Executable jars are running slow for certain features
A weird problem occured one day. I started running my old jar -packed application. It took more than a minute to load the main window. Also updating file browser window is really slow when I browse from a folder to another. I also tested running other jar applications and they have similar problems. Everything works but certain task are extremely slow.
I reinstalled jre1.6.0_07 but it did not help. Then I uninstalled all jdk's and jre's and installed jdk1.6.0_07 which came with jre1.6.0_07. No result. Do you have any idea where the problem is or what I could try next?
Problem solved.
It was the mingw that I installed as full installation. Full installation came with a java compiler, which made some specific java features really slow.
Another problem was uninstalling it in a way that would have restored java as it was. I tried uninstalling mingw, manually removing mingw folder, cleared environment variables, removed and reinstalled all java etc. Finally, I just reinstalled everything beginning from OS on my computer

2.2 is slower - for certain types of processing
So far the only major complaint I have with 2.2 is that it's slower for certain things. Scrolling through pictures in the camera app is slower. With 2.1 the pictures would show up immediately even when scrolling through them very fast. Also the grid view would load much faster, now i see a blank gray picture for 3-5 seconds before the actual photo loads. Scrolling through my contact list and app list is slower and choppy. Before it was fast and smooth.
Has anyone else noticed these types of issues? Could the amount of processes running in the background cause the "jitter" during processor intensive usage? With 2.1 I had the bare minimum running in background - maybe 2 - 4 processes and never had any issues. Now, I've disabled ATK - which seemed to help battery life, because of the wonderful programs that auto-restart themselves (such as Amazon MP3, footprints, skype, VZ Navigator, FM Radio, etc...), and have 10-20 processes at most times.w40d1n1 wrote:
I believe that the froyo sluggishness, of the browser (pgup/down while the browser is still loading images), image viewer, and contacts, is due to the new "keep everything running in memory, and we'll sort it all out (by consuming more cpu) when the resources get low and froyo has to start killing/swapping apps to make room for the current app you are using" theory.;-)
actually it requires less CPU power to do it the Android way. It requires more processes force closing apps then then openning up what you want. Once a application is in memory it has 0 processes unless you are using it. If it uses a process then it is collecting data, or doing something you want it to do.
Everytime someone say Task Killers are needed still can't differenciate between process and application under the terms of Linux. I really do find it funny though. You NEVER hear people stating you need a Task Killer for OSX, Ubuntu, Fedora, or <insert linux variant here>, but always recommend it for Android eventhough it is a Linux Variant itself. -
Adobe Creative Cloud - has anybody had any luck running Adobe CC on a new mac mini? Does it run slow for Photoshop?
Adobe CC applications are very large and the base Mac mini isn't a good choice because it has only 4GB of RAM and has a slow standard hard drive. To get the most out of ACC you should upgrade the mini to at least 8GB. I'd also choose an SSD or Fusion drive for better performance.

Fetching queries that are running slow
Hi all,
Is there any tool in Oracle 9i, by which we can fetch queries that are running slow in the entire database on a weekly basis ?As mentioned, the statspack tables and the shared pool views from which they take their snapshots - V$SQL / V$SQLAREA - provided various ways for you to idenitify top N statements by cpu time, elapsed time, logical io, physical io, etc.
For a weekly basis, the statspack tables and statspack reports provided the easiest way to do this, a) providing you're capturing this data and b) depending on how long you're retaining it. -
I have an early 2011 MacBook Pro which has been running slow for a while. After looking at responses to similar problems I have downloaded and run EtreCheck. Please can someone help me with what it all means.
Thanks in advance.

My macbook pro has been running slow for quite some time
Hello, my MacBook Pro has been running slow for quite some time now and it's frustrating. I hope you'll be able to help me. I've read this thread and figured out I should open a new one, so here it is.
I've already downloaded Etrechech and ran it and this is what I got:

Ever since I updated my ipad2 and iphone5 to ios8, both devices are running slow, apps take forever to download (Google is STILL downloading on both), and they freeze/crash. This is VERY frustrating! Anyone else having the same problems?
Message was edited by: RkksheaHad same problem on my iPad2 with the original 8.0 release. I ended up wiping it completely clean and doing a reset and restore from backup. That seemed to fix my issues. I had the same problem when 7 came out and did the same wipe and restore to get everything working well.

