Tool for measuring execution time?

Hi,
i'm trying to measure the time of some determined methods in my app.
I've tried System.currentMillis(), but i don't get the accuracy i need (System.nanoTime() - from 1.5.0 sdk won't help me neihter).
Does anyone know a simple java tool that i can use to do this ???
I thought about optimized (borland), but i just don't have it :-( also i don't know if it ease to use (and i need this measuring as soon as possible).
Thanks for any sugestion,
ltcmelo

<<In Windows at least the resolution of System.currentTimeMillis() seems to be 10ms.
If the operation that takes 9 ms is called a thousand times, and the one that takes 5 ms is called 20
million times, and the one that takes 1 �s is called 200 million times, all will be fast to measure,
all will come in at zero ms by currentTimeMillis(). It would be useful to know the respective execution times of each method.>>
This is not correct. Windows does have 10 ms. granularity, however if you average many measurements this limitation disappears.
For example let's say that a particular method takes 5 ms. on average and we take 10 measurements. You claim that the 10 measurements will all be 0, whereas the actual measurements will either be 0 or 10 depending on how close the clock was to ticking when currentTimeMillis() was called. For example the 10 measurements might look like 0, 0, 10, 0, 10, 0, 0, 10, 10, 0. If you take the average of these numbers you get quite good accuracy (i.e. 50/10=5 ms. the actual time we said the method took). In principle the average should even get you sub-ms. accuracy.
Try it with jamon (http://www.jamonapi.com). JAMon calculates averages and so gets around the windows limitation. If you are coding a web app then jamon has a report page that displays all the results (hits, average time, totals time, min time, max time, ...). If not then you can get the raw data and display it as you like.
One question for the original poster. Why do you think you need sub-millisecond timings? If you are coding a business app IO tends to be the bottleneck and much greater than sub-millisecond.

Photoshop Touch crashes after selecting "Wrap" tool for the second time

As title says, when selecting "wrap" tool for the second time, Photoshop Touch crashes. It doesn't matter which images and even after reboot and clearing all the RAM, it constantly crashes only when selected for the second time. I'm using this on Galaxy Note 2 so it really shouldn't have issues with RAM or Processing power. I'm not quite sure about other tools but it should be looked into and hopefully more stable version will be release soon!
Thank you
Device: SGH-T889 T-Mobile Galaxy Note 2

Hi,
We just released an update that should take care of that issue.
thanks,

I am trying to use the liquify tool for the first time. I created a new document (RGB/8) and before I place my photo, the liquify option is available. After I place the photo, the liquify option disappears. What am I doing wrong?

For one thing you forgot to mention the version of Photoshop you use.
Did you place the image as a Smart Object? Liquify got Smart-capabilities with Photoshop CC.

Measure execution time with PowerShell

What would be the best way to accomplish following:
1. Get start time and write it to variable
2. Do something
3. Get end time and measure how long it taked from start to end and store the result in variable
I would need the result be in format like this hours:minutes:seconds and to support 24 hour clock so if the execution starts e.g 11:30 and ends 14:30 it shows correct time.

PowerShell already comes with a CmdLet that allows you to measure the time a script block takes to execute, that sounds like what you are after.
See these for more details on Measure-Command:

Measuring execution time

Hi, I had written a program a while back which was
simply loading in an xml file, parsing out a few
tags, and then writing back to the same file. I
thought of a way the parsing could be made more
efficient, and it certainly seems to be running faster,
however I am looking for suggestions on how I could
prove this?
Basically I am looking for a tool that could monitor
the length of time taken for the program to finish, so
I could do this using both versions of the program using
a set data set and compare the results.
Thanks in advance for any ideas/suggestions :)

What is the Cisco tool for measuring traffic of wireless endpoint users

Hi Experts
I am looking to start a Mesh WISP utilizing Cisco Aironet products (1500 series) and would like to know what is the best Cisco (or if the case has to be "non Cisco") product for measuring the amount of traffic from wireless clients connected to my Cisco Mesh.
Basically I want to be able to say User xyz has this IP xxx.xxx.xxx.xxx how much have they uploaded and how much have they downloaded this month.
This also then allows me to integrate multiple business mobile devices into their broadband plans which is something no-one yet offers in my City.
From what I have read Netflow is the measurement technology but how do I take this data and aggregate it by IP / User for billing purposes. Is there something better at it than Netflow? Your expert opinions and suggestions are much appreciated.
Regards
Ty

That sounds like Cisco Wireless Control System (WCS).

