Slow PC Performance

Anyone else notice that after installing iTunes 8 Windows really slows down? I even noticed this with iTunes 7 (series) that my Windows Vista was incredibly slow.

** A WORKAROUND THAT WORKS ! **
I'm on Vista. I found iTunes unbearably slow and noticed that it uses 54% cpu just when rolling the mouse over the "next page arrow" or moving the mouse over a thumbnail in the appstore. Sometimes I have to wait several seconds for it to do anything. I also noticed that moving the mouse off the thing i clicked on relieved the cpu. Normally, when clicking an item, your mouse remains hovered above the clicked item till the page navigates.
By clicking and then moving the mouse off the element, iTunes navigated instantly!
Reply if this works for you!

T520 - 42435gg / Sound stutter and slow Graphic performance with Intel Rapid Storage AHCI Driver

Hi everybody,
I have serious Problems with my 42435gg
Any time I install the Intel Storage AHCI Driver (I've tried plenty of different versions) which is suggested by System Update I experience a horrible Sound stutter and slow Graphic performance in Windows 7 64-Bit.
The funny thing in this case: If the external e-sata port is connected the problems do not occur. If the port is unused again, the stutter begins immediately.
The only thing I can do is using the Windows internal Storage Driver with which I am not able to use my DVD recorder for example.
The device was sent to lenovo for hardware testing with no result. It was sent back without any repairing.
Anybody experience on this?
Kind regards,
Daniel

Did you try the 11.5 RST beta? Load up DPClat and see if DPC conditions are favorable.
What are you using to check graphics performance?

Firefox 4 is extremely slow to perform any function on my lap top compared to previous versions. Why? And how do I change this!

Firefox 21 and Firefox 22 running on Windows 7 have been reported to take a long time to "wake up" from sleep. I realize hibernation is different than sleep, but... this is the closest match for your description.
Some users have reported that this problem is resolved in Firefox 23 (currently in beta). Others have had inconsistent luck with minimizing Firefox before letting Windows sleep and other measures.
Please check out this (very long) thread for more information: [https://support.mozilla.org/questions/961898 browser freezes after resuming from sleep]
Or jump to the part about Firefox 23: https://support.mozilla.org/questions/961898?page=3#answer-457321
The fact that this just started recently suggests perhaps it is related to another program or update, but I don't think anyone has confirmed the exact interaction that causes the problem.

Kapsel Fiori Client (FC): self-built iOS FC shows very slow UI performance

Hi Experts,
I have used KapselSDK to build our own FC using:
SMP3.0 KapselSDK SP07_PL00
Cordova 3.6.3
Xcode 6.2
OS X 10.10.2 Yosemite
Enterprise distribution certificate for deplyment
.ipa for iPhone4S, 5 (tested)
ipd also inside Airwatch (tested)
App config:
SMP proxy is not used.
The issue:
We use FC to launch the Fiori Launchpad where there are some Fiori apps. The problem is that after type usr pwd, it took very long time to see the Launchpad UI. Tried the standard FC from Apple Store, and it worked very fast.
Does anyone have any idea? I see some info about the slow UI performance for Android devices which can be solved using crosswalk, but my understanding is that crosswalk is not for iOS.
Thanks.
Dong

Have you tired testing the same URL through Mobile Safari to see if it is slow also?
We have had reports of slowness on iOS and we are researching. The details are iOS uses HTTP pipelining when the connection is slow. This means iOS bundles several requests (2-3 to our observations) together but the ICM does only response to one of them and ignores the others. After a timeout of about 1 minute (transparent to the FLP) the Safari automatically repeats the ignored requests. It may happen that this happens a second time, but not a third time – then the requests are not repeated anymore. Seems to happen in Mobile Safari Browser more often than Fiori Client and doesn't happen in Mobile Chrome on same device.
Thanks,

