  There is no single simple answer to optimize performance.

  However, you can usually improve performance by learning how to use cacheAsBitmap and cacheAsBitmapMatrix and they often give the biggest improvement with the least effort.

  Here is an excerpt from a chapter in development of Flash games: in a Social, Mobile and 3D world

  Chapter 7

  Optimize the performance of the game

  Easier to the more difficult to implement

  1. do not use the filters.

  2. always use the reverse for loops and avoid loops and avoid while loops.

  3. explicitly stop timers for their loan for gc (garbage collection).

  4. use the weak event listeners and remove headphones.

  5. strictly type variable when possible.

  6. explicitly disable interactivity mouse when interactivity smile not necessary.

  7. replace dispatchEvents with callback functions whenever possible.

  8 it would be gc stop sounds for the sounds and SoundChannels.

  9. use the DisplayObject most basic need.

  10. always use cacheAsBitmap and cacheAsBitmapMatrix with air applications (i.e., mobile).

  11. reuse of objects when possible.

  12 Event.ENTER_FRAME loops: use different listeners and different listener functions applied to DisplayObjects as little as possible.

  13. the pool instead of creating objects and gc objects ' ing.

  14. use partial blitting.

  15. use step blitting.

  16 use Stage3D.

  Biggest advantage less

  1. Use the blitting Stadium (if there is enough memory system).
  2. Use Stage3D.
  3. Use partial blitting.
  4. Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
  5. Disable explicitly interactivity mouse when interactivity smile not necessary.
  6. Do not use filters.
  7. Use the most basic necessary DisplayObject.
  8. Reuse objects whenever possible.
  9. Event.ENTER_FRAME loops: use different listeners and different listener functions applied to DisplayObjects as little as possible.
  10. Use reverse for loops and avoid the do loops and while loops.

• improve performance on WHERE "ABCDEFGHIJK" AS FIELD | '%'

  Hi all
  
  I have several tables with a constant number of cases (between 1000 and 1 million) and an indexed field (usually a primary key) I need mark from a PL/SQL function. The database is 11.2.0.2.0 on RedHat.
  To make it simple guess this:

  CREATE TABLE A (A VARCHAR2(20) CONSTRAINT A_PKEY PRIMARY KEY);
  INSERT INTO A VALUES ('ABCD');
  INSERT INTO A VALUES ('ABCDEF');
  INSERT INTO A VALUES ('ABCDEFG');
  INSERT INTO A VALUES ('ABCDEFGH');
  INSERT INTO A VALUES ('AACDE');
  INSERT INTO A VALUES ('AACDEFG');
  INSERT INTO A VALUES ('AACCDDD');
  -- between 1000 and 1 million inserts
  COMMIT;
  ANALYZE TABLE A COMPUTE STATISTICS;

  I need the file with the longest field value corresponding to the front of a particular value, for example "ABCDEFGHIJKLMN". The correct result is 'ABCDEFGH '.
  A simple solution is this:

  SELECT * FROM (
    SELECT * FROM A WHERE 'ABCDEFGHIJKLMN' LIKE A || '%' ORDER BY LENGTH(A) DESC
  ) WHERE ROWNUM = 1;

  The problem is that the DB is not efficiently using the index (EXPLAIN the PLAN said Index Full Table Scan or Full Table Scan).
  My real solution is to query from the longest possible values:

  DECLARE
     RESULT VARCHAR(20);
  BEGIN   
  FOR LEN_PREFIX IN REVERSE 4..LENGTH('ABCDEFGHIJKLMN') LOOP
      BEGIN
          SELECT A INTO RESULT FROM A WHERE A=SUBSTR('ABCDEFGHIJKLMN',1,LEN_PREFIX);
          EXIT;
      EXCEPTION        
          WHEN NO_DATA_FOUND THEN
              RESULT := NULL;
      END;
  END LOOP;
  -- Do something with RESULT (it can be NULL too)
  DBMS_OUTPUT.PUT_LINE('RESULT: ' || RESULT);
  END;

  Is to use the primary key well and the query is compiled (not dynamic, it is located in a Package + PL/SQL function).
  What I don't like is that I'm running several queries (end with one exception) before obtaining the final result of "ABCDEFGH".
  Since I was 50 million to different values of 'ABCDEFGHIJKLMN', to the query it is increase the number of queries per about 5 times (or more)!
  
  Perhaps another simple solution is to place all the values in a list and then apply the ORDER BY to get the longest value:

  SELECT MAX(A) KEEP (DENSE_RANK LAST ORDER BY LENGTH(A)) FROM A
  WHERE A IN ('ABCDEFGHIJKLMN', 'ABCDEFGHIJKLM', 'ABCDEFGHIJKL', ... , 'ABCD');

  Explain the Plan said SORTING (ITERATOR INLIST (INDEX UNIQUE SCAN))).
  Because I want a compiled query I need to replace this list in a nested table or other objects (not sure which is better).
  But this solution has the disadvantage that any Oracle internally makes a query for each possible value such as the explain Plan tells me. While with the LOOP FOR that above, I'm from the longest to the first found value.
  
  Here's the code using a nested table:

  CREATE TYPE A_TABLE_TYPE IS TABLE OF VARCHAR2(20);
  /
  DECLARE 
       ALIST A_TABLE_TYPE := A_TABLE_TYPE();
       RESULT VARCHAR(20);
  BEGIN
  FOR LEN_PREFIX IN 4..LENGTH('ABCDEFGHIJKLMN') LOOP
      ALIST.EXTEND;
      ALIST(LEN_PREFIX-3) := SUBSTR('ABCDEFGHIJKLMN',1,LEN_PREFIX);
  END LOOP;
  SELECT MAX(A) KEEP (DENSE_RANK LAST ORDER BY LENGTH(A)) INTO RESULT FROM A
  WHERE A IN (SELECT * FROM TABLE(ALIST));
  -- Do something with RESULT 
  DBMS_OUTPUT.PUT_LINE('RESULT: ' || RESULT);
  END;

  I don't know if a nested query is preferred instead of the DENSE_RANK (I need other fields in the record).

  SELECT * FROM (
    SELECT * FROM A WHERE A IN (SELECT * FROM TABLE(ALIST))) ORDER BY LENGTH(A) DESC
  ) WHERE ROWNUM=1;

  Can I add fields, indexes, or whatever is needed to improve performance. Not sure if a partition is useful since they are small tables in any case (although with the number of records).
  
  Any help is welcome,

• Improved performance in vCenter

  Hello all - I hope that the community can help out me with this one.  It is related to the performance of vCenter.

  VirtualCenter arrived at the point where it's VERY slow almost all the time and I cannot understand why.  As examples, in the computers view models, and virtual VC locks up often for anywhere from 20 to 60 seconds, just by selecting one data center to another.  RVTools almost 20 minutes to come.  Also, if I try to install VeeamONE or VeeamBackup, they are slow slow is not usable and sometimes lower VC (so Veeam is not running - I just wanted to give an example).  Finally, if I restart the server (VM) VirtualCenter, it can sit to 'Apply the settings of the computer' for about 20 minutes.

  I support a vSphere environment that consists of the following

  vCenter: 5.0 Update 1 - running on a virtual of Win2k8R2 computer with 8vCPUs and 20 GB of memory

  SQL Server VC: 2008R2 SQL - running on a VM Win2k8R2 with 8vCPUs and 32 GB of memory

  MUV: VM dedicated

  VC Web: VM dedicated

  * The four run VMs on a dedicated Cluster 2 nodes 'management' which consist of two HP DL380p G8s DualProcs & a lot of memory. No other virtual machines running on the host & loans are all practically zero.

  He currently manages 316 ESXi hosts (all 5.0 Update 1) and about 6000 virtual machines.  When VC was installed, I chose the "Large" scale that we will add more than about 200 guests & about 1000 VMs more next year.  The use of the Cisco Nexus1000v ESXi hosts (excluding the 2 cluster nodes mgmt - those that are on the standard vswitches).

