules? Does it have anything to do with any design features of the Motorola CPU (what is it by the way??) which could therefore only use RAM up to 400mhz?
Secondly, the memory slots are paired into 4 pairs. Is the no-brainer answer that one half of each pair serves one of the two processors?
Thirdly, even though these are 32bit cPU's, is it reasonable to expect this G5 to perform well under the next iterrations of Max OS-X or do you think the 64bit world will obsolete us overnight?
Thanks in advance for your seasoned wisdom,
Sam
G5 APRIL 2005 DUAL 2.3GHZ 4GB RAM Mac OS X (10.4.9)

G4s are all 32-bit CPUs, and all G5s are 64-bit.
You can read about the G5 (aka PowerPC 970) here.
The Apple Developer notes on the April 2005 G5 are here.
The current MacBook and MacBook Pro use the Intel Core2 Duo, which is a 64-bit chip. The original models used the Core Duo, which is 32-bit.
PowerBooks are all 32-bit, since they used the 32-bit G4.
Leopard will not require 64-bit CPUs to run. What it will do is be fully 64-bit compliant. In Tiger, you cannot have a 64-bit application with a GUI. In Leopard, you will.
If Leopard required a 64-bit CPU, the original MacBooks, MacBook Pros, and all Mac Minis wouldn't work with it. I would be pretty shocked if Apple dropped support for the G4 with Leopard. Support for the G3 may be dropped, though. We'll have to wait until it's released in October to know for sure, though.

G5 Dual 2.3 (Early April 2005) with Radeon 9650XT (256mb) Driver Question

My system is working fine. Out of curiosity I glanced at the ATI dowloads and saw that the 9650xt (Radeon) for Mac has a driver with a newer date than my computer. As a new Mac user I want to ask: do most of you leave it alone unless you have a problem? Thank you.
G5 Dual 2.3 (Early April 2005) with Radeon 9650XT (256mb) Mac OS X (10.4.9) Have never updated a driver on a Mac before.

ATI Support would not comment either so I will contact Apple Support.

Simple performance question

Simple performance question. the simplest way possible, assume
I have a int[][][][][] matrix, and a boolean add. The array is several dimensions long.
When add is true, I must add a constant value to each element in the array.
When add is false, I must subtract a constant value to each element in the array.
Assume this is very hot code, i.e. it is called very often. How expensive is the condition checking? I present the two scenarios.
private void process(){
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
         if (add)
         matrix[i][ii][iii][...] += constant;
         else
         matrix[i][ii][iii][...] -= constant;
private void process(){
if (add)
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
         matrix[i][ii][iii][...] += constant;
else
for (int i=0;i<dimension1;i++)
for (int ii=0;ii<dimension1;ii++)
for (int iii=0;iii<dimension1;iii++)
    for (int iiii=0;iiii<dimension1;iiii++)
       matrix[i][ii][iii][...] -= constant;
}Is the second scenario worth a significant performance boost? Without understanding how the compilers generates executable code, it seems that in the first case, n^d conditions are checked, whereas in the second, only 1. It is however, less elegant, but I am willing to do it for a significant improvement.

erjoalgo wrote:
I guess my real question is, will the compiler optimize the condition check out when it realizes the boolean value will not change through these iterations, and if it does not, is it worth doing that micro optimization?Almost certainly not; the main reason being that
matrix[i][ii][iii][...] +/-= constantis liable to take many times longer than the condition check, and you can't avoid it. That said, Mel's suggestion is probably the best.
but I will follow amickr advice and not worry about it.Good idea. Saves you getting flamed with all the quotes about premature optimization.

