Code optimization
Can anyone please tell me how to optimize this section in order to make it run faster? It gets extreamly slow with the increase in array size.
Thanks in advance!

First of all, you need a FOR loop, not a while loop. Now you can use autoindexing on the two input arrays, eliminating the index array functions and the comparison operation. The "# found" is not even needed! .
Your problem is that the final array size is not known before your loop starts....
...BUT you can calculate it by calculating it in a seperate loop beforehand! NOW you can initialize the final array size and use "replace array element" as shown.
(Attached is a simple example, please verify operation with some real data. It might need a tweak or two. )
How big do your arrays get?

Optimizing the # of threads to do code optimization
Hi:
Is the number of threads used in the server to perform the code optimization tuneable? Cust has a large app and server startup is VERY long (1hour+)
vs 15 mins with -Xnoopt) due to optimization processing. Can the # threads used for this be increased via some start switch?
thx.
/WTry with -XXoptthreads, reference here:
http://download.oracle.com/docs/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionXX.html#wp1024195
I believe the default is 1, try using 2 instead. More than that probably won't help much unless it's a large server (many CPUs).

Code optimization - how can I optimize ?
Basically i_mara has 19,000 records and it loops for all recors as coded.
The program is taking much time when i_mch1 has 300,000 records(approximately 40 minutes).
But in case i_mch1 had 18,000 records, it is fast.
Below is the code:
FORM output_itab4_normal .
FIELD-SYMBOLS : <lwa_makt_maktx> TYPE tt_makt_maktx,
<lwa_prfrq> TYPE tt_prfrq,
<lwa_mch1> TYPE tt_mch1,
<lwa_mvke> TYPE tt_mvke.
LOOP AT i_mara INTO wa_mara.
READ TABLE i_mch1 WITH KEY matnr = wa_mara-matnr
ASSIGNING <lwa_mch1>.
IF sy-subrc = 0.
*-----For Recurring Inspection, go to marc table.
READ TABLE i_prfrq WITH KEY matnr = wa_mara-matnr

Please help me . Thanks in advance.Hi,
You can refer to the following likns:
Code optimization
code optimization
Code Optimization
or
you can try this coding too As this avoids any looping and hence improve performance
Create another temporary internal table ie. i_final_temp.
then do the following:
referesh i_final_temp.
append lines of i_final to i_fianl_temp.
delete i_final_temp where v_box ne 'X'
describe table i_final_temp lines v_counter.
Thank You.

Hi masters, nice to cyber with you agian.
I have just come back from NI DAY and I have heard there about Labview Code
Optimization.
I think this is really very interesting so I would like to learn more about
this but, where?
Do you know any good site ?
Maybe Greg could help?

I did a presentation at NIWeek that covers some common performance
problems and has some VIs that show how different techniques compare.
Goto to
ftp://ftp.ni.com/support/niweek/software_track/
and you can find the Optimization presentation, or at least the VIs
used. I'm on a Mac; so I'm not certain what is in there.
The Optimization presentation isn't strictly focused on code speed, and
spends more time on things like panel appearance, but it does cover
performance to a certain extent. It tries to cover some of the mo
st
common issues. The performance chapter in the User manual, used to be
chapter 29, covers the issue pretty well too. Finally, there are some
low level Tech Notes somewhere on the NI web site.
If you have specific questions, post them away.