Tools for measuring BDB performance

Hi all,
Are there any tools available for benchmarking the performance of BDB ?
Also how to use the test suite available with BDB distribution ?
Thanks,
david.

Hello,
MVCC alleviates reader/writer contention at the cost of additional memory.
When MVCC is not used, readers trying to read data on page X might block for a writer modifying content on page X. With MVCC, the readers will not block. The fact that readers are not blocked will result in better performance (throughput and/or response time).
So, your test should have some "hot spots" which would create this contention. You should have transaction mix of readers and writers. Without MVCC, you'll see that readers block (resulting in lower throughput). With MVCC, you should see that readers continue, thus getting more transactions per second.
As long as the rows that you store in Berkeley DB are smaller than a page size, my opinion is the row size doesn't matter (Berkeley DB does page level locking).
As mentioned above, memory requirements for MVCC are higher, so to get the additional performance benefit, the 4.6.21 run will probably need a bigger cache.
That's the general answer.
This is an interesting exercise. Good luck!
Warm regards.

(Photoshop CS2) It crashes every time I use my brush tool for a long time. Help?

Hi,
I have recently been having some trouble with my photoshop cs2 (it isn't my computer because it is easily quicker them the majority of computer I have been on and it's only a recent problem). I can use all my tools very easily without having any little pauses and it wont crash, but with my brush tool, after using the brush for a long stroke without unclicking it crashes. Well, it pauses for 2 mins- 4 hours (wont let me click on another tool or carry on drawing or select layers and such). Since I am an artist and work on photoshop for a living , not being able to use the brush tool is a huge problem for me. I have no intension of updating my software to cs3/4/5, (as I don't want to pay for all that software and then find that it crashes again). I recently got my new bamboo graphics tablet and it is even slower when using that. This is also a very recent problem so I was wondering if anyone else had had this before and found a way around it?
Thanks!,
-Lithia

I actually believe there are updates for Photoshop itself, not through Mac Software Update. You should check if there are any updates for the product on this website. Photoshop also tends to glitch sometimes. For example, on PSCS4 for Mac, after opening the program, and changing the toolbar to the traditional 2-column style, the quck mask button is totally cut off unless I switch it to the 2-column style twice.

Measure procedure execution time..

Hi,
Is there any possibility to measure how long each of a procedure in database take?? Is that possible for Oracle's V$ views or by performance report like AWR? On the other hand, is that possible to measure execution time for SQL statements, but without using "set timing on".
Best,

Ideal execution time for any program

Hi,
Is there any method to determine the ideal execution time for a program ?
Or else how to determine that ?
I just wanted the max. time that a program can take so that the performance would not be hampered.
Thanks,
Binay.

did you ask for the 'ideal execution time' or 'how to measure execution times'?
The second question was answered in one of your other questions.
Optimization:
Do SQL Trace, go to Summary by SQL statement, check 10 Top contributions (time = duration).
Try to optimize them, note minimal time per record, if larger than 10.000 microsecodns, then you should index usage.
Do SE30, go to hit list, sort by net time, again address 10 Top contributions, try to optimize, check the coding.
Do optimization and trace again, check again 10 Top contributions ....

Can I reduce the execution time for a step in a TestStand ?

