You only get a slight improvement in pick-up. Nethertheless, I have done it. I carry my 5800 in a soft pouch and there is room for my spare battery.

How to improve Oracle Veridata Compair pair performance with tables that have big (30-40MB)CLOB/BLOB fileds ?

Can you use insert .. returning .. so you do not have to select the empty_clob back out.
[I have a similar problem but I do not know the primary key to select on, I am really looking for an atomic insert and fill clob mechanism, somone said you can create a clob fill it and use that in the insert, but I have not seen an example yet.]

How to improve on insert-select query performance

Hi,
Would like to get some opinion on how to improve this query inside my stored proc.

How to improve the event log read performance under intensive event writing

We are collecting etw events from customer machines. In our perf test, the event read rate can reach 5000/sec when there is no heavy event writing. However, the customer machine has very intensive event writing and our read rate dropped a lot (to 300/sec).
I understand there is IO bound since event write and read will race for the log file, which is also confirmed by the fact that whenever there is a burst of event write, a dip of event read happens at the same time. Therefore, the event read cannot catch up
the event write and the customer gets lagging behind logs.
Note that most of the events are security events generated by windows (instead of customers).
Is there a way to improve the event read performance under intensive event write? I know it is a hard question given the theory blocker just mentioned. But we will lose customers if there is no solution. Appreciate any clue very much!

How to make my own grid and perform a "snap to grid" effect?

Hi! I am a newbie in flash and I am trying to create a puzzle like game (a chinese puzzle game called tangram). I am wondering what kind of functions should I use to create a "triangular" grid i.e. something similar to this ? http://img40.imageshack.us/img40/2259/triangulargrid.jpg. What should I do to make the movie clips to perform the "snap to grid" effect to this grid?I have tried to draw my own grid and used the "cacheAsBitmap" function to implent it, however it doesnt seems to be working. Is there any suggestions or tutorials to this problem? Thank you very much.

Well, the project you are taking is not a simple one. It requires quite an experience with AS3. It is not a few lines of code but an understanding of Flash display list model and how objects can interact. In addition, there is no a single solution but rather wide array of possible approaches depending on use case.
To illustrate, the code below draws a mesh that replicates the image in your first post. Do you think that this is enough from the standpoint of your AS3 knowledge to get you started?
This code needs Flash 10:
var side:Number = 400;
var s:Sprite = new Sprite();
var g:Graphics = s.graphics;
g.lineStyle(3);
//g.beginFill(0xFF8000);
g.drawTriangles(
     Vector.<Number>([     0, 0, side * .5, 0, side, 0,
     side * .25, side * .25, side * .75, side * .25,
     0, side * .5, side * .5, side * .5, side, side * .5,
     side * .25, side * .75, side * .75, side * .75,
     0, side, side * .5, side, side, side

How to improve performence of function and procedure .Start with tracing the session that executes the functions/procedures and tkprof the trc. file (with wait events).
The tkprof output will give you pointers where you could make some improvement.
You can find many examples on http://asktom.oracle.com, do a search on 'tuning'

How to improve the query performance in to report level and designer level

How to improve the query performance in to report level and designer level......?
Plz let me know the detail view......

first its all based on the design of the database, universe and the report.
at the universe Level, you have to check your Contexts very well to get the optimal performance of the universe and also your joins, keep your joins with key fields, will give you the best performance.
at the report level, try to make the reports dynamic as much as you can, (Parameters) and so on.
and when you create a paremeter try to get it match with the key fields in the database.
good luck

How to improve and maintain performance of droid phones

ive read bits and pieces about how to make the phones faster and stuff but whats the best way of improving the phones performance without overclocking and putting on custom roms and maintaining that performance.

Biggest thing to do is keep the cache cleared out the applications. I recommend once a week check depending on usage.
Keep an eye on your internal storage. Any thing below 30mb needs some serious cleaning of applications, cache, call history, text messages, in that order. I try and keep my internal storage at 50 mb or higher.
Also try and pay attention to your Dialer Storage. It holds the call history and text messages. But it can grow quickly. I found out the hard way. Had some ringtones saved in the text message thread but rarely looked at them. Then one weekend almost six months after I got, I was looking at the thread a lot because a new message had been sent from that number. The dialer storage went from 5mb to 21mb in a couple of days. Even after deleting the entire thread it only went down 1mb. There was no way to clear data for that app so I ended up doing a factory reset. Now Dialer Storage is a baby size of 64 kb!
I never used a task killer only task managers.
I have a battery monitor and have seen no big difference. However I don't use facebook or twitter so I don't have those constantly updating.

->Try to avoid joins and use FOR ALL ENTRIES.
->Try to restrict the joins to 1 level only ie only for tables
->Avoid using Select *.
->Avoid having multiple Selects from the same table in the same object.
->Try to minimize the number of variables to save memory.