  The hosts and virtual machines are in data centers about 20 & 30 clusters, physically dispersed across the country (US).

  Any thoughts on how to make it better?

  Thanks in advance!

  From there, should I run the script to purge old data from the other KB, or should I expect to see improved performance immediately?

  Yes, but... To do the purge your vCenter Server Service must be stopped.  Always better this offline.  We usually do maintenance on our vCenter DB about each quarter.

• How views can improve performance

  Hello

  Can someone explain to me how the views can improve the performance

  When DMLoperations perform through VIEW rather than perform DML operations by table.

  Thank you and best regards,

  Hi Ibrahim.

  A view is not much more than a macro which is developed by the SQL engine when running. Generally speaking, views will not improve performance.

  You can take the help of INDEXED VIEWS to improve performance. Then, views have clustered index assigned and, when they do, they will store the temporary results that can speed up queries that result. These views can speed up and simplify the application design.

  What is the INDEXED VIEWS?

• ReceiverThreads JMS connector in 10.1.3.3 layout to improve performance?

  Gurus,
  
  I use nonBlockingInvoke = true property in bpel.xml to spawn a thread for each parallel flow activity.
  
  However, the definition of this property I found success in performance. I suspect that the parameter of ReceiverThreads to be the question JMS connector. If ReceiverThreads more could hear in the queue, you can improve performance. (Page 47 of the 10.1.3.1. Performance Document).
  
  But I'm not able to locate this property in orion-ejb - jar.Xml. This property holds a different file or this property needs to be added (please can you provide the exact code)?
  
  Thanks a ton!
  SP

  You can find the documentation of ReceiverThreads here:
  http://download.Oracle.com/docs/CD/B32110_01/Web.1013/b28958/JMS.htm
  (Table 4 - 11).
  There is above the table of examples that show how to add a property.
  (A property can be added to orion-ejb-jar. XML or ejb - jar. Good XML if you set the property via a file .xml orion-ejb - jar.xml is recommended because it is a specific OC4J parameter).

  Alternatively, you can set via the annotation. See here:

• How can I improve performance Adobe CS5?

  I got a trial of Adobe Creative Suite 5 on a PC at work and so far it's ok, but it's really trolling. The PC currently has an Intel Core 2 Quad Q9400 2.66 GHz, 4 GB of Ram DDR2, 160 GB HDD, and an integrated Intel graphics chip.

  Add a dedicated graphics card will improve performance of CS5? I read on the forums that Mac users use a 2nd hard drive as a "scratch disk" for the likes of photoshop which improves performance but do not know how to implement that.

  Any ideas would be great.

  The integrated graphics may well take all system RAM. In addition, you enter your operating system but I recommend Win 7 64 bit with a boat load of RAM.

  Fast hard drives with a drive of dedicated work will help, too.

• Super Proxy? Improve performance more?

  http://help.Adobe.com/en_US/AfterEffects/9.0/WSF13D6BED-c53b-408a-B2D6-C8B4205D4FB7a.html

  Apart from these tips from Adobe on improving performance, does anyone know any other tips?... even if it is a purchase of third party. It seemed that just when mandated, the machine still flat enough to annoy me and theyre proxy/lowres images is of course a bit blurry. I guess Im hoping there are some great plugin proxy that allows you to work superfast. The dream is to create animations 3D HD on a laptop. FTP then all in a cluster, and they do most of the work and send me a nice shiny bluray.

  No, sorry. There is no magic recipe. Computational mathematics defeated this dream. AE is a full buffer rendering engine, which means that everything that this process must adapts perfectly to the RAM. So, if your machine is not at the height - well, you know the story. That will change only when AE Gets a converter in mosaic or a user-friendly method to same memory or knows how to deal with a lot more RAM in a 64-bit version. So far, these solutions will have to get by.
