One specific MSAD account having very poor performance

We have one specific MSAD EPM account that takes forever to login, access a planning form and run a report. If this same user uses our testing native directory IDs he session is as fast as all other MSAD accounts.
If another MSAD account uses his workstation they encounter no problems (thus not a workstation problem)
We have dropped and added him back to the security groups, refreshed filters and reviewed his MSAD setup to make sure it is not different.
Looking for other avenues or tools to use to determine why this individual is having problems.
JTS

Had to share this will all,
Finally figured out what the problem was after sniffing through our entire network. It was a workspace preference for Accessibility Mode. For this user it was checked (File/Preferences/General/Accessibility Mode)
Once unchecked the system speed was normal to other users
Always the little things

MSI GE70 2OE-015NL very poor performance on battery power

Hey guys,
First of all I want to say that I'm really happy with my GE70 notebook. Everything works perfectly fine except for this one thing... When I play games on the notebook while on battery power, the performance is very poor. For example when I normally on AC power get around 250 FPS, it drops down all the way to around 40-60 FPS on battery power. In real demanding games this can be very annoying, since I have to play on AC power constantly for games like Battlefield 4. Although this isn't really a problem for me most of the time, I just don't think that's the concept of a notebook... I monitored some statistics using MSI Afterburner and I noticed that the GPU's core clock is clocked all the way down to a constant 135MHz whilst gaming and the memory is clocked all the way down to around 400MHz. I'm using a GTX 765M. I've already tried changing settings in the Windows power settings, the NVIDIA control panel and I even looked into the BIOS, but I couldn't find a solution to this problem. Apparently the GTX 700M series GPUs support Optimus technology which should give a decent battery life using the full power of your GPU, but for me it doesn't do so. The battery gets drained in around 45 minutes while gaming on very poor performance. I hope you guys can help me out!

Oyo,
All Gamer NB are not done for play in battery mode, battery life are short and the power provide by a battery are far from the power adapter, this mean the NB get less power and your CPU and VGA are working in lower mode = lower result.
This is normal because link to the battery, thepower adapter provide 120W, the battery 49W, you see the gap between them ^^
So for play games, use the power adapter and the battery together, this is the best way.

Why is the signal at my home so much weaker than when I moved here in February 2013? I only get one or two bars and very poor data service if any at all.

Why is the signal at my home so much weaker than it was when I moved here in February 2013? I get only one or two bars and very poor data service if any at all. Calling to ask the question results in a vortex of questions that have little to do with the problem and no resolution or answer.

I have a Droid Ultra phone. The signal reduction seems to only be in the general area of my home. If I go downtown, the signal improves to what it once was at home. Everything at my home is as it was when the signal was good, including cable TV service. There has been no new construction in the area that I know of.
Thanks for trying to resolve the issue. Just this morning while trying to view web pages, I found that I could not load any.

URGENT: Migrating from SQL to Oracle results in very poor performance!

*** IMPORTANT, NEED YOUR HELP ***
Dear, I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.
Anton

On the production system we have very poor DB performanceHave you identified the cause of the poor performance is not the queries and their plans being generated by the database?
Do you know if some of the queries appear to take more time than what it used to be on old system? Did you analyze such queries to see what might be the problem?
Are you running RBO or CBO?
if stats are generated, how are they generated and how often?
Did you see what autotrace and tkprof has to tell you about problem queries (if in fact such queries have been identified)?

Very poor performance on oracle linux 6.3 on virtual-box 4.2

I can confirm that there is no issue with Virtualbox 4.2 and Oracle Linux 6.3. I use it all the time. Performance should be near native and some aspects like disk I/O may even be faster. Your problem could be insufficient hardware, like missing x86_64 or hardware virtualization support. However, like rukbat wrote, this is not the right forum to discuss Virtualbox and your computer hardware here. I suggest to start with the Virtualbox documentation to verify your hardware is sufficient.

Very poor performance Windows RT with Citrix

Hi All,
I'm currently in a project with a customer implementing XenApp 7.6. The customer uses Dell XPS 10 tablets with Windows RT installed. We have installed the latest Receiver from the Microsoft Store and added a connection through a Citrix NetScaler Gateway
VPX version 10.5.
The user experience on the tablet is very very poor. This is extreme when browsing using Internet Explorer 11. On a normal Windows 8 client or a thin client with WES2009 the experience is good.
Besides the bad performance there's also a problem with the home/start button on the remote OS (Windows Server 2012 R2). The button isn't working or only after multiple tries.
This experience is also on a windows 8.1/10 machine with the Citrix Receiver from the store.
Any thoughts about the issue's above? What can we do to optimize the environment for working with the Citrix Receiver from the store?
Kind Regards,
René

Create a smart mailbox for one one specific email account?

It has been a long time since I've been in these forums, I have to update my computer model, ha!
Anyway, I notice that when I create a smart mailbox, the specific instructions pertain to both my .Mac account and my gmail account which are set up in the Mail application. I would like to make the smart mailbox rules only apply to the gmail account, but I can not find a way to do this. Is this possible?
I would also like to only include messages from my gmail inbox in my smart mailbox, instead of sent messages etc.

you can't combine AND and OR conditions is a smart mailbox. I really don't know why. it's a big oversight IMO. you can do it in finder smart folders. you can try something weird like making one smart mailbox which satisfies the conditions you wnat about matching words . then make another smart mailbox with the condition that a message is in the first smart mailbox AND in gmail inbox.

Can't send email from one specific .mac account

I have two .mac accounts on three different machines. My main email account gives me "cant send with server smtp message..." use a different server. I can send just fine with my other .mac acct on the same machine. But I can't send from my main .mac acct on any of the machines or the web client at home or work. I have created a new user from scratch and set up the .mac acct on it and still get the errors. So it doesn't seem to be a problem specific to machine, user, or network. Any suggestions would be greatly appreciated.
Thanks
iMac intel Mac OS X (10.4.6)

In your Account setup (via Mail Preferences) you may have to set up an Outgoing Mail Server (SMTP) entry. As an example I have a IMAP account and a POP account. The IMAP account has the server smtp.<imap_domain>.com and the POP account has mail.<pop_domain>.net.au. I also have other domain entries which come into play if I am visiting friends or colleagues and need to send or receive mail via their broadband links which have ISP's that differ to mine.

Macbook (mid 2012, 9,2) has very poor performance since the day I bought it (less than 2 months ago)

Problem description:
My macbook is extremely slow since the day I bought it (which was less than 2 months ago)…Came preinstalled with Mavericks and 4GB of RAM. Upgraded it to 16GB hoping that would help, but that did very little…then upgraded to Yosemite. That just made it worse. Formatted the whole thing and installed clean Yosemite. Still, every time I right click, I get the rainbow loading icon and it hangs. Every time I open any file, or click any app, it hangs for a few seconds, again with a loading icon. Every time I play a song on iTunes or even VLC for that matter, it stops multiple times, every few seconds. Feels like it’s “buffering” while I’m playing a song off my hard drive. It’s been bothering me for too long now…Any idea what the issue is exactly?

MOVED: K8MM3-V win2000 very poor performance

This topic has been moved to AMD64 ATI/SiS/VIA based board.
https://forum-en.msi.com/index.php?topic=105470.0

I've tried:
original install of win2000: problems as above
Fresh install of win2000 no service packs: same problems
Fresh isntall of win2000 with lastest drivers from MSI website: same problems
Fresh install of win2000 with service pack 4 (latest): same problems
Fresh install of winXP: No problems at all
As above but with latest MSI drivers: Still no problems at all
It's definitely related to win2000 and I suspect it must be a mobo driver issue?

Very slow performance with Motion

Using Motion 3.0.2 on a new gen MacPro 2 x 2.4 Quad Core Intel Xeon and 8GB Ram OSX 10.6.4
I'm having very poor performance in Motion the system was set to use 80% of the memory so I tried bumping that up to 90% and there was no change. Could this be the performance of the graphic card because I have recently seen a post regarding the 5770 card could this be related to these new cards?
The performance has been bad when using lots of particles in a project but also when just using two lines of text in the canvas so I don't believe that it is because I'm running Motion to extreme.

Text is a real performance killer in Motion because of Apple's insistence on redrawing the vectors in every frame. Unless I need remarkable interactions or 3D stuff, I usually export text layers as movies and bring them back in for that very reason.
No one really knows how the 5770 and 5870 cards compare directly agains our older 4870s. The online test geeks do not supply enough information to be helpful in evaluating their applicability to Motion.

Poor Performance with Fairpoint DSL

I started using Verizon DSL for my internet connection and had no problems. When Fairpoint Communications purchased Verizon (this is in Vermont), they took over the DSL (about May 2009). Since then, I have had very poor performance with all applications as soon as I start a browser. The performance problems occur regardless of the browser - I've tried Firefox (3.5.4), Safari (4.0.3) and Opera (10.0). I've been around and around with Fairpoint for 6 months with no resolution. I have not changed any software or hardware on my Mac during that time, except for updating the browsers and Apple updates to the OS, iTunes, etc. The performance problems continued right through these updates. I've run tests to check my internet speed and get times of 2.76Mbps (download) and 0.58Mbps (upload) which are within the specified limits for the DSL service. My Mac is a 2GHz PowerPC G5 runnning OSX 10.4.11. It has 512MB DDR SDRAM. I use a Westell Model 6100 modem for the DSL provided by Verizon.
Some of the specific problems I see are:
1. very long waits of more than a minute after a click on an item in the menu bar
2. very long waits of more than two minutes after a click on an item on a browser page
3. frequent pinwheels in response to a click on a menu item/browser page item
4. frequent pinwheels if I just move the mouse without a click
5. frequent messages for stopped/unresponsive scripts
6. videos (like YouTube) stop frequently for no reason; after several minutes, I'll get a little audio but no new video; eventually after several more minutes it will get going again (both video and audio)
7. response in non-browser applications is also very slow
8. sometimes will get no response at all to a mouse click
9. trying to run more than one browser at a time will bring the Mac to its knees
10. browser pages frequently take several minutes to load
These are just some of the problems I have.
These problems all go away and everything runs fine as soon as I stop the browser. If I start the browser, they immediately surface again. I've trying clearing the cache, etc with no improvements.
What I would like to do is find a way to determine if the problem is in my Mac or with the Fairpoint service. Since I had no problems with Verizon and have made no changes to my Mac, I really suspect the problem lies with Fairpoint. Can anyone help me out? Thanks.

1) Another thing that you could try it is deleting the preference files for networking. Mac OS will regenerate these files. You would then need to reconfigure your network settings.
The list of files comes from Mac OS X 10.4.

2) I think it is time to do a clean install of your system.
3) It's either the software or an intermittent hardware problem.
If money isn't an issue, I suggest an external harddrive for re-installing Mac OS.
You need an external Firewire drive to boot a PowerPC Mac computer.
I recommend you do a google search on any external harddrive you are looking at.
I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.
The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.
Has everything interface:
FireWire 800/400 + USB2, + eSATA 'Quad Interface'
save a little money interface:
FireWire 400 + USB 2.0
This web page lists both external harddrive types. You may need to scroll to the right to see both.

Here is an external hd enclosure.

Here is what one contributor recommended:
http://discussions.apple.com/message.jspa?messageID=10452917#10452917
Folks in these Mac forums recommend LaCie, OWC or G-Tech.
Here is a list of recommended drives:

Zfs/nfs poor performance compared to zfs/smb

I setup zfs with sharenfs on my solaris box and i'm having a very poor performance with nfs (about 1-3MB/s).
When i share the same zfs volume with sharesmb performance is very good (about 40-50MB/s) for a single disk zfs volume on a gigabit network.
Both tests where made using MAC OSX 10.5.2 client using a single iso file transfert (about 4Gigs).
I also mount through nfs my MAC client (using apple nfs share) from the solaris box and copy the file to the ZFS volume, nfs performance was very good in this case (45-50MB/s).
Why my solaris zfs/nfs sharing is so slow compared to mac nfs sharing or solaris zfs/smb sharing ?

I'm guess your talking about write performance ie your copying the ISO from a local drive to the ZFS/NFS drive.
The write performance of NFS/ZFS has been known to suck for a long time.
First make sure your running the latest solaris version (10U4) or a recent recommended patch set.
If not, upgrade and see if that helps.
Unfortunately, the solaris developers have a (some say overly) strict interpretation of the coherence requirements of the NFS spec and what it implies about caching data in memory and flushing to disk.
This is discussed a little here
and
here
Their position (as I understand it) that their implemation provides the best performance that can be obtained while maintaining adherence with the relevant standards and the fact that every other NFS implementation has streets better performance just means that everyone else is non conforming.
Anyway maybe can try the solution that the "best practices" suggests ie using a local drive as an intent log.
If that doesnt work, try setting zil_disable (�set zfs:zil_disable=1′ to /etc/system).
You will have to weigh the significance of the purported reliability issues of that solution for yourself.
Basically what it comes down to is that if your nfs server crashes and the client doesnt, but keeps cheerfully writing away. Then some of what it wrote maybe lost. Even silently a part in the middle.
One other thing to check, the storage isn't coming off a SAN is it?
If it is you can try "set zfs:zfs_nocacheflush=1" instead of zil_disable. Its a less aggressive variant that can reduce issues with san storage.

CRIO Poor Performance - Where have my MIPS gone?

I have a cRIO based system that is used to control a motor for a particular application. The application has been developed and enhanced over the years and is currently using about 50% of the CPU. The RT Controller is a cRIO-9012. I have recently been asked to add a 1 kHz (or more) loop function to the cRIO application. I can only achieve a maximum loop rate of about 200 Hz. When I told the customer this, he asked how fast my controller was, to which I replied 400 MHz. “Where is all the CPU power going?”, he asked. He's now thinking of replacing the cRIO Controller with an mbed with C code to get the performance he requires, which is a pity since I'd like to continue developing the application in LabVIEW.
Following on from his question, “where is all the CPU power going?”, I decided to write a simple application to test the cRIO 9012's performance. Below is the code I used to perform the evaluation:
With just the bottom loop running, which reports CPU load over the cRIO Controller's serial port, I have a CPU load of 7.0%. This is the baseline.
I then add the "execution" loops as shown above the bottom loop, one at a time and recoded the CPU load. Here are the results:
1 Loops - 18.3% load (11.3% extra)
2 Loops - 29.4% load
3 Loops - 45.5% load
4 Loops - will not run!
I have two problems/concerns.
Concern 1
The cRIO 9012 has a 400 MHz processor, which has 760 MIPS of processing power. The rate of the simple loop is 2 kHz and each loop takes about 11% of the CPU power. That is, each loop uses up 83.6 MIPS and each loop iteration uses up 41,800 instruction cycles. Where are the 41,800 instructions going? Even if there was a context switch after each loop iteration, this would account for 150 to 200 instruction cycles. Each loop is only doing an integer increment, timing check, compare and branch. These should only take up about 4 instruction cycles (8 if you want to be generous). If this was programmed in C, you could get bare metal performance that allows a single loop rate of something like 40 MHz or with an RTOS something like 2 MHz. Instead, my maximum loop rate is something like 20 kHz.
Where are the "wasted" 41,600 instructions per loop iteration going? This is only 0.5% efficient!
Concern 2
Why does adding the 4th "execution" loop cause the application to halt (or at least not send data over the serial port)?
I like programming on the desktop using LabVIEW and I like programming the FPGA using LabVIEW. The RT Controller is however becoming an embarrassment. Is it really the case that the best additional loop rate I can add to an existing application that already uses 50% of the cRIO Controller's CPU can only be 200 Hz maximum?

Thanks for all the feedback.
MajorTom,
Changing to timed loops instead of while loops makes the performance worse. For 2 Loops, rather than a CPU load figure of 29.4% (22.4% after removing base load) it shoots up to 78.4% (71.4% after removing base load). That is, it runs about 3 times slower, which takes the "efficiency" down from 0.5% to 0.15% efficient.
TimothyA,
I tried making the "execution" loops subVIs (with Preferred Execution System = other 1, with the top level = other 2) and that solved the four "execution" loops problem. Thanks, one of my concerns is now resolved (I'll mark it as such once the conversation quietens down).
The execution time is still large with the 2 loops taking 29.1% of the CPU, which is the same as before.
I tried using the "reduced" us wait next multiple CLN.vi, but it appears to be in LabVIEW 2014 and I'm using LabVIEW 2013. Any chance of resaving it as LabVIEW 2013?
crossrulz,
Thank you for pointing me to the table in the CompactRIO Developer's Guide. I assume you’re talking about Figure 3.5. Priorities and Execution Systems available in LabVIEW Real-Time. I didn't realise that Execution Systems are limited in the number threads (would be nice to get a warning when this happens). This will make interesting reading and experimentation.
All,
I’ve tried various loop limiting rates including Timed Loops and While Loops with RT Wait Until Next Multiple, RT Wait, Wait Until Next Multiple and Wait and the best perform is from the two RT waits. The worst performance was from the Timed Loops.
In summary, I’ve solved the problem regarding how to run more parallel loops, but I still get very poor performance with each loop interaction taking about 41,800 instructions when it “should” take more about 200 instruction cycles. All I want is to be able to run a loop at at least 1 kHz on my cRIO-9012 when I already have an application that takes up about 50% of the CPU. I have the threat of the code being moved to an mbed using C, which I’m trying to resist. Surely a 400 MHz controller can have a 1 kHz loop and not take up more than 10% of the CPU.

Poor performance with WebI and BW hierarchy drill-down...

Hi
We are currently implementing a large HR solution with BW as backend
and WebI and Xcelcius as frontend. As part of this we are experiencing
very poor performance when doing drill-down in WebI on a BW hierarchy.
In general we are experiencing ok performance during selection of data
and traditional WebI filtering - however when using the BW hierarchy
for navigation within WebI, response times are significantly increasing.
The general solution setup are as follows:
1) Business Content version of the personnel administration
infoprovider - 0PA_C01. The Infoprovider contains 30.000 records
2) Multiprovider to act as semantic Data Mart layer in BW.
3) Bex Query to act as Data Mart Query and metadata exchange for BOE.
All key figure restrictions and calculations are done in this Data Mart
Query.
4) Traditionel BO OLAP universe 1:1 mapped to Bex Data Mart query. No
calculations etc. are done in the universe.
5) WebI report with limited objects included in the WebI query.
As we are aware that performance is an very subjective issues we have
created several case scenarios with different dataset sizes, various
filter criteria's and modeling techniques in BW.
Furthermore we have tried to apply various traditional BW performance
tuning techniques including aggregates, physical partitioning and pre-
calculation - all without any luck (pre-calculation doesn't seem to
work at all as WebI apparently isn't using the BW OLAP cache).
In general the best result we can get is with a completely stripped WebI report without any variables etc.
and a total dataset of 1000 records transferred to WebI. Even in this scenario we can't get
each navigational step (when using drill-down on Organizational Unit
hierarchy - 0ORGUNIT) to perform faster than minimum 15-20 seconds per.
navigational step.
That is each navigational step takes 15-20 seconds
with only 1000 records in the WebI cache when using drill-down on org.
unit hierachy !!.
Running the same Bex query from Bex Analyzer with a full dataset of
30.000 records on lowest level of detail returns a threshold of 1-2
seconds pr. navigational step thus eliminating that this should be a BW
modeling issue.
As our productive scenario obviously involves a far larger dataset as
well as separate data from CATS and PT infoproviders we are very
worried if we will ever be able to utilize hierarchy drill-down from
WebI ?.
The question is as such if there are any known performance issues
related to the use of BW hierarchy drill-down from WebI and if so are
there any ways to get around them ?.
As an alternative we are currently considering changing our reporting
strategy by creating several higher aggregated reports to avoid
hierarchy navigation at all. However we still need to support specific
division and their need to navigate the WebI dataset without
limitations which makes this issue critical.
Hope that you are able to help.
Thanks in advance

Hi Henry, thank you for your suggestions although i´m not agree with you that 20 seconds is pretty good for that navigation step. The same query executed with BEx Analyzer takes only 1-2 seconds to do the drill down.
Actions
suppress unassigned nodes in RSH1: Magic!! This was the main problem!!
tick use structure elements in RSRT: Done it.
enable query stripping in WebI: Done it.
upgrade your BW to SP09: Has the SP09 some inprovements in relation to this point ?
use more runtime query filters. : Not possible. Very simple query.
Others:
RSRT combination H-1-3-3-1 (Expand nodes/Permanent Cache BLOB)
Uncheck prelimirary Hierarchy presentation in Query. only selected.
Check "Use query drill" in webi properties.
Sorry for this mixed message but when i was answering i tryied what you suggest in relation with supress unassigned nodes and it works perfectly. This is what is cusing the bottleneck!! incredible...
Thanks a lot