->Avoid creation of index as far as possible
->Avoid operators like <>, > , < & like % in where clause conditions
->Avoid select/select single statements in loops.
->Try to use 'binary search' in READ internal table. -->Ensure table is sorted before using BINARY SEARCH.

How to improve the performance of adobe forms

Hi,
Please give me some suggestions as to how to improve the performance of adobe form?
Right now when I' am doing user events it is working fine for first 6 or 7 user events. From the next
one it is hanging.
I read about Wizard form design approach, how to use the same here.
Thanks,
Aravind

Hi Otto,
The form is created using HCM forms and processes. I' am performing user events in the form.
User events will doa round trip, in which form data will be sent to backend SAP system. Processing will
happen on the ABAP side and result will appear on the form. First 6 or 7 user events works correctly,
the result is appearing on the form. Around 8 or 9th one, the wait symbol appears and the form is not
re-rendered. The form is of size 6 pages. The issue is not coming with form of size 1 page.
I was reading ways to improve performance during re-rendering given below.
http://www.adobe.com/devnet/livecycle/articles/DynamicInteractiveFormPerformance.pdf
It talks about wizard form design approach. But in SFP transaction, I am not seeing any kind of wizard.
Let me know if you need further details.
Thanks,
Aravind

Performance blocker on cFP-2020: file-I/O! How to improve?

Hi all,
after resolving my serial-communication problems I still have a performance problem. The code is way too slow which causes e.g. the ftp-server on the fieldpoint to not respond anymore to requests from my PC. I always get timeouts. I also frequently get loop-finished-late events within my two state-machines. I have now used the timing and performance monitor to sse which vi is taking so much time. The result: A file-I/O vi that writes data and log-entries into three different log-files. With a former verion I simply used one vi that appends a string to an existing file. However, since this function disappeared with LV8.2 I had to rewrite the code to use the following sequence of LV-functions:
- file open
- set pointer to the end
- write string
- file close
My vi shich calls this sequence is horribly slow - execution time per run is about 200ms and the top of the list in the performance monitor. Are there any suggestions on how to improve this code? I simply want to add a string to the end of the log-file......
The vi is attached. There are two features in the code which are not self-explanatory: The first sub-vi generates a new file if is used for longer than a preset time (15 minutes in my case). So the create-time of the file is stored in the filename and whenever the current time exceeds create-time plus 15 min. A new file name is created. For simplicity, the name is stored only for the first of the three log-files. The other two are created by string operations from the first filename. Second, whenever a file is "created", that means is does not exist yet, a data-header is written to the file, before data is appended.
Can you see simple improvements here that will accelerate this code? Maybe open the file only once and then append data subsequently and only close it when a new file is created? But I do not need all three files all the times, there may be situations where only one file is needed, and the others need not be created at all.
Thanks,
Olaf

I think moving the open file, move to end of file, and close file out of the loop would certainly help. These functions could be associated with or built into your "determine new file" VI. Since the file paths get passed into the loops, you could pass them through with shift registers so that you can close them after the loops end.
One other thing to look at is your initialize array and insert into array functions. I believe insert into array is one of the costlier functions. Build array would be better. And initializing a much larger array and using replace array subset is better yet. But if you wind up with more elements than you had originally initialized for, you will have to use build array to enlarge it. I would recommend searching the Labview forum for insert into array, build array, and replace array subset for threads that do a better job explaining the differences and advantages of each.
Thanks, that improved the performance of this vi by about two orders of magnitude. The application is now much more stable.
However, I cannot connect to the cFP-2020 anymore by ftp. I even swithed the fieldpoint to boot without vi.
To be specific, I can access the cFP and cd into all directories except for the directory with the data. I assume that there is a large
amount of files in it now, but used to work before even with lots of files. The only thing that might be not so nice is that there is a space
in the folder name, but that has been like that for years now and used to work.
Is there any reason (corrupted file or something like that) that can cause the ftp to fail on this specific directory?
Thanks,
Olaf
...at least I am very close now to a satisfying and running system.... :-)

How to improve performance of MediaPlayer?

I tried to use the MediaPlayer with a On2 VP6 flv movie.
Showing a video with a resolution of 1024x768 works.
Showing a video with a resolution of 1280x720 and a average bitrate of 1700 kb/s leads to a delay of the video signal behind the audio signal of a couple of seconds. VLC, Media Player Classic and a couple of other players have no problem with the video. Only the FX MediaPlayer shows a poor performance.
Additionally mouse events in a second stage (the first stage is used for the video) are not processed in 2 of 3 cases. If the MediaPlayer is switched off, the mouse events work reliable.
Does somebody know a solution for this problems?
Cheers