Hi,
I calculated the a single step execution time for TestStand Ver 2.0. It comes to around 20 milliseconds/step. Can I reduce this excution time ?
Are there any settings available for configuring execution time parameters except result logging and exception handlings to reduce the execution time ?

It's difficult to tell how you what time you are reporting for your step. Clearly we don't have control of the time it takes your code to execute. However, we are constantly working on reducing the overhead of calling the code. In addition, you don't mention the type of step you are calling. One way to have a common reference is to use the example \Examples\Benchmarks\Benchmarks.seq. Below have have posted the results of running this sequence with both tracing and result collection enabled and then disabled. I have a 700 MHz, 128 MB RAM, Dell PIII laptop. In this example there is no code within the code modules. You notice that calling a DLL has the least overhead with a minimum of 7.459 ms with tracing and results enabled and 0.092 ms with tracing and results disabled. Although not included below, if I enable results be disable tracing I get a minimum time of 0.201 ms, a 100x improvement on your time.
With Results and Tracing enabled.
7.578 milliseconds per step for CVI Standard Prototype - Object File
7.579 milliseconds per step for CVI Standard Prototype - DLL
7.459 milliseconds per step for DLL Flexible Prototype
8.589 milliseconds per step for DLL Flexible Prototype Numeric Limit
9.563 milliseconds per step for DLL Flexible Prototype Numeric Limit with Precondition
10.015 milliseconds per step for DLL Flexible Prototype Numeric Limit with Precondition and 4 Parameters
7.868 milliseconds per step for ActiveX Automation
8.892 milliseconds per step for LabVIEW Standard Prototype
With tracing and results disabled.

Hi prajwal.
I would like to suggest,
It is possible to reduce the time of execution by Increasing the number of fields in the WHERE clause as only those specific number of records are fetched which results in comparatively less execution time.
Also, SAP has designed such powerfull tools like Transactions - ST05, ST07, ST30, and many more
I would like to suggest you a couple of references relating to your case,
[SDN - Reference for Long execution time during processing of a select query|/thread/477540 [original link is broken];
[SDN - Reference for Reducing the Execution time of the program - Tools|How can i reduce time of execution;
[SDN - Reference for solutions to reduce the execution time of a program|How to reduce my query execution time?;
Hope that's usefull.
Good Luck & Regards.

Execution Time Issue

Help Please!!!
I've been searching for an execution time issue in our application for a while now. Here is some background on the application:
Collects analog data from a cDAQ chassis with a 9205 at 5kHz
Data is collected in 100ms chunks
Some of the data is saved directly to a TDMS file while the rest is averaged for a single data point. That single data point is saved to disk in a text file every 200ms.
Problem: During operation, the VI that writes the data to the text file will periodically take many hundreds of milliseconds to execute. Normal operation execution times are on the order of 1ms or less. This issue will happen randomly during operation. It's usually many seconds between times that this occurs and it doesn't seem to have any pattern to when the event happens.
Attached is a screenshot of the VI in question. The timing check labeled "A" is the one that will show the troubling execution time. All the other timing checks show 0ms every time this issue occurs. I simply can't see what else is holding this thing up. The only unchecked subVI is the "append error call chain" call. I've gone through the heirarchy of that VI and ensured that everything is set for reentrant execution. I will check that too soon, but I really don't expect to find anything.
Where else can I look for where the time went? It doesn't seem to make sense.
Thanks for reading!
Tim

You should probably increase how much data you write with a single Write to Text File. Move the Write to Text File out of the FOR loop. Just have the data to be written autoindex to create an array of strings. The Write to Text File will accept the array of strings directly, writing a single line for each element in the arry.
Another idea I am having is to use another loop (yes another queue as well) for the writing of the file. But you put the Dequeue Element inside of another WHILE loop. On the first iteration of this inside loop, set the timeout to something normal or -1 for wait forever. Any further iteration should have a timeout of 0. You do this with a shift register. Autoindex the read strings out of the loop. This array goes straight into the Write to Text File. This way you can quickly catch up when your file write takes a long time.
NOTE: This is just a very quick example I put together. It is far from a complete idea, but it shows the general idea I was having with reading the queue.

