Variable response times

Like many I get variable speeds and occasional drop outs, but the question is slightly different so hopefully you will bear with me if I seem to be asking something already answered.
My nominal speed is 2.3 Mbits, though it can drop to around 1.0 Mbits. The problem however is how long sites can take to respond, how slow the page is written to the screen and how variable that can be even with the same site. This is worse (or certainly appears to be) at mid-term and after 4.00 p.m. so I tend to blame school children getting home and going on line! If I check the speed when sites are loading very slowly, more often than not the speed is around 2.0 Mbits, yet at other times sites respond quickly yet the speed is slower. Downloads also vary - start off at 2 or 3Mbits and then drop to almost to the old dial up speeds. Other times they download very (for me) fast.
I believe the contention ratio is to blame, partly because of the school related issue, and partly because switching off the modem for a few minutes can sometimes help, as if I am picking up a less busy "box" at the exchange. Sometimes it solves itself if I try again later so I doubt if it is the modem to blame.
The question is therefore - am I right and if so, is there anything I can do, or if I am wrong can my modem (Netgear DGN 3500) be to blame.
Thanks.

Sorry - been away.
Yes, I had just done a manual reset. I have checked again now that it has been on for a few days. Speed not much different and web page response times are still very slow. The bt.com page for example took about 3 seconds to load and did so in noticable stages.
I have tried two different machines connected via short cable to modem which is connectd to master socket with nothing plugged into any other socket in the house. Not much difference noted. Reminds me of the situation when I was working - sometimes the LAN was very slow because too many people were using it. I suspect the exchange basically can't cope with the load, butthat opinion may well be due to ignorance on my part!

HP Pavilion hard drive response time is very slow but tests pass (evenutally)

I have owned a HP Pavilion M1199a originally running Windows XP, but has been running Windows Vista 32-bit for the last 3 years or more.
The PC started to lock up for 30 seconds or more (2 weeks ago), with the disk light constantly on then go again for no apparent reason. These lock ups have become more frequent and for longer durations. I removed anti-virus software, and a few other applications/services but generally this computer is fairly clean as I use it as a media center PC.
I have tried checking the disk (SATA) for errors, and it passes although the tests take a lot longer than they should. The resource monitor shows no excess CPU usage and there is plenty of memory available. The disk monitor shows response times of 5000-20000 ms.
What is the best way to proceed from here? Is there a SATA controller or motherboard (ASUS PTGD1-LA) test? Should I buy another SATA drive and try that? I suspect that it is either the drive, drive controller and/or the motherboard that is failing but I don't know how to isolate the problem. The computer hardware configuration has remained the same for years.
The OS has the automatic updates enabled and I uninstalled the recent ones in case they were somehow causing an issue.

1/ No, but I am running Vista, so assume this will be the same? Or should I just look at the tmp and temp environment variables to see what folders are being used?
In Vista type temp in the Search programs and files box and double click on the temp files icon that appears above. Delete all the files in the folder that you can. It is safe as they are exactly what they are called and that is temporary files. If you haven't done this ever or in quite a while there should be a noticeable increase in the operating system's response time.
2/ Yes. It completes after a very long time.
5/ No - but will try this out too.

Spry menu response time problems with IE

We implemented the spry vertical menu for showing the
categories of a products catalog. It has almost 1400 categories
organizad at about 5 levels, some categories have about 20
subcategories. These categories are in a coldfusion session
variable.
It works perfect in mozilla, but in IE7 and IE6 in some
computers, present this problem:
- The response time is slow when you change from one category
that has subcategories to ahother. If you see the Windows Task
Manager of the computer while you use the menu, the processor use
go up to the top level.
And the effiecience of the menu decrease.
See in

Thanks,

i dont think you understood my question, wasnt about body background, but abut the spry image slideshow to work properly in IE
I was not talking about body background, but about having markup that screws up your document when using a browser. Body background just happened to be there. Perhaps you would do well to have a look here http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Flittletreats.org%2F.
I have noticed that you ignored my solution; your document still shows two bodies.
Perhaps I should have mentioned that I tested in IE6 through to IE9 using IETester and the above was the only thing stopping IE from performing properly.
How did you determine that the slideshow was not working correctly in IE and which versions of IE?

