Performance issue - Chart with 600 datapoints

Hi all,
I have sent my comments to the Apple Numbers team, still, perhaps someone has some idea here in the forums:
I have a table with approx. 600 datapoints in a two-column table:
Column A is the Date (e.g. 01.12.2005)
Column B is a price (e.g. 25.40)
Now "all I want" is a 2D or 3D Chart that I can easily adjust. Leaving every single date in from Column A results in a mess with the x-axis labels, all is entirely unreadable (no surprise there), so I have basically stripped all info except for the bi-yearly dates, i.e. I keep all prices in ColumnB for an accurate presentation of day-by-day values, but leave in Coloumn A only a few dates, such as
01.01.2005
01.06.2005
01.01.2006
01.06.2006
01.01.2007
01.06.2007
etc.
The resulting 3D Chart is still not useable due to the fact I can't move the x-axis labels further away. But even the 2D Chart is almost impossibly slow to re-fresh, and changes made in the inspector create a spinning beach ball for a good 10-20 seconds... whilst Activity Monitor shows one (of my 8!) cores are maxed out.
I am using his on a Mac Pro Early 2008 with 10 GB (yes, 10, not 1!) RAM, 8-core 2.8 GHz beauty, I could probably get the same performance on a 1-core machine :-/
ANY ideas on how to speed this up?! I am beginning to think I can draw this chart faster in Photoshop.

I have no experience of this kind of task in Photoshop
But you may be right.
At this time, Numbers is a very slow snail.

Performance issues ..with apex in reports version 3.1

Hello All,
I am using apex 3.1 oracle 10g.
I am facing with performance issues with apex . I am generating iteractive reports with apex and the number of records are huge - running in 30 to 40 thousands of records and the reports is taking almost 30 minutes.
How I can improve the performance of this kind of report. I am using apex collections.
How apex works in terms of retrieving the records -?
Please let me know .
Thanks/kumar

Performance issue working with OciArray

We have an performance issue with Oracle Spatial objects, e.g. SDO_GEOMETRY.
To get data from an Oracle Array (OciArray) there is functionality like:
OciNumberToRealArray
which is performing much better than doing
OciNumberToReal
for each instance.
But now we are sending an SDO_GEOMETRY to Oracle, so during the bind process we currently do:
for each number
do
OciNumberFromReal
OciCollAppend
enddo
We noticed that for the overall query, including getting the result, it is spending approx
6.3% in OciNumberFromReal
7.4% in OciCollAppend
On average we are sending 1500 values, so we are talking a lot of calls here.
Now since there is a way to get things from an array a lot faster using API's:
OCICollGetElemArray
OCINumberToRealArray
I am wondering why there is no way to set/put values into an array, like in:
OciNumberFromRealArray
or perhaps better
OciNumbersFromRealArray
I also noticed that there is no way of getting integer values from an array directly, you can only get one integer value at a time.
So there is no equivalent like:
OciNumberToIntArray
(there is OciNumberToInt and OciNumberFromInt)
Is no one experiencing this kind of stuff?
Regards,
Patrick

能提高多少性能？我怎么使用不成功，下面是部分代码，nOrdiCount是集合中元素总个数，m_pGeometry是一个GEOMETRY对象，执行OCICollGetElemArray之后，nOrdiCount的值被覆盖了。是oracle里面的代码把它覆盖了，我可以用这段代码去6个元素，超过6个元素，执行OCINumberToRealArray就无法返回了，不知何故？
OCINumber** pArray = new OCINumber*[nOrdiCount];
uword nCount = nOrdiCount;
memset(pArray, 0, sizeof(OCINumber*)*nOrdiCount);
OCICollGetElemArray(pConn->m_hOCIEnv, pConn->m_hOCIError, m_pGeometry->sdo_ordinates, 0, &exists, (void**)pArray, NULL, &nCount);
OCINumberToRealArray(pConn->m_hOCIError, (const OCINumber**)pArray, nCount, sizeof(real), pOrdiateData);
*OrdiateCount += nCount;
delete []pArray;
补充：
的确能够提高性能，但是其中有bug，OCICollGetElemArray函数中把我的函数中局部变量（栈变量）覆盖了，里面应该是内存访问越界了，期待改进！

Workflow Performance Issue (Used with OWB10.2.0.3)

Hi
We have a problem which seems consistent among our process flows.
The process flow contains a fork then runs 3 or 4 mappings routing back to an "AND" activity.
each mapping completes in a matter of seconds but the duration of the AND activity is consistently around 2mins.
This in terms of our overall load elapsed times adds an overhead of at least 20-30 mins which is not acceptable really.
Can anyone shed any light on what the AND is doing in the background and what can be done to speed it up e.g. what might need purging (everything i've seen tends to relate to use with Oracle Apps)?
Kind Regards
Mark

Insert performance issue with Partitioned Table.....

Hi All,

I'm concerned about the view in step 2 and the index join in step 3. A composite index with both columns might eliminate the index join and result in fewer read operations.
If you know which partition the data is going into beforehand you can save a little bit of processing by specifying the partition (which may not be a scalable long-term solution) in the insert - I'm not 100% sure you can do this on inserts but I know you can on selects.
The APPEND hint won't help the way you are using it - the VALUES clause in an insert makes it be ignored. Where it is effective and should help you is if you can do the insert in one query - insert into/select from. If you are using the loop to avoid filling up undo/rollback you can use a bulk collect to batch the selects and commit accordingly - but don't commit more often than you have to because more frequent commits slow transactions down.
I don't think there is a nologging hint :)
So, try something like
insert /*+ hints */ into ...
Select
     A.Ing_Acct_Nbr, currency_Symbol,
     Balance_Date,     Company_No,
     Substr(Account_No,1,8) Account_No,
     Substr(Account_No,9,1) Typ_Cd ,
     Substr(Account_No,10,1) Chk_Cd,
     Td_Balance,     Sd_Balance,
     Sysdate,     'Sisadmin'
From Ideaal_Cons.Tb_Account_Master_Base A,
     Ideaal_Staging.Tb_Sisadmin_Balance B
Where A.Vendor_Acct_Nbr = Substr(B.Account_No,1,8)
   And A.Vendor_Cd = b.company_no

Performance Issue with subtemplates

Hi,
I am working on subtemplates and my requirement needs a single main template which calls several localization specific subtemplates (A localization may have many subtemplates of its own, For example: US_subtemp1, US_subtemp2,US_subtemp3... similarly other localizations).
I would like to know is there any performance issue associated with the calls made to the subtemplates and on how this performance hit can be minimized.
Regards,
Arvind

Yes the data might be huge because Iam talking about thousands of payrolls that need to be shown in the report. So will a function call effect the performance is my question in this scenario, because even if don't have a function call we still have the same data, which remains huge. So, will the function call to the subtemplate lead to a performance hit when the data to be shown is large.
Lets take these two scenarios into account while approaching this issue:
~Single template and Huge data.
~One main template, many subtemplate calls and huge data.
So in these two scenarios will there be a difference in the performance due to the subtemplates call and if yes, then will it be considerable?
Regards,
Arvind

Lightroom 4 performance issues

Hello,
Months ago I switched from Aperture 3 to Lightroom 3 and quickly fell in love with the program.
I switched due to constant freezing and crashes in Aperture 3. I invested time and money to learn Lightroom 3. Performance in Lightroom 3 was superb. Anything I would do with regards to any type of adjustment gave instant results on the screen. Program never crashed or froze onec. Quite frankly, I was shocked in a very positive way.
This was on Macbook Pro i5, 8GB RAM, Hi Res Antiglare screen with Snow Leopard.
I purchased Lightroom 4. I did a clean install of OSX Lion and, clean install of LR4. New catalogs, no importing of anything. LR 4 is sooo slow. It works just like Aperture 3 worked, the precise reason that made me dump it.
The longer LR4 is opened, the slower it becomes. The more adjustments are applied, the slower it becomes. I will use brush and I have to wait to see results. I can't use brush. It takes me 15-30 min to brush small part of the image. I will slide adjustments and wait. I will click on crop tool and wait, wait, wait. I really love this program but I just can't work like that.
Would anyone share some light or advice on what could be done, on what is going on?
Thank you.

Rob,
I am working with NEF files and have done so in LR3. I understand from some reading that one of the benefits from converting files to DNG is that they are faster to work with. So I just copied one of my NEF as DNG and I have been working on it for about 15 minutes applying brush after brush and other adjustments to see if LR4 will slow down. Thus far it has been incredibly faster. I will continue to work on this one image and maybe convert few more to DNG to test but do you think that there might be some issue with NEF format? Another bizzare thing I just noticed is that when I open NEF image, my memory quickly goes up to over 3GB and that's not even during applying adjustments. Working now with DNG, memory is just around 1.3 GB. WHAT IS GOING ON HERE???
I wonder what type of files are other LR4 users that are reporing performance issues working with.
Please share your thoughts.
Thank you.

Apple refuses to replace it without me visiting a retail store (almost an hour drive).
Should I just take the hit and buy a new drive?

Personally, I would take it back, try a new one right in the store, and if that didn't work, I would demand my money back and wait until Apple fixes this hard drive issue. Oh, and tell the manager of the Apple Store you want an iTunes gift certificate for all your troubles and traveling time.

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Is there a recommended limit on the number of custom sections and the cells per table so that there are no performance issues with the UI?

Thanks Kelly,
The answers would be the following:
1200 cells per custom section (NEW COUNT), and up to 30 custom sections per spec.
Assuming all will be populated, and this would apply to all final material specs in the system which could be ~25% of all material specs.
The cells will be numeric, free text, drop downs, and some calculated numeric.
Are we reaching the limits for UI performance?
Thanks

Hi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

Performance issues with flashed 7800GT (G5)

Hey,
I recently flashed a PC 7800GT with the 128K OEM NVidia ROM. It's one of the cards with a physical 128K ROM chip, so no worries there. However, it doesn't deliver the performance I expected. I have a Late 2005 2.0 DC, 10GB DDR2 and use Leopard 10.5.8.
This is what OS X puts out (german):
NVIDIA GeForce 7800 GT:
Chipsatz-Modell:    GeForce 7800GT
Typ:    Monitor
Bus:    PCIe
Steckplatz:    SLOT-1
PCIe-Lane-Breite:    x16
VRAM (gesamt):    256 MB
Hersteller:    NVIDIA (0x10de)
Geräte-ID:    0x0092
Versions-ID:    0x00a1
ROM-Version:    2152.2
Performance issues are: I can't seem to reach frame rates that are anywhere near the results provided by barefeats. Quake 3 runs with approx 200fps in 1600x1200x32 (I expected 300+ fps), Quake 4 and UT2004 run okay, but not on high settings with high resolutions. So, not equivalent to what you wouldd expect from the system's specs) Same goes for Colin McRae Rallye. Now, I remember reading about performance issues in 10.5.8 with the flashed ROM since it doesn't seem to be a 1:1 copy of the original one. I didn't try it in Tiger since I don't exactly want to go back from Leopard. Am I right that this is probably an issue of the "OEM ROM" (from the macelite)? Does anyone have the real deal in terms of 7800GT ROMs and could provide me with a link?
Br

Hi-
If you send me an email via my website, I can send you a couple of ROMs that might work better.
http://www.jcsenterprises.com/Japamacs_Page/All_Things_PPC.html
Problem with the flashed 256 MB GT, though, is that Leopard runs slow.
Bad driver interaction.....
The 512 MB GTX is the way to go........

Performance Issues with 10.6.7 and External USB Drives

I've had a few performance issues come up with the latest 10.6.7 that seem to be related to external USB drives. I have a 2TB USB drive tha I have my iMovie content on this drive and after 10.6.7 update, iMovie is almost unusable. Finder even seems slow when browsing files on this drive as well. It seems like any access to the drive is delayed in all applications. Before the update, the performance was acceptable, but now it almost unusable. Most of the files on this drive are large dv files.
Anyone else experience this?

Performance issues with LOV bindings in 3-tier BC4J architecture

We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
The performance is OK (if not great) when the same code is running as 2-tier.
Does anyone have any good suggestions?

I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
of time to tune up our codes but that helped very little. Eventually, we found
the problem seemed to happen on TCP level. There is a 200ms delay in TCP
level. After we read some documents about Nagle Algorithm, we disabled a
registry key (TcpDelAckTicks) in windows2000 on both client and server. This
makes our program a lot faster.
Anyway, we think we should provide our clients a better solution other than
changing windows registry for them, for example, there may be a way to disable
that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
or anywhere in our codes. We have not figured out yet.
Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
See Also http://support.microsoft.com/default.aspx?kbid=328890
"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue.