Code Optimization for handling large volume of data
Hi All,
We are facing a problem when executing a report... lot of time is taken to execute..... Many a times the program is terminated with a dump that "Timeout :Program terminated because of endless loop".
the internal table which has to looped has more than 8.5 lac records...
and for each run of loop there are two read and one select statement (unavoidable)...,,
(We have followed almost all the optimization techniques,,,,)
Please suggest if you have any idea as to ... what can be done in such situation....
Thanks and Regards,
Sushil Hadge.Hi Martin,
Following is the piece of code.....
SELECT bukrs gpart hkont waers
FROM dfkkop
INTO TABLE it_dfkkop
WHERE bukrs = p_bukrs AND bldat IN so_bldat AND hkont IN so_hkont.
SORT it_dfkkop BY gpart.
Loop at it_dfkkop into wa_dfkkop.
<Read statement>
<Read Statement>
ON CHANGE OF wa_dfkkop-gpart.
SELECT gpart hkont waers betrw FROM dfkkop INTO TABLE it_subtot WHERE hkont = wa_dfkkop-hkont AND gpart = wa_dfkkop-gpart.
IF it_subtot IS NOT INITIAL.
LOOP AT it_subtot INTO wa_subtot.
v_sum = v_sum + wa_subtot-betrw.
ENDLOOP.
Endif.
Endon.
Endloop.
Please suggest if this can be improved in some way....
Thanks ,
Sushil

Yet another question on code optimization
Hello again
Sorry for asking too many questions, but I really want to learn how to simplify my work.
Let's say I have this ArrayList that gets initialized every time a user clicks on a new combobox item and a set of numbers are added to it. I then add this arrayList to another arraylist that is initialized outside of the actionlistener class.
So basically every time the user clicks the inner arraylist is added to outer arraylist. But I don't want to have duplicate results if the user chooses to go back to the previous JTextAreas and delete the contents to start typing new stuff. The way i am doing this is like this:
ArrayList<String> filler = new ArrayList<String>(); //The filler that has to be unique, so the user won't screw with the pattern
filler.add("A*?1qkQOz]4X1QedyhA`H-6$U[I{]0n<RT.W})(J+z7o.<q[g5[y0YA2tv+c@WN");
//For each JtextArea object add a filler so that no Nullpointerexception happens with the use of arraylist.set()method....
for (int i = 0; i <textAreaObjs.size(); i ++){
allValues.add(filler);
//Replace the unique filler with the actual user input saved in innerList which is of type ArrayList.
allValues.set(textCounter,innerList);
//Remove all the unnecessary fillers
for (int outerArrayCounter = 0; outerArrayCounter < allValues.size(); outerArrayCounter ++){
for (int innerArrayCounter = 0; innerArrayCounter < allValues.get(outerArrayCounter).size(); j++){
if (allValues.get(outerArrayCounter).get(innerArrayCounter).equals("A*?1qkQOz]4X1QedyhA`H-6$U[I{]0n<RT.W})(J+z7o.<q[g5[y0YA2tv+c@WN")){
allValues.remove(outerArrayCounter);
outerArrayCounter--;
break;
}I tried the different methods of the ArrayList like arraylist.set() and if there is a null at this location: do this, if not do something else but they returned Nullpointerexceptions...
I tried the isEmpty method too but that only checks to see if the whole list is empty and not specific parts of the array....
Is there a better, faster, and simpler way of doing this?
Thanks for the help.I thought this might help... an example of a Sorted[Descending]Map of Lists... I didn't tackle the "frequency aspect" I just generated a random "key" for the map... and a random string to stuff in the Word...
I presume your Word is {String word, int lineNumber, int startIndex} from the source-document... and now you need to query your frequency table for "the most common word" or maybe "the top five words".
You can fill in the blanks.
... and BTW... If I where doing this for real I'd be awfully tempted to extend TreeMap into a "generic" DescendingTreeMap, which I would stick somewhere in my common utils package, from whence it could be reused in future by myself and others.
If you want the code for krc.utilz.RandomString just ask.