How to capture transaction response time in SQL

I need to capture Transaction response time (i.e. ping test) to calculated the peak hours and averaged
on a daily basis.
and
Page refresh time that is calculated no less than every 2 hours for peak hours and averaged on a daily basis.
Please assist
k

My best guess as to what you are looking for is something like the following (C#):
private int? Ping()
System.Data.SqlClient.SqlConnection objConnection;
System.Data.SqlClient.SqlCommand objCommand;
System.Data.SqlClient.SqlParameter objParameter;
System.Diagnostics.Stopwatch objStopWatch = new System.Diagnostics.Stopwatch();
DateTime objStartTime, objEndTime, objServerTime;
int intToServer, intFromServer;
int? intResult = null;
objConnection = new System.Data.SqlClient.SqlConnection("Data Source=myserver;Initial Catalog=master;Integrated Security=True;Connect Timeout=3;Network Library=dbmssocn;");
using (objConnection)
objConnection.Open();
using (objCommand = new System.Data.SqlClient.SqlCommand())
objCommand.Connection = objConnection;
objCommand.CommandType = CommandType.Text;
objCommand.CommandText = @"select @ServerTime = sysdatetime()";
objParameter = new System.Data.SqlClient.SqlParameter("@ServerTime", SqlDbType.DateTime2, 7);
objParameter.Direction = ParameterDirection.Output;
objCommand.Parameters.Add(objParameter);
objStopWatch.Start();
objStartTime = DateTime.Now;
objCommand.ExecuteNonQuery();
objEndTime = DateTime.Now;
objStopWatch.Stop();
objServerTime = DateTime.Parse(objCommand.Parameters["@ServerTime"].Value.ToString());
intToServer = objServerTime.Subtract(objStartTime).Milliseconds;
intFromServer = objEndTime.Subtract(objServerTime).Milliseconds;
intResult = (int?)objStopWatch.ElapsedMilliseconds;
System.Diagnostics.Debug.Print(string.Format("Milliseconds from client to server {0}, milliseconds from server back to client {1}, and milliseconds round trip {2}.", intToServer, intFromServer, intResult));
return intResult;
Now, while the round trip measurement is fairly accurate give or take 100ms, any measurement of latency to and from SQL Server is going to be subject to the accuracy of the time synchronization of the client and server. If the server's and client's
time isn't synchronized precisely then you will get odd results in the variables intToServer and intFromServer.
Since the round trip result of the test is measured entirely on the client that value isn't subject to the whims of client/server time synchronization.

How can I improve the response time of the user interface?

I'm after some tips on how to improve the response time to mouse clicks on a VI front panel.
I have data acquistion application which used to run fine, but after spending a couple of weeks making a whole bunch of changes to it I find that the user interface has become a bit sluggish.
My main GUI VI has a while loop running 16 times a second, updating some waveform charts and polling about a dozen buttons on the front panel.
There is sometimes a delay (variable, but up to 2 seconds sometimes) from when I click on a button to when it becomes depressed. I have wired the iteration terminal of the while loop to an indicator on the front panel and can see that the while loop is ticking over during the delayed response to the mouse click, so I know that the problem is not that the whole program is running slow, just the response to mouse clicks.
Also, just for debugging purposes, I have indicators of the iterations of all the main while loops in my program on the front panel, so I can see that there are no loops running abnormally fast either.
One thing I've tried is to turn off multi-threading, and this does seem to work - the response to mouse clicks is much faster. However, it has the side effect of making the main GUI while loop run less evenly. I was trying to get a fairly smooth waveform scrolling across the screen, and when multi-threading is off it gets a bit jerky.
Any other suggestion welcome..
(I am using LabVIEW 7.1, Windows 2000).
Regards,
Mark.

Hi Altenbach,
Thanks for your reply. In answer to your questions:
I am doing both DAQ board and serial data acquisition. I am using NIDAQ traditional for the DAQ board, and VISA for the serial. I have other similar versions of this program that do only DAQ board, or only serial, and these work fine. It was only when I combined them both into the same program that I ran into problems.
The multiple while loops are actually in separate VIs. I have one VI that acquires data from the DAQ card, another VI that acquires data from the serial port, another VI that processes the data and saves to file, and another VI, the GUI VI, that displays the data in graphs and charts. The data is transferred betwen the VIs via LV2 globals.
The GUI VI is a bit more complicated than I first mentioned. It has tab control, with 4 waveform charts on one page, 4 waveform graphs on another page, and 3 waveform graphs on another page. The charts have a history length of 2560, and 16 data points are added 16 times a second. The wavefom graphs are only updated once per minute.
I don't use the value property at all, but I do use lots of property nodes for changing the properties of the graphs and charts e.g. changing plot colours, Y scale range etc. There is only one local variable (for the Tab control). All the graphs and charts have data wired directly to their terminals.
I haven't done any profiling yet.
I am building arrays in uninitialised shift registers, but this is all well under control. As the experiement goes on, more data is collected and stored, and so the memory usage does gradually increase, but only to the extent that I would expect.
The CPU usage is 100%, but I thought this was always the case when using NIDAQ with DAQ cards. Or am I wrong about this? (As a side note, I am using NIDAQ traditional, but would NIDAQmx be better?)
Execution priority of the GUI vi (and all the other VIs for that matter) is set to normal.
The program is a bit large to post here, and I'm not sure if my company would be happy for me to publicise it anyway, so I suspect that this is turning into one of those questions that are going to be impossible to answer.
Just as a more general question, why would turning off multi-threading improve the user interface response?
Thanks,
Mark.