i am trying to detect signal peaks (derivatives of the peaks both +ve and -ve peaks). simultaneously 2 peaks detectors are running, 1 for +ve and other for -ve peaks. when a peaks get detected it would trigger a pulse of approx 1 sec duration and at the same time it would disable the other peak detector for 1 sec time duration. after the time period, again both the peak detectors would be enabled. i have been able to detect both peaks but still not able to control the detectors block the way mentioned before.
the code and the data are attached.
Attachments:
eog peak detection.vi 192 KBI'm not suggesting any of this as a model, and your needs are different than mine.
1) Go to Preferences -> Audio. Under "Default Audio Tracks", Set "Mono Media: Mono". Set "Stereo Media: Mono" (Choices from the pull-down for both are Use File, Mono, Stereo, 5.1, Adaptive)
You can change these, but I don't. I am using both mono and stereo tracks. I set up a custom sequence with the particular combination of stereo and mono tracks I want.
2) Set audio for clips by selecting all clips and going to Modify Clip -> Audio Channels Tab. Under "Number of Audio Tracks" there should be a "1". Under Channel Format it should read "Stereo".
I am not sending the audio to anyone else to edit further. I am doing a final stereo mix. If camera one is set up to record 2 mikes as a stereo track, then I leave that unchanged and put it onto a stereo track. If camera two is set up to record one mike onto channel 1 as ambient sound and channel 2 is a mono feed from a sound board, then I modify those clips as Preset Mono, 2 audio tracks, Channel format Mono, and that puts the left source channel (or whichever I choose) onto Audio track 1, channel 1 (of one), and right source channel onto audio track 2, channel 1.
4) Delete all the existing audio tracks in the sequence and replace them all with mono tracks, so all tracks in the sequence are mono.
I modify the tracks while creating the sequence, and ultimately use a custom sequence.
Under my Effects Controls panel there is only Channel Volume, and nowhere to adjust the pan.
I'm using the mixer, not the effects control panel. -
Hi,
The issue is, a process, say "A" is running fine on certain days. On some days there are additional processes running on the server. When these additional processes are running, "Process A" suffers performance issue.
Interesting point is that, these additional processes were running since long time. But, earlier "Process A" was running fine even when these additional process were running. Suddenly from past 2 or 3 weeks there is performance issue in "Process
A", when these additional process run.
Note: Nothing has been modified for the process A.
Process A is an SQL job which has SSIS Package and stored proc in different steps
When multiple parallel processes are running, SSIS Package step suffers around 40% increase in execution time, where as stored procs have only 15-20% increase in execution time
When Process A is executed while no other big processes are running, it's execution time is fine. From past few days, issue is only when, some other big parallel processes are running.
Currently below is my analysis:
Since Process A is running fine when it is executed independently, I assume there is no issue in this process.
Since issue occurs when some other big process is running, when Process A is running, I believe it is DiskIO issue. Will the issue be resolved if RAM size is increased?
Is there any way to check if RAM is being fully utilized by the server
Is there any other possibility why there is a sudden dip in performance when parallel processes are running.
Is there any possibility of having issues in additional processes. Incase if it has some issues, does it impact "Process A"
Please let me know if you need any further information. Infact I am not able to diagnose what is the actual root cause for the performance issue in "Process A" as nothing has been modified.
Also it would be very much helpful, if I get any idea on different ways in reaching the actual root cause of this performance issue.
NOTE: This is a data warehouse
Thanks,
RakshaWhen a query has a parallel plan, it will in general try to grab all cores up to the maxdop setting, but then it often uses them inefficiently.
But in that case, there are better odds for the queries not battling on resources with each other!
What Josh alludes is to the fact that SQL Server needs to partition the data, so that different partitions are processed on different cores. This partitioning is based on statistics, and the statistics may be out of date or not accurate enough. This may
result in that the data is not partitioned proportionally, and some threads gets very little data to work with. Thus, these CPUs are still idle, so there may still be room for the two processes to run at full speed. (That is, full speed with the given plan,
which is not the full speed, had the partitioning been accurate.)
I mention this because you asked about parallelism, and many systems leave maxdop at its default setting of 0 (which means "go ahead and grab everything!") even though Microsoft recommends you set it to a different number depending on this and
that.
Since this is a data warehouse, Raksha should not tamper with "max degrees of parallelism", I think.

Hi Gurus,
This may be repeated question but I didn't find suitable answer and need your help.
There are number of webi reports which is based on olap connection directly on bex query. We are experiencing the slowness while opening the report and even opening for selection screen for prompts.
This is happening from past few days.
There is slight slowness in backend BI system as well.
All the BO servers are running fine.
BO Version: BO 4.0 sp6.6
Thanks & Regards,
Harsh WardhanSometime the cache got fill , restart the servers once and it should be as before.