Hi there.
Almost embarrassing question, but it will help me with make
my code MUCH more efficient.
I am a newbie, but writing a pretty complex piece in which
the code repeats itself many times with a minor change.
Basically at this part I am telling many different Movie
Clips to pop up in different X and Y's.
I know my code (see example attached) is the long way to do
it.
The 2 paragraphs below are repeating 12(!) more times in my
code and they are exactly the same (but the X and Y's)
I am hoping to find a way to concise the 14 blocks of code (2
here on the example) to one block with +1, and for the different X
and Y's add an if statement for each different situation.
but i am heaving trouble executing it.
Any thought?
Will appreciate any help!
ThanksThanks again for replying.
The last piece of code is doing a great job in shortening the
code.
But I still have issues with the earlier help, although it
makes sense I have been spending the past two days in trying to
solve it…
The older 12 blocks version works great with the collision
detection solution. So I am trying to get the amazing result of
shortening them both, but I am out of luck.
I believe it might have to do with the vars I am using of the
makeTile…
hoping you are not getting tired of reading my posts..
I really don’t know what to do.
here is some code to make it more clear.
again any help will be great, I am loosing it :-( -
Hi All,
I have called the function module - 'CS_BOM_EXPL_MAT_V2' with respective parameters. Following the function call, i have written these lines, to display each material & the corresponding field from MARC. There is no syntax error, but the execution of this query takes a very long time, i had to terminate the execution.
May i know what could be the reason for this?
Code
IF SY-SUBRC EQ 0.
LOOP AT IL_STBX INTO HL_STBX.
WL_MATNR = HL_STBX-IDNRK.
SELECT SINGLE WEBAZ FROM MARC INTO WL_WEBAZ
WHERE MATNR EQ HL_STBX-IDNRK.
ENDLOOP.
Note: I have declared the DATA as mentioned below.
DATA :
IL_STBX TYPE TABLE OF STPOX,
HL_STBX TYPE STPOX.
REFRESH :
IL_STBX[].
CLEAR
HL_STBX.
Await your inputs.
VivekHi,
I believe i have made a fundamental error & that is the reason the program is going on a infinite loop. I just checked with the debugger, the program enters the 'Record Processing' section, reads the function module explodes the BOM, reads info from MARC table, upto this point it is ok. But what is happening is, the execution of the program does not stop after reading the BOM once, it keeps re-reading the BOM & that is why it is on an infinite loop.
Can you let me know how i can limit the execution of this program to read the BOM only once.
Hope i was able to put across the problem. Await your inputs.

Code Optimizations from Compiler?
I have 2 questions:
1) When Flex compiles a SWF/SWC, does it remove all the whitespace to make the files smaller? Just wondering because I'm looking at some javascript projects and many of them have both a "myFile.js" and "myFile.min.js", where "min.js" is the file with all the whitespace removed, making the file much smaller.
2) Does [Bindable] create a conditionally dispatched event (it's not dispatched if there's no event listener), or does the generated code say "dispatch event whenever property changes, regardless"?Hi,
1) When Flex compiles a SWF/SWC, does it remove all the whitespace to make the files smaller?
SWF does not contain source code. Flex (or Flash) compiles actionscript to bytecode. Then Flash player executes it. -
Need Help in code optimization
Hi Experts,
Its a performance issue. I used simple program to find the combinations based on the input.
For Example if input is : 123,
then the possible combinations are,
23 - without 1.
13 - without 2.
12 - without 3.
123
1
2
3
Like wise i need to find the combination for each input. I developped the code and its working fine upto
13 digit input[1234567890123].
But for then 13 digit it took long time to find the combination. Im in the need of reduce the of execution.

