Horrible performance (downloading not w/ Torrents)

This applies to both torrents and non-torrents.
I can get a perfect connection without modifying any settings in my previously used Linksys router (pretty much similar set up with the AEBSn didnt set any port mapping or anything other than let it do itself from the modem. and it was wired)
Connected via the ethernet using OSX and XP on my macpro with the AEBSn i was attempting to receive a large file and it seems like it cuts out the rest of the bandwidth however when attempting to do it with the other router i can download that file at proper full speeds and still pages load fully instead of half or none at all with the AEBSn
using speedtest.net my results for the other router (linksys) compared to the AEBSn
Linksys: 11452kb/s Download // 2518 kb/s Upload
AEBSn: 5892 kb/s Download // 2343 kb/s Upload
so the upload is usually not bad but the download rates. Im not sharing any sort of connection via my computer
here are screen shots of the settings in my AEBSn for further looking:

thanks!

just thought id add that even without downloading anything it seems like somewhere in the connection there is some sort of configuration where its making all the connections share one speed/transfer rate, as without downloading anything on my end pages dont fully load. iget random have pages =/

Horrible Performance On Good Hardware + Usability Questions

I downloaded the most recent iTunes version as of 1 week ago, to use to sync and backup my iPhone.
I have a few complaints: Horrible performance. Clicking on just about any node, and it takes 5-10 seconds to load whatever window it is calling. Navigation from any menu to another is just a disaster. My PC is XP Pro with 4 GB installed RAM, an Intel 3 GHZ processor, and a 10,000 RPM hard drive and solid mid range gaming video card. All other applications work very quickly.
Second, is there a decent way to search the App Store? From my phone I can easily search on a key word, but in iTunes the advanced search doesn't seem to just search apps, it searches all. I figure I MUST be missing something!
Thanks!

It's a long shot, but you might try temporarily disabling any antivirus and antispyware applications you may have on your system, including Windows Defender if you installed it, and see if that makes any difference. I've encountered situations, albeit rare, where such a utility gets "overzealous" and starts scanning every activity for an app, thereby slowing it down. You probably want to disconnect from the Internet while you make such tests just to help ensure nothing sneaks onto your system.
If that doesn't help, you might try completely removing and reinstalling QuickTime and iTunes. Instructions can be found here:
Bugie: Perform a Thorough & Complete Uninstall and Reinstall of iTunes/QuickTime.
Make sure you make a backup of any content you've purchased from the iTunes Store or that would otherwise be difficult to replace, just in case something goes wrong.
Not much positive help, I know, but perhaps it might do some good.
Regards.

Another "horrible performance after upgrading to Lion" post

Hi,
Sorry for yet another "my computer has horrible performance after upgrading to Lion" post. I did search the forum before posting.
I have a relatively new Macbook Pro, 8 GB RAM, 2.8 MHz Intel i7 CPU. I upgraded from Snow Leopard to Lion, then Lion to 10.7.2.
The first time I upgraded, I no longer had my user account, so restored from Time Machine back to SL. After a month or so, I hoped Apple had fixed the bug, so I redownloaded and reinstalled, and this time the upgrade succeeded.
Ever since the upgrade, my MBP runs like a dog. I get the spinning beach ball constantly, across all range of applications, both Apple and 3rd party. Occasionally it doesn't wake up from sleep (close, open lid) and I have to kick it in the head by holding down the power button.
I've tried booting into the recovery partition, running disk utility, and repairing disk and permissions. I've read elsewhere (Google hit) that doing a completely clean install fixes the performance issues (for those users anyway).
I know this is a fairly generic post, but any advice on how to maximize machine performance under Lion, or should I revert to Snow Leopard? Do I really have to wipe the disk, install fresh, restore all non-OS files (don't accidentally wipe a required OS file), then reapply the 10.7.2 maintenance? Yuck.
Thanks,
Scott

try an SMC reset if you are not seeing any weird spikes in Activity Monitor and you've deduced that none of your third party drivers or apps are interfearing with the way lion works.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Anyone using a 12 Core Mac Pro? I have HORRIBLE performance issues .. Help!

