X6450 network performance issue
We are seeing a network performance issue using the Blade 6000 chassis with two (10x 1 Gbps Ethernet) NEM modules. The x6450 blades in the chassis have Solaris 10 u7 installed. In our tests, we used two blades in the following manner: each blade had only one network interface connected (and plumbed in the OS level) and each blade was connected to a different NEM. Both blades were connected to the same gigabit switch. There were two other test systems (x2270-s) also connected to the same switch. We ran the following tests:
both the application client and server are on the same blade (i.e. application is using the loopback network interface): n operations/second (the number here is irrelevant, only the relation to other test numbers are relevant)
application client on first blade, server on second blade: 0.77 x n operations / second (i.e. 23% degradation)
application client on blade, server on x2270: 0.77 x n operations /second (i.e. 23% degradation)
application client on x2270, server on blade: 0.75 x n operations /second (i.e. 25% degradation)
We ran similar tests with the x2270. We did not see any difference between running the test on the loopback interface vs. running the test between two x2270-s.
Is there a known issue with these network modules or their drivers?

Just use a high interval and you see how much throughput you have in that time
example: dlstat vnet1 120

Solaris 9, V210, bge0 network performance issue
Setup: Solaris 9, V210, single network (bge0).
ndd shows: 100FD
LAN Switch set to 100FD
Network performance bad, in fact very bad. System shows upwards of 19% collisions with netstat -- odd since FD should have no collisions. Network folks have checked switch settings and they are 100FD. I have checked more than once that ndd returns 100FD.
I am not sure what to check next. Thanks for any help you can provide in what to check next or pointing me to something I have missed.
Thanks - WesMeans your system and the switch aren't playing nicely.
Anytime a Sun internal is showing collisions (don't care what ndd says), it means the interface is probably flip flopping between FD and HD (causing your collisions). The flip flops are causing performance to be MUCH worse then just the collisions ever would.
You might try a new factory made CAT5 network cable.
Then if that doesn't work, you should try using ndd to force the bge interface to 100FD and forcing the switch to 100FD. -
I've just had a new ISP hookup. My WiFi is blazing fast. But my Mac network speed is slowwwww.
Speedtest.net just reported:
Ping: 253ms
Download: 1.12Mbps
Upload: 0.43 Mbps
On my iPad via Wifi, I get:
Ping: 19ms
Download: 13.88Mbps
Upload: 0.90Mbps
My Mac I think dates back to about 2005/6, even though you would think 2008 based on sites like everymac.com. But I bought it long before 2008.
The only modification I've made to it has been to bump it from 2GB to 4GB memory. That slowed down the bootup, but not ridiculously.
How can I diagnose fix this network issue?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, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
Oracle CPU Jan 2009 cause performance issue
I did installed Oracle CPU Jan 2009 on HP-UX machine. But once the installation is completed, users complaint saying that it takes more than 1 minutes to open a new ticket on that application. With this, it cause a backlog processess increase tremendously.
Will the CPU Jan 2009 patch cause any of the network performance issue:
Server: HP-UX Itanium 64 bit
Database: Oracle 10.2.0.3.0
Instances: 2 instances running on this server.
Edited by: user3858134 on Oct 26, 2009 9:30 PMI believe the latest CPU Patch for Oracle 10.2.0.3 on HP is CPU Jan 2009 only.Don't you think your database should be on 10.2.0.4?
Anyways, do you have any benchmark statspack/AWR report? Can you compare that with the latest one? Do you see any difference?

AT&T USBConnect Lightning performance issues with Snow Leopard
I recently purchased the AT&T USBConnect Lightning wireless data adapter and attempted to install it on my 15" MBP but ran into global network performance issues afterward so I wanted to check with anyone here who may have the same adapter. I noticed that the adapter has software drivers preloaded on the device that need to be installed on my Mac. Looking at the notes, it refers only to Mac OSX 10.4.11 or better and no mention of Snow Leopard so I'm now very concerned. The notes state that once the drivers are installed, that I'm required to reboot my computer which leads me to think the drivers may have affected MTU and other settings that might also impact performance with my other network adapters.
Appreciate any feedback you might have with this scenario.
Thanks so much!I give up

Performance Issue: Central Instance not utilizing full network resources.
Hi All,
I have experienced a problem regarding network usage by central instance.
At random times, even at peak load, SAP application server utilizing not more than 0.30%-0.35% of network resources, resulting in very poor performance.
As Primary observation, i have checked at operating system level that no other service/application is consuming network at that time.
Please help, how i can monitor/check and enhance the network resources utilization to the fullest for better performance.
Thanks in advance.
Regards
SurjitSAP application server utilizing not more than 0.30%-0.35% of network resources, resulting in very poor performance.
To be honest with you I can't see the network to been the performance issue unless you have serius trouble with network latency or maybe your system been located in a remote location.
You can check the average GUI time (in milliseconds) in ST03N, then you can make conclutions on if the info travelling to the frontend is been compromised because of network issue.
Also, usually comunication in between the instances should be based on a private fast VLAN to allow free traffic in between them