Cannot Show Visual Studio 2010 Tools for Applications Editor

I'm trying to teach myself the ins and outs of SSDT (I believe it was formerly called SSIS; correct me if I am wrong).
So, I'm checking to see if a file exists, and I'm following the example here:
http://bidn.com/blogs/DevinKnight/ssis/76/does-file-exist-check-in-ssis
I entered the ReadOnlyVariables and ReadWriteVariables, and as soon I I click on the 'Edit Script' button I see this popup:
What am I doing wrong here? How do I fix this problem? Is something disabled? Do I need to install something?
As an alternative, I tried the methodology I found here:
http://visakhm.blogspot.in/2011/12/simulating-file-watcher-task-in-ssis.html
That looks promising. unfortunately, I don't see anything named 'Check for file presence' in my SSIS Toolbox. unless, this is something I need to create and save in the Toolbox...that's the only thing I can think of. It talks about creating
a script task, so that would make sense. Again, as I mentioned above, I can't create a script task because something isn't setup right, or configured right, or whatever.
Please help me get this working.
Thanks.
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Hi ryguy72,
The issue occurs because the Visual Studio Tools for Applications (VSTA) design-time or runtime is not installed properly. This can be caused by the install order of the SSDT and SQL Server 2012 Integration Services service. Please open the Programs
and Features window, and check which of the following components are not installed (supposing it is a 64-bit SQL Server platform):
Microsoft Visual Studio Tools for Applications x86 Runtime 3.0
Microsoft Visual Studio Tools for Applications x64 Runtime 3.0
Microsoft Visual Studio Tools for Applications Design-Time 3.0
The Microsoft Visual Studio Tools for Applications Design-Time 3.0 component should be missing in your environment. Then, install the correct Design-time or Runtime component from the \redist\VSTA\designtime\ or \redist\VSTA\runtime\ folder of the SQL Server
2012 install media.

Need help Recording SQL Execution Times in Database

Hello,
I have an interesting thing I am tiring to do. I want to record how much time (Wall Clock) it took the database to execute any select statement against o one particular view lets call it CUST_ORDERS_V.
I would like to record who ran it, what the select statement was (SQL Text) and how much time it took and maybe a few other ancillary things if possible.
Looking at most of my requirements took me right to Oracle Auditing and the SYS.AUD$ table. After setting up auditing with:
audit_trail=db,extended
and
audit select on ME.CUST_ORDERS_V by access;I get every piece of information I need except for the execution time! Wow that would be great if Oracle recorded that!!! So I was thinking if I could. I was considering a trigger on SYS.AUD$ (I know evil thoughts) that would look into some V$ view and get the execution time and write it into some custom table with a link back to SYS.AUD$.
This might be the complete wrong way to do it. I was wondering if anyone had any ideas on this.
I am running on 11.2.0.3 EE. I am on EE so I can use Fine Grained Auditing if it is needed. However I DO NOT have the Tuning or Diagnostic Pack.

>
Hi again,
Yes, a complete set of times from end to end would be great. However
for now I need to stick with what is in my domain of control, the database.
Maybe after the DB I will look to get the others.But your point about the operators blaming the db brings up the probability
that after you tell them that the db is not the issue, they'll start to blame
the app server, the cabling, their OS, the browser, the tea-lady...
If you have click===> page, they have no more places to hide and have to
actually work for a living ;)
I do not think I can access v$active_session_history as I do not have the Tuning Pack.Well, presumably there is a business case for this project. Why not tell management
that it's required?
Otherwise, you could go to ashmasters.com - a site run by Kyle Hailey (Oak Table
member and author). He has an Open Source ASH "substitute" which you might
like to try - haven't used it myself, but if Kyle Hailey's behind it, then it's at
least worthy of investigation.
HTH,
Paul...