After the latest 10.7.4 Mac OS X update I have extremely horrible performance issues with AE ... and they were not so great before the update.
It is still stabilizing ... but an 1:19 clip in SD is taking 12 HOURS TO analyze and stabilize. !!!
The 12 cores are barely being used and this problem has been an issue since I purchased the suite over a year ago.
Does anyone else have problems using AE on their 12 CORE MAC PRO?
REPLY ONLY IF YOU HAVE A 12 CORE MAC PRO PLEASE.
There must be a problem because since the update ... Adobe Encore is PERFECT .. and ALL 12 CORES MAX OUT and the encoding is quick!!
I also have major problems between PP and AE using Dynamic link .. and slow renders in PP.
Everything else works fine .. other apps / other vendors.
I am calling Adobe today.

Thank you for your time.

Only half of my hyperthreaded processors are active when using AE "Warp Stabilizer". This issue was addressed before in the Forums. There was no solution. I dont' know if it is any better in CS 6.
Also the automatic saving of all linked compositions while using the dynamic link feature bewteen PP and AE causes huge inoperatable waiting times .. unbearable. My guess is that the new "Global Performance Cache " fixes this ... which I consider update to a terrible problem .. but they sell it as a feature ( Ill go into that later.
Question:
What RAID card are you using?
Do you use the Warp Stabilizer?

I tried to restore my ipod touch because i forgot the password, but computer says download not complete. How do I get my ipod to work?

My computer will not let me restore my i pod touch. My daughter forgot the password and we have not been able to use it. Someone told me to restore it, I tried and the computer looks like it is downloading for a couple of minutes but then says download not complete.

CS6 Photo Downloader not functioning correctly.

CS6 Photo Downloader locks up when I attempt to download photos. Buttons like browse, settings, get media do function. This worked fine with CS5 Bridge on this machine. The machine is a windows 7 box.
I had CS5 Master Suite side X side installed with CS 6 Master Suite. When I noticed problems with the CS 6 Photo Downloader not working correctly I uninstalled CS5 Master Suite. This did not resolve the issue and I am stuck with lots of photos that are unable to be downloaded using CS6 Photo Downloader.
Any ideas?

Hi. This forum is for beginners trying to learn the basics of Photoshop. I'm moving your question to the Photoshop General Discussion forum for specialized attention to your situation.

JSF 1.2 performance is not adequate

Sun JSF developers...
JSF 1.2 performance is not adequate.
Here is a simple use case to prove:
Render a table with ~100 columns and ~1000 rows (with facelets)
(you could increase the numbers to stress test)
using h:dataTable tag.
You have to repeat h:column hundred times in XHTML (to create bigger
UI component tree).
Have a backing bean with 100 properties and JSF action which returns
list of 1000 those beans.
In this case there is no DB interaction, no back-end involved.
Have your application set up with Ajax4Jsf (so it goes via its filter). You could
also compare the results with and without it.
Measure RENDER RESPONSE phase, and overall response time.
Compare with JSP which renders same table from same bean.
This is very simple test case to write and you will see that JSF in current state is really slow.
This test could also be used to measure performance of new versions to see where they stand.
It would be also interesting to see how render time grows with increase of
number of columns (number of components in UI tree) (Is it linear or not?)
How fast does it grow with the number of rows (Is it linear growth with increase of data size?)
I believe this type of tests should be standardized before each release.
Does JSF development team perform regular profiling of JSF RI java code?
Running profiling for this use case could also reveal interesting things which
could be improved.
Regards,
--MG