WRT54GS running slow for 1 month for no apparent reason
Hi guys,
It's my first post here and I've read a few hints regarding slow wireless connections however I seem to have exhausted my alternatives to fix the problem.
My scenario:
- 1 Orange Wanadoo Livebox ADSL modem/router
- 1 WRT54GS wireless router
- my laptop (only user in the network)
So I have my livebox router configured to IP 192.168.1.1. From the yellow port, an ethernet cable connects to LAN (not the WAN) port of the WRT54GS. This router is configured with "automatic configuration - DHCP" and local IP 192.168.1.2 and internal DHCP server is disabled (since the livebox is already providing a DHCP server). It's running in Gateway mode. I understand this configuration essentially makes the WRT54GS an access point. I opted for this configuration so I don't need to have 2 networks, one for the orange modem/router and another one for the linksys, leading me to added complexity and double NAT port forwarding configuration..
I've been using it happily like this for a while, however 1 month ago the internet slowed down considerably. I run Network stumbler to make sure that I'm the only one using my channel, which I am. Also, there's no close channel numbers with a strong signal nearby.
Yesterday I decided to connect my laptop wired to the livebox modem/router. Running a download test I achieved consistently 750 Mbytes/s download. When I use my laptop wireless (through the linksys) I get max 350 Mbytes/s with some drop-outs that make it to a low of 25 Kbytes/s. The wireless connection also seems to break easily. I was running the wireless test with my laptop basically next to the linksys. Bluetooth was turned off, my phone was off and I have not acquired any new radio-waved devices lately.
So I don't know what else to do... could it be that the linksys actually has a problem with it ? I didn't try connecting wired to the linksys with my laptop because I need another ethernet cable, but the wireless definitely seems to have run kaput. Also, I tried to run the linksys web ping tool but for some reason it cannot ping my livebox 192.168.1.1 neither resolve domain names (?)
350 Kbytes/s doesn't seem like a bad thing, however it's half of what I get wired not to mention that the QoS also decreases a lot... I get terrible lags with regular internet browsing, sometimes only fixed by a refresh to the page I'm currently browsing.
Any hints appreciatedI assume that you mean that when you wired your computer to your router, or directly to your modem, that you got 750 kbytes/sec , and then wirelessly you got only 350 kbytes/sec. Is that correct?
Wireless connections require more overhead, so wireless speed is usually 50% to 70% of wired speed. You are running at 47% and lower, so it does sound like you are having a problem.
Are you running any peer-to-peer (P2P) software? If so, this is a known cause for router slowdowns and disconnections. The problems can occur even if the P2P software is not currently running on your computer. If you are running P2P software, stop using it. It can take up to 5 days for the router to clear its memory and work properly again.
After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, please do this now and see if it corrects your problem. If you saved a router configuration file, DO NOT use it.
If the above do not correct your problem, then the next most common cause for this is simply poor wireless connections. Note that you can have a poor wireless connection even if your computer shows "5 bars".
There are many causes for poor wireless connections, and many solutions:
In the router, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your wireless card.
Some users have reported improved wireless performance by switching to WPA encryption.
If you continue to have problems, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps. -
My MacBook Pro running slow-for everything
Hello everyone!
I am fairly new to the MacBook family. Just got my very first one last year for Christmas. It has been wonderful and I'm sure I'm not using it to its fullest potential. It hasn't given me a problem at all for an entire year until just about a week ago. Its running slow. Stagnant in fact. It takes forever to even boot up. I see the color wheel for everything that I try to click. Safari, Mail, etc. Even if I just want to shut down or restart. It seems to freeze on everything. And there was no warning to it. One day working fine and running at its usual lighting speed and the next day color wheel for everything.
I'm sure its new operator error and would love any suggestions on how to fix it (or what I am doing wrong) before I make an appointment to go talk to someone at our local Apple store.
Thanks in advance for all your help!How large is your hard drive and how much hard drive space do you have left?
It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.

Create executable jar and run it
hi ,
I want to create an executable jar file for my Swing application in windows environment and I want to run that jar file by double clicking on it. What should I do?I can't beleive I'm saying this given that I didn't like it only 3 months ago but if you change your development environment to Eclipse rather than JCreator/JBuilder or whatever, it saves all that creating manifest files by having one menu item, "Export". You should take a look at minifest files though and at least understand them, they aren't complex at all.

I have not upgraded to CS3 but from many posts in this forum
it sounds like CS3 should just not have
been released for the Mac until it was ready.
Folks with Macs seems to share the same experience of CS3
beeing very slow to the point of not being
usable.
Just stick to version 8, and wait for an update that might
solve these problems... If it ever comes.