BPM performance question

Guys,
I do understand that ccPBM is very resource hungry but what I was wondering is this:
Once you use BPM, does an extra step decreases the performance significantly? Or does it just need slightly more resources?
More specifically we have quite complex mapping in 2 BPM steps. Combining them would make the mapping less clear but would it worth doing so from the performance point of view?
Your opinion is appreciated.
Thanks a lot,
Viktor Varga

Hi,
In SXMB_ADM you can set the time out higher for the sync processing.
Go to Integration Processing in SXMB_ADM and add parameter SA_COMM CHECK_FOR_ASYNC_RESPONSE_TIMEOUT to 120 (seconds). You can also increase the number of parallel processes if you have more waiting now. SA_COMM CHECK_FOR_MAX_SYNC_CALLS from 20 to XX. All depends on your hardware but this helped me from the standard 60 seconds to go to may be 70 in some cases.
Make sure that your calling system does not have a timeout below that you set in XI otherwise yours will go on and finish and your partner may end up sending it twice
when you go for BPM the whole workflow
has to come into action so for example
when your mapping last < 1 sec without bpm
if you do it in a BPM the transformation step
can last 2 seconds + one second mapping...
(that's just an example)
so the workflow gives you many design possibilities
(brigde, error handling) but it can
slow down the process and if you have
thousands of messages the preformance
can be much worse than having the same without BPM

Swing performance question: CPU-bound

Hi,
I've posted a Swing performance question to the java.net performance forum. Since it is a Swing performance question, I thought readers of this forum might also be interested.
Swing CPU-bound in sun.awt.windows.WToolkit.eventLoop
http://forums.java.net/jive/thread.jspa?threadID=1636&tstart=0
Thanks,

You obviously don't understand the results, and the first reply to your posting on java.net clearly explains what you missed.
The event queue is using Thread.wait to sleep until it gets some more events to dispatch. You have incorrectly diagnosed the sleep waiting as your performance bottleneck.

Xcontrol: performance question (again)

Hello,
I've got a little performance question regarding xcontrols. I observed rather high cpu-load when using xcontrols. To investigate it further, I built a minimal xcontrol (boolean type) which only writes the received boolean-value to a display-element in it's facade (see attached example). When I use this xcontrol in a test-vi and write to it with a rate of 1000 booleans / second, I get a cpu-load of about 10%. When I write directly to a boolean display element instead of the xcontrol,I have a load of 0 to 1 %. The funny thing is, when I emulate the xcontrol functionality with a subvi, a subpanel and a queue (see example), I only have 0 to 1% cpu-load, too.
Is there a way to reduce the cpu-load when using xcontrols?
If there isn't and if this is not a problem with my installation but a known issue, I think this would be a potential point for NI to fix in a future update of LV.
Regards,
soranito

Okay, I think I understand question now. You want to know why an equivalent xcontrol boolean consumes 10x more CPU resource than the LV base package boolean?
Okay, try opening the project I replied yesterday. I don't have access to LV at my desk so let's try this. Open up your xcontrol facade.vi. Notice how I separated up your data event into two events? Go the data change vi event, when looping back the action, set the isDataChanged (part of the data change cluster) to FALSE. While the data input (the one displayed on your facade.vi front panel), set that isDataChanged to TRUE. This is will limit the number of times facade will be looping. It will not drop your CPU down from 10% to 0% but it should drop a little, just enough to give you a short term solution. If that doesn't work, just play around with the loopback statement. I can't remember the exact method.
Yeah, I agree xcontrol shouldn't be overconsuming system resource. I think xcontrol is still in its primitive form and I'm not sure if NI is planning on investing more times to bug fix or even enhance it. Imo, I don't think xcontrol is quite ready for primetime yet. Just too many issues that need improvement.

PowerMac G5 1.8 GHz Dual (Buy April 2005) Graphics Cards?

I want to buy a new graphics card for my PowerMac 1.8 Dual GHz which a got in April of 2005. I have not made any improvments to the hardware at all. All I do know is that the Nvidia 6600 Upgrade on Apple.com will not fit into my computer slots. If someone can tell me out of this list, the ones that will fit into my computer. Thanks
One of the following graphics cards:
ATI Radeon X800 XT Mac Edition
ATI Radeon 9800 XT or 9800 Pro
NVIDIA GeForce 6800 Ultra DDL or 6800 GT DDL
NVIDIA GeForce 7800 GT
NVIDIA Quadro FX 4500
PowerMac G5 Dual 1.8GHz Mac OS X (10.4.3) I don't know if I have PCI or PCI-X or PCI-Express ports.