Performance issues with LOV bindings in 3-tier BC4J architecture
We are running BC4J and JClient (Jdeveloper 9.0.3.4/9iAS 9.0.2) in a 3-tier architecture, and have problems with the performance.
One of our problems are comboboxes with LOV bindings. The view objects that provides data for the LOV bindings contains simple queries from tables with only 4-10 rows, and there are no view links or entity objects to these views.
To create the LOV binding and to set the model for the combobox takes about 1 second for each combobox.
We have tried most of tips in http://otn.oracle.com/products/jdev/tips/muench/jclientperf/index.html, but they do not seem to help on our problem.
The performance is OK (if not great) when the same code is running as 2-tier.
Does anyone have any good suggestions?I can recommend that you look at the following two bugs in Metalink: Bug 2640945 and Bug 3621502
They are related to the disabling of the TCP socket-level acknowledgement which slows down remote communications for EJB components using ORMI (the protocol used by Oracle OC4J) to communicate between remote EJB client and server.
A BC4J Application Module deployed as an EJB suffers this same network latency penalty due to the TCP acknowledgement.
A customer sent me information (that you'll see there as a part of Bug# 3621502) like this on a related issue:
We found our application runs very slow in 3-Tier mode (JClient, BC4J deployed
as EJB Session Bean on 9iAS server 9.0.2 enterprise edition). We spent a lot
of time to tune up our codes but that helped very little. Eventually, we found
the problem seemed to happen on TCP level. There is a 200ms delay in TCP
level. After we read some documents about Nagle Algorithm, we disabled a
registry key (TcpDelAckTicks) in windows2000 on both client and server. This
makes our program a lot faster.
Anyway, we think we should provide our clients a better solution other than
changing windows registry for them, for example, there may be a way to disable
that Nagle's algorithm through java.net.Socket.setTcpNoDelay(true), in BC4J,
or anywhere in our codes. We have not figured out yet.
Bug 2640945 was fixed in Oracle Application Server 10g (v9.0.4) and it now disables this TCP Acknowledgement on the server side in that release. In the BugDB, I see backport patches available for earlier 9.0.3 and 9.0.2 releases of IAS as well.
Bug 3621502 is requesting that that same disabling also be performed on the client side by the ORMI code. I have received a test patch from development to try out, but haven't had the chance yet.
The customer's workaround in the interim was to disable this TCP Acknowledgement at the OS level by modifying a Windows registry setting as noted above.
See Also http://support.microsoft.com/default.aspx?kbid=328890
"New registry entry for controlling the TCP Acknowledgment (ACK) behavior in Windows XP and in Windows Server 2003" which documents that the registry entry to change disable this acknowledgement has a different name in Windows XP and Windows 2003.
Hope this info helps. It would be useful to hear back from you on whether this helps your performance issue. -
Performance Issues with Acrobat Reader 11.0.0.2 when secure mode is enabled
Hello All,
We are experiencing sporadic issues with Acrobat 11.0.0.2 across our domain, users are reporting performance issues when opening PDF documents whether locally or from a network share.
We have found that turning off Secure Mode helps towards reducing this delay and in the cases it doesn't we are repairing the installation and/or reinstalling the application.
Due to the security implications we need to leave this turned on, I am wondering if anyone has encountered this issue and what steps were taken towards resolving it?
I also wonder whether the white list function in the new release 11.0.0.3 would be a solution to this issue?
Kind Regards,
Ryan McCartyNo probelm, so....
We had no problems with Adobe Reader 9 and 10, we encountered the issues when upgrading to 11.0.0.2.
Initially we found that turning off the Protected Mode, helped but did not resolve the issue.
We tried;
1. Turn off protected mode - issue still present
2. Clearing the recent file registry using the below registry path and deleting the keys underneath it.
HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\11.0\AVGeneral\cRecentFiles (this does not turn recent files off permanently). - works but needs clearing regularly
3. Turning off welcome screen by creating - HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown\cWelcomeScreen - works to improve app open speed.
4. uninstall/reinstall of 11.0.0.2 - works most likley due to the recent files being cleared.
5. upgrade to 11.0.0.3 - issue still present
Following reboots the issue is still present.
When Adobe Reader is the only application open this issue is still present.
As mentioned I have no systems available which I could test this issue using 11.0.0.1 as we have fixed them, albeit temporarily using the reinstall method.
I am concious that this issue is going to reoccur once that cache (recent files) builds back up because the fix above (#2) is clearing the recent files cache NOT disabling it. -
Performance issues with Homesharing?
I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
Has anyone some suggestions?Hi,
you should analyze the db after you have loaded the tables.
Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
If yes:
make sure your sequence caches (alter sequence s cache 10000)
Drop all unneeded indexes while loading and disable trigger if possible.
How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
Is it possible using a direct load? Or do you already direct load?

