Why EP is very slow just after it is started?

Hi, all.
Our env is like the following.
EP 7.0(NW 2004s).
But i think this also applies to NW 2004.
Just after EP is started, when the first user logs on, EP is very very slow
(takes long time while logging on and navigating) and its server CPU goes 100%
for a while. Why?
This phenomena is very similar to the situation that usual JSP web pages are
slow at first because it has to be compiled. Does EP have the same reason?
1. Could someone teach me what would be the possible reason?
2. Is there any way to avoid this phenomena? Like precompiling or something
like that.
Best Regards.

Hi Sejoon,
To add to answers above - When a user logs in , in addition to login time and services/components are loaded into memory, also first time navigation takes time. This is to load the entry points (in TLN and first level DTN). These entry points are loaded into navigation cache (if not there yet). if indeed it takes too much time to load these navigation entries and its a problem , you can consider using the navigation cache preloader:
see http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0f1358d-0812-2c10-b58c-c7bdd7a0cdce?QuickLink=index&overridelayout=true&42477226648018
and http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0f1358d-0812-2c10-b58c-c7bdd7a0cdce?QuickLink=index&overridelayout=true&42477226648018#page=30&zoom=100,0,842
It will upload all of the roles of a specified user into the navigation cache.
Best Regards,
Tal

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

I am using ipod touch 4g 8 gb, with ios6 software. It is getting very very slow even after i reinstalled the software. Apps like temple run 2 and subway surfers are getting stuck and it is very very slow.My ipod has 2.6 gb free space. What is the problem. I am not getting to know. Even after i reinstalled these apps it is still getting stuck and it is very very slow. Is this what i get after paying so much money for ipod. Is this what i get very poor perfomance.

Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
Next
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:

Very slow Safari after IOS8 Iphone 5S

Hello all
I live in Iraq, so basically internet here is very slow, however after installing IOS 8, Safari now is very very slow
I tried other browsers and they were a better
any one of you guys have similar issue ?

My iPad and iMac are really screaming after the update. My iPhone 4 is running more slowly. What's odd is that even with it right next to the AEBS it's running slow. The iPhone 4 is listed as 802.11 b/g/n in Airport Utility in the Advanced/Wireless Clients window. When it was running slow, the signal level was OK (actually good-about the same level as the iMac) but the noise was high so the signal to noise ratio was only between 12 and 20 dB. Also the rate was at 5 and staying there 9 (not sure what the rate number is but it was much smaller than all the others clients).
I turned WiFi OFF on the phone then back on again. When it came back, the signal to noise ratio was better (went to about 30-40 dB, and the rate went up to 58. Then after a few minutes, the signal to noise ratio went back to about 20 and the rate number dropped to 5 again.
I'm not sure what this all telling me exactly, but I agree the iPhone seems a bit slower. It's running quite a bit below my 60 day average for download and uplaod speeds - especially a ways away from the AEBS (new 5th gen). The other devices (iMac and iPad are performing as good and even a little better than their 60 day averages.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

Why aperture running very slow?

I just installed additional ram and the other day aperture was running extremely slow. The only other application was iphoto.
How much CPU power does aperture require?
thanks.

After consolidating iPhoto pictures into Aperture Library - and having to rebuild library all photos are shown under "Other" in storage under About this Mac. How do I get photos back into the Photo section. I am sure this is why Aperture is running very slow. Aperture library is on a 500 GB external USB hard drive. Does anyone know how to get photos into the right spot in the storage.
Nothing in my experience would make me draw the same conclusion (that the reporting of your Aperture Library as "Other" is why Aperture is running slowly). You report that your Library is on an external drive connected via USB. Is this USB 2 or USB 3?
The consensus is to put your Library on your fastest (lowest latency and highest throughput) drive. This is almost always your system drive. If your Library does not fit on your system drive, you are advised to move some or all of your Images' Master from the Library to a second drive using "File→Relocate Masters". If you want help with these set-ups, post back.

Mid-2010 27" iMac very slow, even after clean OS install - HELP!