Measuring Performance Of CSS Optimizations?
Hi,
I'm relatively new to CSS and standards-based coding. I've been trying like crazy to get all my sites compliant and I am beginning now to wonder about optimizations for speed of execution. Things like...
1. Making class names shorter
2. Removing obsolete classes from style sheets
...and so on.
Are there some commonly used metrics for decided whether or not this sort of thing is 'worth it'. ie. how -much- it improves performance to remove an obsolete class that is, say 100 chars long. I know I'm being vague, but I maintain many sites---some have very little traffic and some a lot (well--to me it's a lot). This sort of clean up is very time consuming so I'm just trying to figure out what will give the most bang for buck. It's hard for me to judge because of all the variables: different ISPs, # of users, size of site, size of stylesheets, size of pages, etc.
Any general thoughts?
TIA,
---JCThanks Nancy.
A couple of things, though...
1. Web Page Analyzer -
http://www.websiteoptimization.com/services/analyze/
---Can't get it to 'work'. Always replies with 'no data returned' for my web site http://jchmusic.com/discography.htm
2. CSS code optimizer. * Note: do a site test before you replace old code with optimized code.*
http://www.cssportal.com/generators/optimize.htm*
---It replies with a list of optimisations, which is great, but the Copy To Clipboard doesn't work for me. And the Output to File option doesn't do anything either. Is there a way to 'see' the complete results all in one go?
3. I knew about Dust Me (thanks to you!) but it sure seems -slow-. I was hoping for other options (like the above) to make the process a bit faster.
TIA,
---JC -
AppleScript speed difference between 10.4 & 10.5
This post is related to a question I posed in March 2009 (https://discussions.apple.com/message/9226100) regarding the speed difference between AppleScript text handling in OS X 10.5 compared with 10.4.11.
I have recently written a script to search through a text file which is an xml file exported from WorkGroup Manager. The file, which is approximately 1.8 MB, contains all the user names on the school server (just over 1720 of them), their settings and any other information we have added. After adapting some script ideas (using text delimiters and offsets) which I found on the internet to assist with counting the number of users and searching through the information of each one, one at a time, I have a script which works far in excess of my expectations in terms of speed when run under OS X 10.4, but runs slower than molasses in winter under 10.5.
The script counts the number of accounts, extracts each user's log-in name and also their actual name (which we have entered under a 'general info' or 'comments' field - I can't remember exactly where, but it is stored in the file), makes up a complete list of all account names (with the actual name, if present) and also makes up a subset of this information into a separate list which contains only the log-in names of those whose actual name has not yet been recorded on the server, then saves both lists to separate text files.
My original attempts, using some rather clumsy text searching and comparison techniques, took about 1-2 minutes to go through the whole procedure. After some internet searching, head-scratching and a bit more more work, the finished script, when run on my G5 under OS X 10.4.11, takes less than 3 seconds to do all I have described above, including the writing to text files. To say I was pleased would be an understatement!
Because the school/work environment, where the script would be run, is all OS X 10.5 or higher, I thought I should test it out under at least OS X 10.5. The script was developed on my DP 2.5GHz G5 with 8GB RAM running OS X 10.4.11. Using a fresh, clean installation of 10.5 I ran the script and was extremely disappointed. After letting it run for more than 20 minutes and still not finishing, I force quit AppleScript and reduced the number of accounts in the file. 40 accounts took 3 seconds, 60 accounts took 6 seconds, 80 took 11 seconds, 100 took 19 seconds and 120 took 27 seconds. I eventually let the script run right through - total time taken to process 1720 users was 65 minutes, compared to 3 seconds under 10.4.11!
Given that it was tested on the same Mac, with the same amount of RAM, using the same script and the same original text file, the only variable left (that I can think of) is the change of OS version - 10.4.11 vs 10.5.
As was pointed out to me in my previous post, AppleScript in OS X 10.5 handles all text as Unicode and has a greater overhead in processing time as a result. I have implemented the various bits of advice offered by respondents to my original post and changed the way I handled lists, etc. Obviously, if the script works so speedily under 10.4.11, I must have done something right in terms of code optimization/efficiency. It's when that exact same script is run under OS X 10.5 that it slows down incredibly. I even tried it on a 2.66GHz Intel Core 2 Duo iMac running 10.5.8 - it still took 40 minutes and Activity Monitor showed CPU usage by Script Editor constantly above 80% (often well above 90%). Saving the script as an application made no difference in the time taken.
Does anybody have any knowledge about what makes AppleScript Unicode-only text handling so slow? In this case, it is 1300 times slower! Is there any way of coercing/restricting the text handling/parsing to ASCII? If I really have to, I will set up a humble eMac at school with 10.4 on it just to handle large text files quickly with AppleScript, but I would prefer to be able to do it on the normal work Macs which have 10.5 or later on them. As mentioned, under 10.4.11 the script processes the 1.8MB text file with 1720 users and writes results to two files - all within 3 seconds, so I'm not really looking for coding suggestions unless they are directly related to what has changed in AppleScript under OS X 10.5. Without sounding too smug, the script works properly and speedily (at least in 10.4). I really would like to learn about the changes in AppleScript in OS X 10.5 and how to cope with or work around those changes.Hi,