Happy New Year!!!
Would you say ATI Radeon 9800 Pro is better than Nvidia 6800, in terms of both performance and price?
Thanks in advance.

Functions slowing down performance question

Hey there.
I've got a query that really slogs. This query calls quite a few functions and there's no question that some of the work that needs to be done, simply takes time.
However, someone has adamantly told me that using functions slow down the query compared to the same code in the base SQL.
I find this hard to believe that the exact same code - whether well written or not - would be much faster in the base view than having a view call the functions.
Is this correct that functions kill performance?
Thanks for any advice.
Russ

There is the performance impact of context switching between SQL and PL/SQL engines. Pure SQL is always faster.
SQL> create or replace function f (n number) return number as
2 begin
3 return n + 1;
4 end;
5 /
Function created.
SQL> set timing on
SQL> select sum(f(level)) from dual
2 connect by level <= 1000000;
SUM(F(LEVEL))
5.0000E+11
Elapsed: 00:00:07.06
SQL> select sum(level + 1) from dual
2 connect by level <= 1000000;

Performance question when compare date with date or char with char

Hello from Germany (Frankfurt) !
I am working on Oracle 9.2.0.8.0
and have to solve following problem:
Comparison of a date and char fields.
Now two ways to do it.
Either I compare char with char and convert date to char,
or I compare date with date and convert char to date.
Now the performace question. Which operation takes more effort for the database?
So why not to try and to see the results?
First create table:
CREATE TABLE TEST (
char_date VARCHAR2(8),
real_date DATE
NOLOGGING;
Then insert 1.000.000 rows
BEGIN
for x in 1..1000000
loop
insert into test (char_date, real_date) VALUES('19990101', TO_DATE('2006.01.01', 'YYYY.MM.DD'));
end loop;
COMMIT;
END;
Collect statistics
EXEC dbms_stats.gather_table_stats('TESTER', 'TEST');
Now run some selects for date to char conversion:
Elapsed: 00:00:00.00
SQL> select * from test t where TO_DATE(char_date, 'YYYYMMDD') > real_date;
no rows selected
Elapsed: 00:00:03.02
SQL> select * from test t where TO_DATE(char_date, 'YYYYMMDD') > real_date;
no rows selected
And some selects for char to date conversion:
Elapsed: 00:00:03.02
SQL> select * from test t where char_date > TO_CHAR(real_date, 'YYYYMMDD');
no rows selected
Elapsed: 00:00:02.05
SQL> select * from test t where char_date > TO_CHAR(real_date, 'YYYYMMDD');
no rows selected
Elapsed: 00:00:02.05
SQL>
As you see when I compare char with char and convert date to char it seems to be faster (almost 1 second)
Is the test correct?
I still not sure, what gets better performance...
Any idea?
Thanks!

Depends on whether you want the right results or not.
Why don't you run the following two queries and see if the difference in results tells you anything?:
with t as (select to_date('01/02/2007', 'dd/mm/yyyy') date_col from dual
           union all
           select to_date('02/02/2007', 'dd/mm/yyyy') from dual
           union all
           select to_date('03/02/2007', 'dd/mm/yyyy') from dual
           union all
           select to_date('03/03/2006', 'dd/mm/yyyy') from dual)
select *
from   t
where date_col < to_date('04/03/2006', 'dd/mm/yyyy');
with t as (select to_date('01/02/2007', 'dd/mm/yyyy') date_col from dual
           union all
           select to_date('02/02/2007', 'dd/mm/yyyy') from dual
           union all
           select to_date('03/02/2007', 'dd/mm/yyyy') from dual
           union all
           select to_date('03/03/2006', 'dd/mm/yyyy') from dual)
select *
from   t
where to_char(date_col) < '04/03/2006';

Performance Question:Two 2.8GHz Quad-Core VS Two 3.0GHz Quad-Core?