Good afternoon guys, I'm hoping someone can offer me some advice.
I bought my Mid-2010 27" iMac in May-ish 2011. Everything was brilliant, I couldn't believe the ease of use, and especially the start up speed, coming from a world of PCs. My iMac was used almost every day, for web browsing, photo editing, etc.
Maybe about April / May this year it started becoming very slow, slow to boot, slow to respond to mouse clicks, slow to do anything. Since I'd used about 750GB of my HDD (mainly photos), I decided I would archive some and hope that would ease the congestion. As my photos were stored in Aperture, it took about 3 days to export them all to my external HDD, 3 days of the iMac only getting so far, switching itself off, then me finally getting it to come back on (I was getting messages about Kernals, etc. now and again through boot too) - it finally backed up my photos I have from my daughters first year.
Great news, but I still had probably 400GB / 500GB of photos from her second year and any other photos I'd taken. I found the root of my Aperture directory, and managed to pull these images off, so everything is now backed up.
I decided I should try and clean install, and managed to get the HDD to boot and choose the option to re-install from Apple's Servers. All installed OK, and we're good to go! Fired up the iMac, and although it's fractionally quicker to respond, and a lot more stable, it's not quite right. And I've lost all my iLife Apps which originally came with the iMac.
Does this sound like a HDD issue? As I say, it was on quite a lot through the backup procedure, and I had set it (maybe stupidly looking back now) to never sleep, and for the monitor to only switch off after 3 hours. Or does it sound like something more is wrong with it?
I am quite confident of working with PCs, so would manage to replace the HDD I think, looking at some videos, etc. online. I did upgrade the RAM to 16GB, and that was simple enough. My question is, when you replace the HDD, how does it know where to look to the Apple Servers for the clean OS install? Or do I have to do something to let it know where to look first? I have to point out I don't have any Time Machine backup, etc. as the iMac was just not stable enough to get this in place - and up until that point, again probably stupid now looking back, I had never bothered to set up.
Any help / advice on this matter would be greatly appreciated. At the moment I have totally fallen out of love with the iMac, for something to cost £1,500+ and only last 3 years, where my last build PC lasted Approx 8 years for half the price, is very disappointing.
Thanks in advance,
Col

Just suggesting things right off the bat here-
To me it sounds as though the HDD is failing, if your iMac shipped with a Seagate drive try entering your serial number to see if Apple will replace it:http://www.apple.com/au/support/imac-harddrive/
Or try running Apple Hardware Test a few times back to see if it is a hardware error.
As for the iLife apps they should've come on one of the install discs that shipped with your mac.
If your iMac is ineligible for the program above I would consider replacing it yourself with either an SSD or HDD, as for recognising apples servers for download, you will need the original install discs that came with your computer or if you haven't already it will need a firmware update to enable internet recovery
See here:Computers that can be upgraded to use OS X Internet Recovery
Good Luck!

Very slow connection after phone line repair

I had my phone line repaired yesterday with new cabling and new BT box for phone and computer.My phone is fine, but the hub for my broadband does not appear to be ok. the phone symbol on the hub did not light up at all this morning, and after restarting the hub and going back to default settings it is now glowing orange only. It was ok yesterday after being fixed. Very slow connection now. Should i keep everything on to see if it will right itself, or re-start yet again?
I have been looking on BT's options for fixing but can't seem to find anything. the connections in my area are fine so it can't be an outside fault

Which home hub do you have? Did you recently re-contract or change your package, as that will affect your hub phone.
As for the speed issue, it should get better if you leave it alone.

Macbook running very slow - just started, HELP

Hello,
     My MacbookPro just recently started running very slow, even doing simple tasks it runs slow. Was working perfect Sep. 8, 2014. Turned it off for the night, then turned it on the next morning and it took about 5 mins just to even turn on. After it finally turned on EVERYTHING just started running opening the internet, Word, Power Point, and even iTunes was running slow. The songs were literally stopping every 30 seconds. My Mac has worked perfect and all of the sudden BAM. I use it for school all the time so its kind of stressing me out. It keeps freezing up as Itype this message unfortunately.
I ran Etrresoft like most ask here are results:
NOTE** - I deleted Hamchi awhile back, i am unsure how to get rid of it because i don't know where to find it, i thought i had deleted everything.

Start up in safe mode and uninstall or update Hamachi.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

Since download of Firefox Hello desktop & laptop both on Windows 7 are very slow even after refresh, download history removed and anti virus software turned off

Since download of Firefox Hello my home desktop & laptop, both on Windows 7, are very slow to open. I have refreshed firefox, removed download history and turned off the anti virus software in extensions. All the plugins are up to date. Can we revert back to Firefox without Firefox Hello?