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS

EXTREMELY SLOW XQUERY PERFORMANCE AND SLOW DOCUMENT INSERTS.
Resolution History

### Complete Problem Description ###
A test file is being used to do inserts into a schemaless XML DB. The file is inserted and then links are made to 4
different collection folders under /public. The inserts are pretty slow (about
15 per second and the file is small)but the xquery doesn't even complete when
there are 500 documents to query against.
The same xquery has been tested on a competitors system and it has lightening fast performance there. I know it
should likewise be fast on Oracle, but I haven't been able to figure out what
is going on except that I suspect somehow a cartesian product is the result of
the query on Oracle.
### SQLXML, XQUERY, PL/SQL syntax used ###
Here is the key plsql code that calls the DBMS_XDB procedures:
CREATE OR REPLACE TYPE "XDB"."RESOURCEARRAY" AS VARRAY(500) OF VARCHAR2(256);
PROCEDURE AddOrReplaceResource(
resourceUri VARCHAR2,
resourceContents SYS.XMLTYPE,
public_collections in ResourceArray
) AS
b BOOLEAN;
privateResourceUri path_view.path%TYPE;
resource_exists EXCEPTION;
pragma exception_init(resource_exists,-31003);
BEGIN
/* Store the document in private folder */
privateResourceUri := GetPrivateResourceUri(resourceUri);
BEGIN
b := dbms_xdb.createResource(privateResourceUri, resourceContents);
EXCEPTION
WHEN resource_exists THEN
DELETE FROM resource_view WHERE equals_path(res, privateResourceUri)=1;
b := dbms_xdb.createResource(privateResourceUri, resourceContents);
END;
/* add a link in /public/<collection-name> for each collection passed in */
FOR i IN 1 .. public_collections.count LOOP
BEGIN
dbms_xdb.link(privateResourceUri,public_collections(i),resourceUri);
EXCEPTION
WHEN resource_exists THEN
dbms_xdb.deleteResource(concat(concat(public_collections(i),'/'),resourceUri));
dbms_xdb.link(privateResourceUri,public_collections(i),resourceUri);
END;
END LOOP;
COMMIT;
END;
FUNCTION GetPrivateResourceUri(
resourceUri VARCHAR2
) RETURN VARCHAR2 AS
BEGIN
return concat('/ems/docs/',REGEXP_SUBSTR(resourceUri,'[a-zA-z0-9.-]*$'));
END;
### Info for XML Querying ###
Here is the XQuery and a sample of the output follows:
declare namespace c2ns="urn:xmlns:NCC-C2IEDM";
for $cotEvent in collection("/public")/event
return
<cotEntity>
{$cotEvent}
{for $d in collection("/public")/c2ns:OpContextMembership[c2ns:Entity/c2ns:EntityIdentifier
/c2ns:EntityId=xs:string($cotEvent/@uid)]
return
$d
</cotEntity>
Sample output:

Does loading too many classes into jvm slow down performance?

hi all,
does loading too many classes into jvm will slow down performance. Our application is CPU bound, if we use any framework we need to load all the classes related to that framework in JVM. Does this have any effect on the performance of the JVM.
thanks and regards,
akmal

does loading many classes into jvm slow down performance.It will increase the time it takes for the JVM to load your application.
Our application is CPU boundThe time it takes the JVM to load your application is not likely to be an issue for you then.

Jdbc thin driver bulk binding slow insertion performance problem

Hello All,
We have a third party application reporting slow insertion performance, while I traced the session and found out most of elapsed time for one insert execution is sql*net more data from client, it appears bulk binding is being used here because one execution has 200 rows inserted. I am wondering whether this has something to do with their jdbc thin driver(10.1.0.2 version) and our database version 9205. Do you have any similar experience on this, what other possible directions should I explore?
here is the trace report from 10046 event, I hide table name for privacy reason.
Besides, I tested bulk binding in PL/SQL to insert 200 rows in one execution, no problem at all. Network folks confirm that network should not be an issue as well, ping time from app server to db server is sub milisecond and they are in the same data center.

I have exactly the same problem, I tried to find out what is going on, changed several JDBC Drivers on AIX, but no hope, I also have ran the process on my laptop which produced a better and faster performance.
Therefore I made a special solution ( not practical) by creating flat files and defining the data as an external table, the oracle will read the data in those files as they were data inside a table, this gave me very fast insertion into the database, but still I am looking for an answer for your question here. Using Oracle on AIX machine is a normal business process followed by a lot of companies and there must be a solution for this.