I am in the market for a Mac Pro and I want to know if there is a huge performance difference between the dual 2.8 quad-cores and the dual 3.0 quad-cores. I do video editing, web sites and graphic design, as well as gaming. Is 200 more mhz really worth $800? Please let me know what is a better investment?

Hello,
Your question is one seen often here.
I would agree that the difference in time-to-completion for projects such as video editing is important. But one has to think in terms of seconds saved - per project. In other words, if one saves "10 seconds" per project using the higher speed processors, does that represent a significant savings at the end of a year's worth of projects? That of course depends on how many "extra" projects get completed (and paid for). Most individual Mac users agree that it's not that significant a difference when it comes to profits gained vs extra cost of the machine.
Granting: If one is talking about a company with 500 people running high end rendering projects, the cumulative difference is significant because there'll be that many more "extra projects" completed over a given period. It's just obvious: increasing productivity on that scale is significant.
Video gaming is in an entirely different category: "personal preference." I think it's fine if a gamer finds the "mightier" machine provides a better experience. But it won't help you "win" a single video game. As one who was active in the Muscle Car Era of the 1960s, I think that was much like what we're seeing with video gamers today. If having a 450 hp muscle car was itself a status symbol, it still only meant that, sometimes, a street drag race could be won by "a bumper length" over a 400 hp car. No one can say they have the "right" to decide how you spend your money - it's up to you if the prestige is worth it to you.
Basically, given the above, I have to agree with Rick (and many others) on this question.

MBP with 27" Display performance question

I'm looking for advice regarding improving the performance, if possible, of my Macbook Pro and new 27'' Apple display combination. I'm using a 13" Macbook Pro 2.53Ghz with 4GB RAM, NVIDIA GeForce 9400M graphics card and I have 114GB of the 250GB of HD space available. What I'm really wondering is is this enough spec to run the 27" display easily. Apple says it is… and it does work, but I suspect that I'm working at the limit of what my MCB is capable of. My main applications are Photoshop CS5 with Camera RAW and Bridge. Everything works but I sometimes get lock ups and things are basically a bit jerky. Is the bottle neck my 2.53Ghz processor or the graphics card? I have experimented with the Open GL settings in Photoshop and tried closing all unused applications. Does anyone have any suggestions for tuning things and is there a feasible upgrade for the graphics card if such a thing would make a difference? I have recently started working with 21mb RAW files which I realise isn't helping. Any thoughts would be appreciated.
Matt.

I just added a gorgeous LCD 24" to my MBP setup (the G5 is not Happy) The answer to your question is yes. Just go into Display Preferences and drag the menu bar over to the the 24 this will make the 24 the Primary Display and the MBP the secondary when connected.

Performance question about 11.1.2 forms at runtime

hi all,
Currently we are investigating a forms/reports migration from 10 to 11.
Initialy we were using v. 11.1.1.4 as the baseline for the migration. Now we are looking at 11.1.2.
We have the impression that the performance has decreased significantly between these two releases.
To give an example:
A wizard screen contains an image alongside a number of items to enter details. In 11.1.1.4 this screen shows up immediately. In 11.1.2 you see the image rolling out on the canvas whilst the properties of the items seem to be set during this event.
I saw that a number of features were added to be able to tune performance which ... need processing too.
I get the impression that a big number of events are communicating over the network during the 'built' of the client side view of the screen. If I recall well during the migration of 6 to 9, events were bundled to be transmitted over the network so that delays couldn't come from network roundtrips. I have the impression that this has been reversed and things are communicated between the client and server when they arrive and are not bundled.
My questions are:
- is anyone out there experiencing the same kind of behaviour?
- if so, is there some kind of property(ies) that exist to control the behaviour and improve performance?
- are there properties for performance monitoring that are set but which cause the slowness as a kind of sideeffect and maybe can be unset.
Your feedback will be dearly appreciated,
Greetigns,
Jan.