Performance issue in DB need help with analysing this ADDM report
Hi,
My environment:
Os: RHEL5U3 / 11.1.0.7 64 bit / R12.1.1 64 bit
Issue:
Few days are am facing serious of performance problem in our Production instance. Normally the issue will occur 5 to 10 minutes occasionally per day. At the time of issue we not able to access the EBS application its taking time to load. But backend all the oracle, listener and apps services are up and running. No locks at table and session level. Cpu and memory usage is normal.
We have monitored using "Enterprise Manager" for this issue and we found the wait session present more in Active session tab. At this time EBS application is not able access its loading too time. After some time the in Active session tab the wait session came normal and when we try to access the EBS application its working fine.
We try to find the cause of the issue by running addm report. But am not able to understand what its says. Kindly suggests me

Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

Performance Issue in Oracle EBS
Hi Group,
I am working in a performance issue at customer site, let me explain the behaviour.
There is one node for the database and other for the application.
Application server is running all the services.
EBS version is 12.1.3 and database version is: 11.1.0.7 with AIX both servers..
Customer has added memory to both servers (database and application) initially they had 32 Gbytes, now they have 128 Gbytes.
Today, I have increased memory parameters for the database and also I have increased JVM's proceesses from 1 to 2 for Forms and OAcore, both JVM's are 1024M.
The behaviour is when users are navigating inside of the form, and they push the down button quickly the form gets thinking (reloading and waiting 1 or 2 minutes to response), it is no particular for a specific form, it is just happening in several forms.
Gathering statistics job is scheduled every weekend, I am not sure what can be the problem, I have collected a trace of the form and uploaded it to Oracle Support with no success or advice.
I have just send a ping command and the reponse time between servers is below to 5 ms.
I have several activities in mind like:
- OATM conversion.
- ASM implementation.
- Upgrade to 11.2.0.4.
Has anybody had this behaviour?, any advice about this problem will be really appreciated.
Thanks in advance.
Kind regards,
Francisco Mtz.Hi Bashar, thank you very much for your quick response.
If both servers are on the same network then the ping should not exceed 2 ms.
If I remember, I did a ping last Wednesday, and there were some peaks over 5 ms.
Have you checked the network performance between the clients and the application server?
Also, I did a ping from the PC to the application and database, and it was responding in less than 1 ms.
What is the status of the CPU usage on both servers?
There aren't overhead in the CPU side, I tested it (scrolling getting frozen) with no users in the application.
Did this happen after you performed the hardware upgrade?
Yes, it happened after changing some memory parameters in the JVM and the database.
Oracle has suggested to apply the latest Forms patches according to this Note: Doc ID 437878.1
Thanks in advance.
Kind regards,
Francisco Mtz. -
EA4500 – Smart Wi-Fi interface and Windows Network Map issues
I purchased this Router about 2 weeks ago as a phased upgrade of our Home Network, primarily to enhance media streaming. It has the latest firmware preinstalled from the factory. Prior to the purchase and installation of the EA4500 Router I replaced my old Motorola SurfBoard SB6120 DOCSIS 3.0 Cable Modem with a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem. My old Linksys E2000 Router worked perfectly with the SB6141, with the exception that the E2000 wasn’t IPv6 enabled, but does have 10/100/1000Base-T Ethernet (RJ-45) and Internet ports.
The EA4500 has been installed for about 10 days and seems to have improved local network speeds and I don’t seem to be having any Internet connectivity issues. However, there are some disturbing issues with the EA4500 and the AE3000 I purchased. There are 11 devices connected through the Router; a Dell Desktop (wireless with the AE3000), a Dell Desktop (Ethernet), a Dell Laptop (wireless), 2 Canon Printers (1 Ethernet and 1 Wireless), 2 Western Digital 1TB MyBookLive Network Drives (both Ethernet), a WD TV Live Streaming Media Player (wireless), an Apple TV media player (wireless), an iPad (wireless), and an Android Smartphone (wireless).
Issue 1 – The Linksys Smart Wi-Fi interface appears to be unreliable at times!!! I’ve read about this problem here on the Community involving the EA6500, so I don’t know if this is a Linksys Server issue, as suggested in a few responses, or a bug in the Router firmware, or defective hardware. However, when the interface locks up, it can’t be accessed from a wireless or wired connection. Usually, powering down the Router and then powering it back up and restart will allow it to function again. However, at times before the interface completely locks up it shows either just a white screen or the security screen will show no firewall features enabled. This is a little scary, so I’ll do a complete reset and setup; this is becoming a pain in the rear!!!!! Is there any hope for this being fixed, in this Router, not the next generation??????????