Mac system, When I use shockwave, the response time is very slow. I have updated Shockwave.

I am running OS X 10.6.8. I am trying to do a jigsaw puzzle, but the cursor movement is slow and erratic. I have updated Adobe Shockwave, but still have the problem. The last time I updated Firefox I had the same problem and went back to the old version. Any help would be greatly appreciated.

Slow response times

This last weekend, we migrated off of our old server 2003 cf7mx server, to a new Server 2008r2 x64 CF 9,0,1,274733 server. We are now experiencing slow response times for our server,according to the Windows Performance monitor our Avg Request times are way up. I have been going through some logs but nothing seems to leap out at me, but i am not the best CF admin. As i dont know what information would be usefull, i have tried to give all the info.

Please let me know if any other data would be usefull.

Hi,
I expect the error details in CF9\runtime\logs\coldfusion-out.log will like provide a clue as to problem.
For a more long term plan I think you should do what you can to migrate the ACCESS data to SQL or some other database.
HTH, Carl.

Response time increase in OSB

Dear all,
While performing the Load test, during initial 2 - 3 hrs performance is very good. after 2 -3 hrs response time increasing and there by throughput going down 4 times.
when i check in GC Log, i found all OC's. generally i used to find many YC's and very less OC's. but this time its deferent. not sure why this behaviour.
Below is snap shot of my gc.log.
Following are my startManagedweblogic java options.
JAVA_OPTIONS="${JAVA_OPTIONS} -Xverbose:memory -Xmx:6144m -Xms:6144m -Xns:3072m -Xverbosetimestamp -Xgcprio:pausetime -Xverboselog:/usr/home/WEBADM/blq2gsbl/BLQRYSBDM/bin/gc.log -Xverbose:gcreport -XlargePages -XXgcThreads:8 -XXtlasize:min=2k,preferred=16k -XXnoSystemGC"
please note that i have enough memory to increase till 12 gb also. i found better performance with 6g so i kept it as 6.

You need to find out the error code you get in fault due to response timeout. (run a test using test console and you would get that)
In error handler of stage from where you are calling this business service, check whether status code in $fault is equal to the error code due to response timeout. If it is equal then replace content of $body with required error xml and use reply with success.
See section "37.6 Fault Variable" to know more about $fault -

Response time in web services

I have a simple calculator web service running on tomcat server. On the client side, I have a loop in which I randomly select 2 operators and an operand and invoke the calculator web service.
I was conducting tests by invoking the web service within a loop. I observed that as the number of requests increased the response time reduced. I am unable to figure out why this happens.
Any help would be appreciated.

For monitoring BPEL orchestrated services (process status, activity, variables, suspend/resume/terminate instances), we have open source bpel monitor API and command line tool.

JCShell command response time in miliseconds

Hi,
Is there anyway to capture milliseconds response time in JCShell?
I'ved looked at the "time" variable, but it does not seem to have a milliseconds format.
Thank you for any help.

Thanks for your reply. So, I gather there is no way to capture miliseconds from the JCShell.
I wonder if a plug-in would do the trip? I am new to JCOP. Could a plugin give me the system time in milliseconds?

Response Time of MSON Application

Hello SDN Users,
we want to use the Mobile Sales Online for CRM (MSON) Application for our Sales Representatives. Currently I'm testing it on a BlackBerry 7230 with a T-Mobile Germany connection. On the location I'm testing the antenna indicates 2 active bars. The BlackBerry Browser is in the default setting. I've started the MSON Application and stopped the time between Get link of "My Activities" and the display of the Search Form. The time was 15 seconds. I think this will not be accepted by our users. I've also tested this with the BlackBerry Device simulator on my local PC connecting directly to the Portal server where the Mobile Sales application is
running. The time was 4 seconds. Some other pages I've tested:
Search to Result list:
BlackBerry 10 sec
Simulator 2 sec
Result list to Details
BlackBerry 9 sec
Simulator 2 sec
Questions:
1. Are they any suggestions to reduce the Response Time of this application?
2. Has anyone else implemented MSON in real world enviroments?
3. What where the response times?
Best regards
Gregor Wolf