The profile can't be changed although I suspect if there was an issue then banding the line would be something they could utilise if you were happy to do so.
It's all theoretical right now until you get the service installed. Don't forget there's over 600000 customers now on FTTC and only a very small percentage of them have faults. It might seem like lots looking on this forum but that's only because forums are where people tend to come to complain.

Dual monitor, and other questions....

I'm sorry for these questions if they've already been discussed... with all the back lash, I'm having a hard time wading through all the comments.
I have a macbookpro.
I use an external 24" monitor along with my 15" laptop for editing. My 15" is used for my canvas.
1: Can I use this set up with the new FCP X?
I use PPro CS5 currently and I like the way it handles media and saving my projects.
2: How does FCP X handle media?
2.a: Does it handle media like iPhoto / Aperture?
2.b: Are projects saved like in iMovie?
I keep all my media on external hard drives.
3: Will this be a problem with FCP X?
Thank you in advance for your help.
Tony

On my dual monitor Mac pro, the main monitor has the timeline and canvas. The second monitor has the events I think, basically the bin. You'd probably want to make your 24 the main monitor
FCP X handles media and projects a lot like iMovie. iTunes and iPhoto are accessed just like iMovie. You can save media to whatever drive you want although you can't really drill down to a particular location
Hope this helps

Performance question on small XML content but with large volume

Hi all,
I am new to Berkeley XML DB.
I have the following simple XML content:
<s:scxml xmlns:s="http://www.w3.org/2005/07/scxml">
<s:state id="a"/>
<s:state id="b"/>
<s:state id="c"/>
</s:scxml>
about 1.5K bytes each but the total number of such content is large (5 million+ records).
This is a typical query:
query 'count(collection("test.dbxml")/s:scxml/s:state[@id="a"]/following-sibling::s:state[@id="e"])'
where the id attribute is used heavily.
I've tested with about 10000 records with the following indexes:
Index: edge-attribute-equality-string for node {}:id
Index: unique-node-metadata-equality-string for node {http://www.sleepycat.com/2002/dbxml}:name
Index: edge-element-presence-none for node {}:scxml
Index: edge-element-presence-none for node {}:state
but the query took just under one minute to complete. Is this the expected performance? It seems slow. Is there anyway to speed it up?
In addition, the total size of the XML content is about 12M but ~100M of data is generated with the log.xxxxxxxxxx files. Is this expected?
Thanks.

The indexes are used in this case and the execution time was reduced to about 40 seconds. I set the namespace with setNamespace when the session is created. Is this the reason why the indexes without URI are used?
Any other performance improvement hints?
Thanks,

Performance questions in Oracle Forms/Reports of Application Server 10g

Hello.
I have a dual Xeon 2.6 computer with 3 GB of memory and 6 GB of cache, running RedHat EL 3 with Oracle AS 10g (9.0.4.0.0).
Application Server is used to run some applications created with forms, and it generates several reports, but the forms are also used as a front end to another Oracle Database (Oracle 7.0, runing in Sun Solaris 5.6).
I've notested (and also my users) the application is getting very slow (is running in a dual Xeon, with 2 Gbit nics, in a 3 Gb backbone).
The speed (or lack of it) is most noted when the forms are generating the reports (it used to be fast - 2 seconds) and now it can take up to 5 minutes.
The AS 10g, when generating the reports, almost all of the querys go to the other server (in Solaris) and the results return to the server, and then the report is generated. The network has no problems (at least, that i know of), and the network performance is not an issue - both the servers are connected to a Gbit switch.
Can someone may have an ideia of it can be?
even in the clients, when running the forms application, the transition of the several menus is slow, and it used to be more fast.
the 10g is using Java Jinitiator 1.3.18. Can it be from that ? i'm not certain, but i could say this things start happen when we upgraded the jinitiator from 1.3.13 to 1.3.18...
My users are really getting on my nervers and i cant do nothing, because they have reason...
any help would be appreciated !
Cheers
Bruno Santos

Bruno, did you solve the performance problem? I'm experiencing the same lack of speed.