Continued SLOW online performance after two Archive & Installs

Hi.
I have been living with slow online performance – pages slow to load, movies very slow to load, movies don't play back smoothly, constant buffering – for some 3-4 months before trying to do something about it... (this timeline coincides with a potential Security Update 2008-006 issue discussed here: http://discussions.apple.com/thread.jspa?threadID=1730909&tstart=0 , but I don't have enough savvy to know if that's the problem.)
Equivalent slow performance in both Safari and Firefox... I've compared the same sites I visit on other peoples workstations, PC and Mac, various ISPs – all of their pages and movies light up and play instantly.
Tried to research and do as much as I could before coming here, but I don't have great diagnostic skills... here's what I've got so far:
By late November, I managed to eliminate the ISP (Earthlink) as a cause of the problem... however, due to their direction to change DNS numbers, I can no longer automatically connect online upon booting, but must repeatedly connect via Internet Connect (separate issue?)... via these forums, I've reset the DNS to 208.67.220.220, 208.67.222.222.
Neither hard drive is even half full.
I did an initial Disk and Permissions Repair prior to first A&I... they needed repair then, but subsequent verifications check out clean.
After the first A&I (using the original OS X 10.4 install disk), I downloaded a complete full 10.4.11 update, including all current Security Updates... performance wound up much the same as before.
After the second A&I, and before any updating, I tested online performance – still slow... this time I downloaded only the Mac OS X 10.4.11 Combined Update from November 07, looking to avoid the 2008-006 Security Update... general browsing speed is slightly improved, but any site with a movie or rich graphics behaves like dial-up, as before... Mail is just ok – not fast, but not problematic.
Otherwise, the Mac works well enough, but it's never been a real speed-burner, imo... mainstream graphics apps (Adobe CS2, Quark 6)... the only atypical thing I might have is a Wacom graphics tablet (Intuos 3), but it's always worked fine... no games or brand-X playtime software.
The only other thing I'd be suspicious of is Network Settings, after getting the runaround at Earthlink... but the fact that I can get online at all might rule that out.
I've been at this for days, and am out of ideas... little help?
Thanx.

OK, network settings is the scary stuff that I DO NOT understand...

I found the PPPoE subpane.
Made the New location, it seemed to work briefly, then didn't, then I fumbled my way back to prior settings... I'm willing to try it again, BUT...
What scared me was that after setting New Location, the browser window opened to something called *Internet Configurator*, never seen this before... it asked for my email and password... is this normal?... I've got major privacy and security concerns and DO NOT want to put that password out there if I don't have to.
Please advise before I do this... thanks.

SLOW report performance with bind variable

Environment: 11.1.0.7.2, Apex 4.01.
I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?

Patrick, interesting insight. Thank you.
The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
Here's what I've learned since my last post:
I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
To get performance up to acceptable levels I have changed my function returning query to:
1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?

SQL: System locks up and runs slow after performing simple DML record insert

SQL Version: 2008 R2
I am having a serious problem. I ran the following code to perform a simple table record insert which ran successfully. However, after running this code I could no longer access the related table. I couldn't run a query against it.
I tried to delete all the records and that wouldn't work either. When attempting to run any DML statements (i.e. Select * From vPCCertificateTypes) against this table SQL gets locked up and never returns anything and no error messages. I have
to manually stop the query. Now the entire SQL system is running slow.
Any help would be greatly appreciated. The code I ran to originally insert the records is below.
Regards,
Bob Sutor
CODE:
Begin TRAN
INSERT INTO vPCCertificateTypes (VendorGroup, CertificateType, Description, Active, Category)
SELECT HQCo, 'MBE', 'Minority-owned Business Enterprise', 'Y', 'Affirmative Action'
FROM HQCO
Where HQCo IS NOT NULL
AND HQCo <> 100
AND HQCo <> 99
IF @@ROWCOUNT <> 44 ROLLBACK ELSE COMMIT

The problem was an open uncommitted transaction against the table as you suspected. I ran your code and it cleared the transaction. In the past I would intentionally leave our the Commit statement and then if the transaction ran fine, I would
simply highlight and run 'COMMIT' and it would close the transaction. Apparently that is not the correct approach. I'll use your suggested code from now on.
Thanks for the help.

Slow System Performance after binding Machine to OD

Hello,
I've recently installed Leopard Server using standard configuration. I bound two machines to test and I noticed immediately that I took a performance hit speed wise just doing regular stuff like opening applications and browsing internet takes longer than usual for some reason now they use to pop instantly prior to binding to Server. So I broke the connection to see if the server was causing the lag but both machines for some reason now continue to lag. Does the server alter the client in some way that affects its performance? and why does it still affect the machine after the connection is broke? Any input is appreciated.

Just binding a client to an OD server shouldn't make any noticeable difference in speed, assuming that the network is set up correctly. Network homes certainly will slow you down compared to local homes.