But you have done nothing here to determine if itscales linearly or not.
See below.
You increase number of columns (rows) and measure
time.
When you draw on a chart how time grows with increase
in number of columns (rows) you will see if it linear
or not.
I understand how to determine the growth rate; I was merely pointing out that you have only claimed to run one test and one cannot determine the growth rate from that.
It would be also interesting to see how render timegrows with increase of
number of columns (number of components in UI tree)(Is it linear or not?)
How fast does it grow with the number of rows (Isit linear growth with increase of data size?)
Unless you are talking about spreadsheets I doubtthese apps are useful.
They are very useful.I bet they would be more useful as native desktop apps.
>
But this is besides the point; my point is that thescenario of having a large number of components on a
page does not occur often in real applications.
Really? You are not serious?Yes I am serious. I can see we have different perspectives here.
>
A much more common performance scenario is highload.
This is separate story. I'm talking about latency of
loading one page.
Please do not confuse latency and bandwidth.I am not talking about bandwidth but throughput.
>
BTW most of the web sites have small number of
concurrent users,
so the most common scenario is actually exactly
opposite.
Low load but complex pages with lots of components on
them.Again, I can see we have different perspectives here. My experiences are the opposite.
>
So your results will be much more useful if youinclude a load test on a moderately sized page. I'm
not dismissing your original test as invalid or
useless.
My results are more useful than what you are
proposing, as they help to pinpoint the cause of
latency. You could run my test with profiler and
investigate the root cause of it.You do not need to increase the number of components on the page to numbers beyond practice in order to determine this. It is sufficient to run profilers on average pages many times and determine where the most time is spent. In fact, your approach may result in an implementation optimized for pages with a large number of components but not for pages with a lower number of components.
>
My point is that the user experience is not degradedby the performance but by the poor presentation of
information. Many web browsers to not take kindly to
such large tables as well.
With JSF user experience is degraded by performance.I'd like to see your numbers and the code you used.
JSF makes it easier
to do nicer user presentation, but performance
suffers to degree that it is not usable in number of
cases.
JSF inability to generate page fast on server side
has nothing to do with browsers.Correct; but I was talking about pages with large tables in general and why they are a bad idea for web applications. A native application is more appropriate. But this is orthogonal to the purpose of this thread.
>
Again, you are missing the point. Perhaps JSFperformance differs between the application servers.
A fair and useful test will determine that. I'm not
talking about the relative performance vs JSP here.
If JSF does things inefficiently in its code it will
show consistently bad results
across all app servers. Again my test is to detect
and pinpoint JSF inefficiencies and not app servers
ones.
Don't you think JSF developers would want to look for
it first rather than investigating why it perform
badly on some particular app server because of
its internal reasons.I'm approaching this from the perspective of a developer evaluating whether to use JSF and which application server to use. This is very useful from this point of view.
As far as the JSF developers go, as I noted above one does not need to scale out the number of components on the page to determine performance bottlenecks in the implementation. An average case is more appropriate.
Also, if you are going to compare JSF to other technologies you need to try a variety of platforms for both. Some application servers might do JSP better than others. If you limit yourself to one platform you run the risk that it is skewing the comparison one way or another.

Thank you in anticipation.

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.

Performance Analysis Notes

Hi,
I want some "Performance Analysis Notes or material"..
Plz give me some links or send me on my id: [email protected]
Thanks...

Hi, this may help you.
1) Dont use nested select statements
2) If possible use for all entries in addition
3) In the where addition make sure you give all the primary key
4) Use Index for the selection criteria.
5) You can also use inner joins
6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
ABAP performance depends upon various factors and in devicded in three parts:
1. Database
2. ABAP
3. System
Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
u can get an interactive grap in SE30 regarding this with a file.
also if u find runtime of parts of codes then use :
Switch on RTA Dynamically within ABAP Code
*To turn runtim analysis on within ABAP code insert the following code
SET RUN TIME ANALYZER ON.
*To turn runtim analysis off within ABAP code insert the following code
SET RUN TIME ANALYZER OFF.
Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
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.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
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.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT
