Possible solution to wireless/bluetooth/and system performance issues.

I had a TON of issues with Leopard after my Tiger Install, network, bluetooth, video playback, iTunes playback, system performance and freezing just to name a few. I tried everything (reseting PRAM, etc.) to fix the problem and have done a variety if installations half a dozen times. Yesterday I took out my 3rd party memory I had installed (Corsair if anyone cares) and did an erase and install. I've had no problems so far and everything seems to be running great. I'll keep everyone posted on any progress. You may want to try this if you think you may have the same issue.

Hi
I may have the solution to slow performance when using multi core processing. I was testing out realflow 2013 and noticed simulations were talking a long time to finish when using maximum threads 32. I set the threads to 8 and the simumlation was twice as fast which did not make any sense to me. The simulation was taking 1min 24 secs to finish using 32 threads and 45sec using 8 threads. I realized their has to be a problem here. So I went into my BIOS and disabled Hyper Threading. So now instead of having 32 threads I only have 16 threads. When i went back to try the same simulation again this time the 16 threads was only taking 24secs to finish. and the 8 threads was taking 35secs to finish. This made a lot more sence to me.
Anyway so once I realized that turning off Hyper Threading fixed my simulation problem maybe it might be the cause of my slow performance in AE using multi processing. I tried AE and now multi processing is working great very fast now and stable. MP renders start right away now instead of getting stuck on frame 2 or saying initializing background processes and never ever doing anything. Before I had to keep disabling MP and re-enabling it in AE to get it to start working again and still it wasen't very stable
If anybody is having issues with slow performance from their Multi processor systems try disabling Hyper Threading in the BIOS it might just fix your problem.
Hope this helps

D200 Creative Wireless/Bluetooth Speaker system question?

Is the iPhone 4S and iPhone 5 compatible with the D200 Creative Wireless/Bluetooth Speaker system? I understand it says, "all other bluetooth enabled devices". Just want to make sure...thanks.

hi Adtrix,
Can you try making sure that the bluetooth driver from Lenovo support site is installed,
If your system is running Windows 8, Check the Lenovo Energy Management 7 version is installed. If not
uninstall the Lenovo Energy Management from Control Panel / Programs and try donwloading this.
Lenovo Energy Management Software 7.0
cagt26ww.exe
21.2MB
After installation
try hitting Fn+F5 and check the if bluetooth radio status is "ON'

Classification data organization and system performance

We are planning on setting up classification for the material master. Reviewing discussions on the topic indicate the potential for system performance issues with search response and file sizes. Performance is dependent on several factors such as the number of material numbers, classes and characteristics, use of interval values, depth of hierarchies ect.
We have a significant number of material numbers, looking to have at least 15 classes with about 200 total characteristics. The extent of superior class linkage is undetermined at this time.
I am looking for a guideline or tool that would help us understand if our design is efficient or will lead to long term performance issues. Is there a resource or documentation that gives some examples of situatinos where classification got our of hand and why?
Thank you
Brian

Hello Brian,
There is no document or guidlines as such however you should keep the tables upto date . Also we recommend to use CLST for updating statistics regularly. Are you looking to assign 15 classes for material ? It should not affect the performance as much but you should keep characteristics to minimal in that case. Also are you using VC as there are lot of recommendations for VC but in general for classification keeping the stats upto date is most important.
Thanks

When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

What makes you so sure it isn't software?
The camera can be focused by take the point of focus on the touch screen.
If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

How to update this query and avoid performance issue?

Hi, guys:
I wonder how to update the following query to make it weekend day aware. My boss want the query to consider business days only. Below is just a portion of the query:
select count(distinct cmv.invoicekey ) total ,'3' as type, 'VALID CALL DATE' as Category
FROM cbwp_mv2 cmv
where cmv.colresponse=1
And Trunc(cmv.Invdate) Between (Trunc(Sysdate)-1)-39 And (Trunc(Sysdate)-1)-37
And Trunc(cmv.Whendate) Between cmv.Invdate+37 And cmv.Invdate+39the CBWP_MV2 is a materialized view to tune query. This query is written for a data warehouse application, the CBWP_MV2 will be updated every day evening. My boss wants the condition in the query to consider only business days, for example, if (Trunc(Sysdate)-1)-39 falls in weekend, I need to move the range begins from next coming business day, if (Trunc(Sysdate)-1)-37 falls in weekend, I need to move the range ends from next coming business day. but I should always keep the range within 3 business days. If there is overlap on weekend, always push to later business days.
Question: how to implement it and avoid performance issue? I am afraid that if I use a function, it greatly reduce the performance. This view already contains more than 100K rows.
thank you in advance!

You are already using a function, since you're using TRUNC on invdate and whendate.
If you have indexes on those columns, then they will not be used because of the TRUNC.
Consider omitting the TRUNC or testing with Function Based Indexes.
Regarding business days:
If you search this forum, you'll find lots of examples.
Here's another 'golden oldie': http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:185012348071
Regarding performance:

Article Listing and system performance

While creating physical inventory document, we experienced running each site for 25 to 30 minutes. With over 140 sites, it will take approximately 3 days just to create the PID's. We had consultants looking into our system and suggested that we could delist to improve the PI process and overall system performance. Through initial testing of delisting (WSP6), it did not help the PI processing time(creating PID's through MI31). So, I thought that we should archive site data only, but not at Client level, meaning delete all site extensions. Can somebody tell me (a) if this is the right approach?, (b) what are the things to watch out for? (c) can I list the article again if later we find a need for it?
Looking forward to some help. Thanks.

Re-posting this message. Can somebody help?
Thank you.

HD and System Performance Question

Hello,
I've a standard 160 Go 8 Mo cache HD (from origin) in bay 1 with the OS X System, and 2 other 300 Go 16 Mo Maxtor HD in bay 2 and bay 3.
First, I'd kike to know if it makes a real difference if using a 16 Mo cache HD instead of a 8 Mo for the OS X performance.
Then, if I decide to migrate the OS X in the HD in bay 2 or 3, is there any influence on performances or does OS X have to be installed in HD in bay 1 only ?
Thanks for your help and support.
Lionel.

I use to think that a 16MB cache made a lot of difference. However, based on testing I found that the difference is usually minor. As an example see how little difference the Seagate 16MB provides in this AMUG review:
http://www.amug.org/amug-web/html/amug/reviews/articles/seagate16/
The real performance factor is how fast the hard drive is not how big the cache is. A medium speed drive will not become fast by slapping a 16MB cache on it. The Maxtor Maxline III's all have 16MB and they perform very well. However, placing a 16MB cache on a Seagate 7200.8 or 7200.9 does not increase the speed of the hard drive significantly.
Talk to any sales person and they will always tell you that you will notice a difference in performance between the same drive with a 8MB vs 16MB cache. I found this generic response not to be true.
While a fast hard drive usually has a 16MB cache. The 16MB cache in and of its self did not make the hard drive fast.

Bluetooth and System Preferences Fault

I've had some problems with bluetooth already, it wouldn't connect to my phone or laptop to send files. I hadn't got round to doing anything about it though.
Just now my wirelss keyboard and mouse have stopped responding and System Preferences too. System preferences froze, I tried to "force quit" which seems to have failed but I can't open the system preferences window now. I get this error message:
An unexpected error occurted (error code -600)
I tried Disk Repair and got this message:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
Not solved the problem though. Anyone any ideas?

FYI, those SUID warnings are not to worry (according to Apple) and get fixed in 10.5.2.

My solution for: Slow Installs and poor performance

So up until today, most of anyting on XP or even vista 64 ultimate was taking a very long time to install or copy from one part of the drive to another. Startup would grow longer and game performance was dying and only once ever did reinstalling the OS do anything. No matter what I did, nothing would fix the problem.
I ran multiple utilities (disk utility, disk warrior, tech tool deluxe, etc) but none said that there was a hardware problem. But this issue I was having (and I know some of you do) was definitely related to the computer. From my experience, I determined that there was no way this mac was perfect.
So I scheduled a service and repair at my apple store (under warranty). When it was done a few days later, sure enough, I was told that even though the utilities we users can use on our end to diagnose problems didn't find any problems, the hard drive did not pass apple's detailed inspection and was replaced.
In conclusion, I say that if you are having this problem, run disk utility and if you have the extra protection plan, download the Tech Tool Deluxe that apple provides on the support site. Disk utility may find some permission and disk issues but if Tech Tool doesnt find anything even on the surface scan, take it in to the apple store to have a Genius look at it. If it's not under warranty, it's up to you whether or not you want to spend that money. Overall, my computer both on Leopard and XP now runs just as it should.
Hope that helps.

SRM 5 BBPSTART - System ID and System Messages issues

Hi all,
We just upgraded to SRM 5.0 from SRM 3.0
The shopping cart logon page(bbpstart) doesn't show System ID and also the system Messages also doesn't work on browser when we set message by sm02.
I already checked "System ID" and "System messages" from "Select Display" under System Logon Settings from bbpstart>Error Pages>Logon Errors>Configuration>System Logon Settings.
I searched over the net and can't find anything. I only found a notes for the System messages, but it was for the older release and SRM 5 already applied that note. So I don't know what else I can do.
Thanks for the itime.

Hello Thomas,
It is not possible to run a system landscape with 2 identical SID's. And even if you do get it running in some kind of freeky way the system would be very instable (how would you know a transport has gone to the right system?).
A system copy and a <SID> change is still possible. However, SAP recommends to do an export and an import of your database. Allthough this is the best and the least confusing way (and labour extensive), it is not really necessary.
If you do a backup/restore procedure with a <SID> change, lets say from PRD to DEV, you will end up with a system that has DEV as <SID> but your tablespaces will look like PSAP-PRD-620. The owner of the database will also be sapprd. This is no problem at all to run the system, it is only confusing.
I know it works, I've got it running. I've also got a sandbox running with user saptsc and database owner cbdamd and <SID> CBD.
Kind regards,
Pascal Ottens

CAT4900M and NetApp - Performance issue

Hi,
I'm struggling with a performance issue between our two NetApp Fas3170-devices.
The setup is quite simple: Each NetApp is connected via two TenGig interfaces to a CAT4900M. The 4900M's are also connected via two TenGig interfaces. Each pair of connections are bundled into an Layer2-etherchannel, configured as a dot.1q trunk. Mode is set to 'ON' on both the 4900 and the NetApp. According to NetApp documentation, this configuration is supported. Across each etherchannel, the vlans 219 and 220 are allowed. Two partitions are configured on the NetApp's, one being active in our primary datacenter and another in our secondary datacenter. Vlan219 and Vlan220 are configured for each the two partitions, using HSRP for gateway redundancy.
None of the interfaces nor the etherchannels shows any signs of misconfiguration. All links are up and etherchannels working as expected, well almost. Nothing indicates packet loss, crc-errors, Input/Output queue-drops or anything the would impact performance. Jumboframe is not configured, although this has been discussed.
The problem is, that we're unable to achieve satisfactory performance, when for instance, performing a volume copy between the two NetApp partitions. Even though we have a teoretical bandwidth of 20Gbps end-to-end, we never climb above 75-80 Mbytes of actual transfer-rate between the two NetApps. So performancewise, is almost looks as if we're "scaled" down to a 1Gig link. No QoS or other kind of ratelimiting has been implemented on the 4900's, so from a network point of view, the NetApps can go full-throttle. NetApp sw has been updated and configurations for both NetApp and 4900's have been revised by NetApp engineers and given a "clean bill of health".
The configuration for the 4900->NetApp etherchannel/interfaces is as follows:
interface TenGigabitEthernet1/5
description *** Trunk NetAPP DC1 ***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 219,220
switchport mode trunk
udld port aggressive
channel-group 2 mode on
spanning-tree bpdufilter enable
interface TenGigabitEthernet1/6
description *** Trunk NetAPP DC1 ***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 219,220

switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 219,220
switchport mode trunk
spanning-tree bpdufilter enable
spanning-tree link-type point-to-point
Configuration for 4900->4900 interfaces/etherchannel is as follows:
interface TenGigabitEthernet1/1
description *** Site-to-Site trunk ***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 10,219,220
switchport mode trunk
udld port aggressive
channel-group 1 mode on
interface TenGigabitEthernet1/2
description *** Site-to-Site trunk ***

description *** Site-to-Site trunk ***
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 10,219,220
switchport mode trunk

Does anyone have similar experiences or suggestions as to why we're having theese performanceissues?
Thanks

Hi,
Thanks for your reply.
I take it, that you mean baseline performance between the two NetApp's. Well, that's really out of my hands, as another department is responsible for the NetApp's. I'm not aware of any baseline performance, nor have I seen any benchmark tests or anything, that could give me hint.
Just as you suggest, I've gone through the switch-setup systematically. Basically, starting with the physical layer and working my way up. So far, I've found nothing that would indicate a physical problem. The switchport/etherchannel setup has been verified by my peers and also verified by NetApp according to the configuration on the NetApps, as well as the various best-practice documentation availible. Futhermore, I haven't seen any signs of packets drops, crc-errors, massive re-transmissions or anything like not, neither on the switches nor the NetApps.
Recently we had a status-meeting with our NetApp-partner and it looks to me like they're persuing the logical setup on the NetApps, as the're apparently a number of settings etc. that needs adjustment. Also, we're waiting for NetApp tech-support to comment on the traces, config-dump etc. we've send to them.

Hard drive noise and system performance.

Just like normal, my hard-drive makes noises (normal clicking, etc). When I'm doing something though, like typing, the system slows down for just a split second once a noise it made, stops registering my letters and then types all the letters that weren't regestered. (Keep in mind, this is over a one second period).
For another example, when I launch dashboard, the widgets will start to appear on screen, stop for a (not even a) second, then the widgets will fall into place like they should. I have run disk utility multiple times, and each time it says that the HD is fine.
Is this behavior normal? I can live with it, it's just kind of annoying.

lol, I was going to add "as long as it's not doing that all the time" ...but was hoping for the quick fix. You might want to check your Activity Monitor and see which program or background process is causing the activity ...have you installed anything lately that coincided with this problem? You also might want to try booting into Safe Mode to see if things still persist.

Publish HTML to xMII 12.0 and system performance is poor

Hi all,
I'm having an issue since we upgraded to 12.0.   When I publish my page to MII, the whole system slows down. This lasts forever. ( 2 - 3 minutes) And then the HTML pages return to normal processing speed.
As I develop, I publish many times in one day or even an hour.   Has anyone else experienced this? Is there a way to "fix" it? Any settings/changes?
Thank you,
Michelle

Well - maybe publishing a lot not the right thing to do.
It's my development system.   The way I program is by pieces.   I do the first change. Publish.   Test to see if there are any errors. If there are errors, I correct and then publish again.
Next - I add the next part of requirements and then publish again.
I will publish a lot if I'm having trouble with a piece of code.
I don't know of anyway to test my HTML page prior to publishing.
Michelle

Trash and System Performance

Need to know for company SOP reasons whether or not keeping thousands of files in the trash for weeks affects mac performance in any way. I always remember from OS 7 and up that you wanted to keep the trash relatively clean for best finder performance. I remember also having issues running maintenance on mac's with a large number of trash files that were not yet deleted. Are there any links that you can provide on the this subject. Thanks in advance.
~b

*"Need to know for company SOP reasons whether or not keeping thousands of files in the trash for weeks affects mac performance in any way."*
Unless the hard drive is almost full, the amount of files stored on it, whether they are in the trash or not, does not affect performance.