Firefox Hello is simply a wrapper for technology already in Firefox, it doesn't negatively impact performance if you aren't using it. Are you saying that your entire computer is slow or just Firefox?

I am having problems with slowness, too - ever since installing the latest Yosemite update I downloaded a few days ago. EVERYTHING - Safari, QuickTime, MS Word for Apple, the DVD Player, everything - runs slowly and I get the "rainbow pinwheel of frustration". It's taken me three minutes to type these few sentences. It's really starting to frustrate me. Here is my EtreCheck report:
Problem description:
Since I installed the latest Yosemite update (10.10.2), EVERYTHING runs slowly. I get the rainbow pinwheel whenever I click on anything on Safari, and have trouble typing via Safari; videos stop and start on QuickTime; MS Word for Apple runs slowly - EVERYTHING seems to be slowed down. It took four minutes to get the above sentences typed. Please help me escape the “rainbow pinwheel of failure”!

Very slow Macbook after updating to Yosemite.

Two questions;
1) I updated to Yosemite a few days ago and like it. But my macbook (2013) is now running very slow. I have done all the latests software updates.
In the Activity Monitor, a process called DesktopServicesHelper (PID 1681) take up 99% of my CPU%. What is this and why? How do I fix it? Please help!
2) Also in the Activity Monitor, there is a process which is not responding, called com.apple.geod (PID 1703). What is this? What does it mean? How do I fix it?

When you have the problem, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.

Why does Firefox performance slow down after starting Jack server?

Hello,
I started configuring my audio on my system. So, I want to have jack working (not jack2, to work with wineasio) with best sound quality with all sound routed through jack. When i start jack server with this command and settings:
killall jackd;killall pulseaudio;jackd -R -t 1000 -d alsa -P hw:0,0 -r 48000 -n2 -D
Firefox slows down, opens new pages slow and the scroll down is very very slow. I had this issue with other distros too. I suspect that it has to do with realtime ( which i need for my audio related apps like traktor through wine, ardour, ableton through wine etc) without being sure about it. Any idea why this is happening?

zabrielza wrote:I had this issue with other distros too.
This smells like hardware problem. Do this:
1. Kill pulseaudio, jack, and make sure they are killed
2. Make sure you do not renice anything or apply other such tweaks
3. Run jackd -d alsa
4. Use your system
5. If unsatisfactory, try jackd -d alsa -p 1024 -n 3
6. Use your system
Jack runs with realtime priority by default (no flag required), and we still use the audio group to provide that privilege. I also do not advocate the realtime kernel, but you may try it. Jack not functioning well (i.e. hampering other tasks significantly) on a standard kernel is cause for concern.
You can read/grep your dmesg and systemd journal for suspicious messages. You may try running real-time audio tasks in another operating system with your hardware, and upon success may proceed to debug the problem on Linux, possibly with the help of the alsa developers.
Or better yet, grab a supported semi-pro external audio device if jack is important for you. However, this may not help if the problem is somewhere deeper, e.g. at the hardware interrupt level.

Time Capsule 3T WiFi very slow, just 0.4Mbs.

When connected directly to the the internet cable the speed is over 2.5Mbs, but only 0.4Mbs through Time Machine 3T (802.11ac).
I tried to turn everithing off and turn them on one-by-one, from the internet radio receiver to the Time Machine, then MacAir 13 Mid 2013.
How can I fix it?
The AirPort Utility does not offer any resource to do it.
It had been running just fine since installed on October/2013 and I noticed that it was getting slower in the last 5 weeks and now it is slow all the time.
I can do the basic on MacAir but AppleTv just do not allow me to watch a movie on Netflix (I can browse through all windows but the movie won't start).
Thanks for an answer,

Just need to confirm a few things.. 2.5Mbps is very slow.. if you use b for bits as we try to do.. if you mean Bytes, then that is ok. We try and use B for Bytes.
from the internet radio receiver to the Time Machine, then MacAir 13 Mid 2013.
So you are getting internet via wireless.. not from standard cable or adsl modem?
What is the modem and is it a router as well??
How is the TC connected to the modem router and in what mode??
If you use any client on the TC wired, can you test it??
If you use wireless have you made sure to use all names that are short, no spaces and pure alphanumeric.
Mavericks now uses SMB networking by default so it can help..
More importantly the ipv6 is set correctly to Link-Local.

Why EP is very slow just after it is started?