These lines will be slow on Leopard
Getting some text in a variable that contains more than 60000 characters will be slower on Leopard,
but I don't know why it's slower
Here a test script.

set a to "abcdefghij"
set tResult to ""
repeat with i from 1 to 3
set o's t_text to a

set TimeTaken to EndTime - StartTime
set tResult to tResult & " Getting text in the variable which contains " & length of o's t_text & ", (20 times) = " & TimeTaken & " seconds." & return
end repeat
tResult
Here the result on my old G5, 2 x 1.8 GHZ
Getting text in the variable which contains 1310720 characters, (20 times) = 50 seconds.
Getting text in the variable which contains 327680 characters, (20 times) = 12 seconds.
Getting text in the variable which contains 163840 characters, (20 times) = 6 seconds.
The result on the same machine on Tiger is always less of one second.
Also, I try with 20 millions characters on Tiger, the result : getting text in the variable which contains 20971520 characters, (20 times) = 0 seconds.

WebLogic 10.3.2 console hangs when attempting configuration changes
Hi,
I am running:
WebLogic 10.3.2
Windows XP x86 64bit
JRockit JVM 1.6.0
I have done a fresh install (twice) and whenever I start the main admin console and try to create a new server or deployment it just sits there and hangs. There are no other servers setup just the defualt AdminServer in development mode. The only other variable is that I have versions 9.2 & 10.3.0 of WL installed - in seperate home locations however so they should not conflict.
Here's a thread dump........

Is it a Limitation of Named Cache Storage- Fails for large volume ???
I debugged the code which loads data from database into the cache as mentioned in the posting : Pre-loading the Cache from Database during application start-up
Now what this code does is load 869 rows from database into java.util.Map using Hibernate loadAll() method. All is fine uptill this point.
The next step is to putAll the entries into cache i.e. contactCache.putAll(buffer). This is where it hungs for a min and i see org.eclipse.jdi.TimeoutException followed by below exception stack trace

So using the local scheme, you place 869 objects into that cache, correct? Does that work?
I didn't tried with local scheme. But i did try with <read-write-backing-map> scheme as it was giving problem i reduced the size to 100 & changed to local-scheme.
If you would like me to try with local-scheme i would do so but it will not prove anything as we need Hibernate Cache store to do write's
>
Can you explain what the remaining issue is? (What part is failing?)
There are several issues and i am really striving to make it work :)-
Here is the list
- revert back to <read-write-backing-map> scheme so that i can pre-poulate the cache from database so that subsequent reads and writes hit the cache instead of database
- to pre-populate the cache during application start-up . We use Spring 2.5, Hibernate 3.2
- the queryContract(contract) method is similar to Search screen i.e. it takes sample contract object as an argument with some attributes populated. I am using Filter API to return the List of Contract objects based on the search parameters of sample contract as follows
Filter filter = new EqualsFilter(IdentityExtractor.INSTANCE, contract);
Set setEntries = contractCache.entrySet(filter); The above code expects all the attributes of sample contract object are fully populated and if not it throws Null Pointer Exception
For example if date attribute is null then Null Pointer Exception is thrown at the following line
writer.writeLong(2, this.date.getTimeInMillis());
I greatly appreciate the inventor of Tangosol Coherence product responding to my queries on the forum. Hopefully with his help i will be able to resolve these issues :)-