Hello Gregor,
There are numerous factors that effect the performance of the MSOn application like data volume and the landscape of the WebAS and CRM backend. In this application the WebAS makes intensive call to the CRM backend, its very important to have the WebAS and the CRM backend close together in order to reduce the network latency. The connection type also has great effect on the application performance.
Also, in addition to the landscape, the data volume could also reduce the response time of the application. In the search forms if some condition is given , instead of blank form the response time is much faster. In the new SR3 version of the application, atleast one search criteria has to be specified.
Due to all such variables its difficult to give concrete figures regarding the testing results within SAP.
Kind Regards

Response time between LabVIEW w/DSC module and RSLinx OPC server hosting FlexLogix PLC tags too long

We are experiencing communication response time delays between LabVIEW with DSC module and RsLinx OPC Server hosting all FlexLogix PLC tags (around 500-600 tags).
The nominal response time for the system watchdog is < 500ms, but we occasionally have spikes of up to 1.5 seconds once every few days even when the system is idling.
Changing more than six PLC connected shared variables at the same time from LabVIEW also causes the watchdog response times to spike above 500ms.
Our watchdog is programmed so that LabVIEW toggles the watchdog bit to 1 as soon the shared variable event detects that the PLC has toggled it to 0. The PLC, however, waits 300 ms until it toggles it.
Our system:
Windows XP SP3
LabVIEW 9 F3
RSLinx Opc Server v2.54
Allen Bradley FlexLogix PLC

What is your update rate set for in the RSLink OPC server?
You aren't toggling the same flag from both ends are you?

Unable to capture the Citrix network response time using OATS Load testing.

Unable to capture the Citrix network response time using OATS Load testing. Here is the scenario " in our project users logs into Citrix network and select the Hyperion application and does the Transaction and the Clients wants us to simulate the same scenario for load testing. We have scripted starting from Citrix Login and then launching Hyperion application. But the time taken to launch the Hyperion Application from Citrix network has not been captured whereas Hyperion Transaction time have been recorded. Can any help to resolve this issue ASAP?

SAP GoLive : File System Response Times and Online Redologs design

Hello,
A SAP Going Live Verification session has just been performed on our SAP Production environnement.
SAP ECC6
Oracle 10.2.0.2
Solaris 10
As usual, we received database configuration instructions, but I'm a little bit skeptical about two of them :
1/
We have been told that our file system read response times "do not meet the standard requirements"
The following datafile has ben considered having a too high average read time per block.
File name -Blocks read - Avg. read time (ms) -Total read time per datafile (ms)
/oracle/PMA/sapdata5/sr3700_10/sr3700.data10 67534 23 1553282
I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
2/
We have been asked to increase the size of the online redo logs which are already quite large (54Mb).
Actually we have BW loading that generates "Chekpoint not comlete" message every night.
I've read in sap note 79341 that :
"The disadvantage of big redo log files is the lower checkpoint frequency and the longer time Oracle needs for an instance recovery."
Frankly, I have problems undertanding this sentence.
Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right ?
But how is it that frequent chekpoints should decrease the time necessary for recovery ?
Thank you.
Any useful help would be appreciated.

Hello
>> I'm surprised that an average read time of 23ms is considered a high value. What are exactly those "standard requirements" ?
The recommended ("standard") values are published at the end of sapnote #322896.
23 ms seems really a little bit high to me - for example we have round about 4 to 6 ms on our productive system (with SAN storage).
>> Frequent checkpoints means more redo log file switches, means more archive redo log files generated. right?
Correct.
>> But how is it that frequent chekpoints should decrease the time necessary for recovery ?
A checkpoint is occured on every logswitch (of the online redologfiles). On a checkpoint event the following 3 things are happening in an oracle database:
Every dirty block in the buffer cache is written down to the datafiles
The latest SCN is written (updated) into the datafile header
The latest SCN is also written to the controlfiles
If your redologfiles are larger ... checkpoints are not happening so often and in this case the dirty buffers are not written down to the datafiles (in the case of no free space in the buffer cache is needed). So if your instance crashes you need to apply more redologs to the datafiles to be in a consistent state (roll forward). If you have smaller redologfiles more log switches are occured and so the SCNs in the data file headers (and the corresponding data) are closer to the newest SCN -> ergo the recovery is faster.
But this concept does not really fit the reality because of oracle implements some algorithm to reduce the workload for the DBWR in the case of a checkpoint.
There are also several parameters (depends on the oracle version) which control that a required recovery time is kept. (for example FAST_START_MTTR_TARGET)

After IOS 8 update, the screen is jerky and the response time is really, really slow... Using a PC to submit this!

Is there a solution to a jerky screen and a slow response time after updating to IOS 8?

Try some basic troubleshooting:
(A) Try reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
(B) Try reset all settings
Settings>General>Reset>Reset All Settings
(C) Setup as new (data will be lost)
Settings>General>Reset>Erase all content and settings