Issue 2 - All of my network devices show up in the Router’s Device List. Except for the Apple devices they also show up, when they are online, in Windows 7 Explorer under Network and when you click on Network they are correctly displayed as Computers, Media Devices, Network Infrastructure, or Storage. However, when you click on “Open Network and Sharing Center” and then click on “See Full Map”; it fails with the response “Windows cannot create the network map. Responses from other devices on the network are delayed or there is an incompatible router on the network”; no device map is shown. When I follow the link for more information, the only thing that stands out is “A device on the network, such as a hub or switch, is not working properly or is not compatible with the Link Layer Topology Discovery (LLTD) protocol, which Windows uses to create the map. To fix this problem, disable the device, turn it off, or remove it from your network”. All of my network devices showed up on the Network Map with the old E2000. This issue is the same on all of my computers, either wired or wireless. Any known solutions for this, or is it as Windows suggests; an incompatible Router????
Thanks in advance for any insight or solutions. With the issues I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.thebluemamba_24; Thank you for your suggestion; I finally found time yesterday to perform an extensive evaluation before I return the Router. However, rather than trying to add devices manually, my rationale was if the EA4500 can’t process them correctly, automatically, it needs to be returned anyway, so I added devices normally letting the device an Router handle the process.
In thinking through this issue, all devices on our network are detected and identified by Windows Explorer on Windows 7 computers; except of course the Apple and Android devices (Apple TV, iPad, and Smartphone). So, I wondered if one of those three devices being added to the Router’s device list was somehow causing issues or interfering with Windows 7’s ability to generate a Network Map. Therefore, my approach was to turn off or disable all devices on our network, reset the Router to factory defaults, reestablish the Router to my custom Home Network configuration using a Windows 7 PC that has LAN and Wireless access to the Router, then add one device at a time and check with each addition to see if Windows 7 could still generate a Network Map.
With the Router reset and reestablishment complete; I began the process of adding one device at a time and checking to see if a Network Map was being generated. What I discovered was when a recent addition to the network, a Western Digital WD TV Live Streaming Media Player, was connected (wirelessly), Windows 7 could no longer generate the Network Map and the failure was consistent. The only way to get the Network Map to work again was to remove power from the WD TV Live, although it remained in the EA4500’s Device List; simply turning it off didn’t help. Since I’d originally witnessed the Windows 7 Network Map working with the Linksys E2000 Router that the EA4500 replaced, I decided to test the WD TV Live with that Router. It worked initially, but it failed consistently after the first success. Interestingly, the failure indication was a little different, but nevertheless generation of the Network Map failed.
I’ve tried changing a few settings on the EA4500 as well as the WD TV Live, but nothing helped. There was a recent firmware update to the WD TV Live, so I might try rolling back the firmware to see if it makes a difference.
The Network Map issue might very well be an issue with the WD TV Live, not the Router, but after reading many threads on this Community I have reservations that the problems I’m experiencing with the Smart interface lockup will be fixed. I suspect new emerging replacement products will be the focus and these older products will be abandoned and no more firmware fixes will be forthcoming and I don’t want to spend more money for a new product just to fix old problems and get something that works properly. The Network Map issue is troublesome, but the lockup of the Router’s “Linksys Smart Wi-Fi” interface is a serious matter to me. It appears that once it locks up, the only way to correct it is a power off restart; not practical if you’re traveling and trying to access settings remotely; the selling point for this feature.
Given the problems I’m experiencing with the EA4500 and AE3000, I guess I’ll return them. Too bad, because otherwise the EA4500 seems like it’s a good Router. I’ve been brand loyal since the Linksys WRT54G came out, but after reading this Community and with my personal experience with the EA4500 and AE3000, now I’ll probably give the NETGEAR N900 equivalents a try. -
EP6 sp12 Performance Issue, Need help to improve performance
We have a Portal development environment with EP6.0 sp12.
What we are experiencing is performance issue, It's not extremely slow, but slow compared to normal ( compared to our prod box). For example, after putting the username and password and clicking the <Log on> Button it's taking more than 10 secs for the first home page to appear. Also currently we have hooked the Portal with 3 xAPPS system and one BW system. The time taken for a BW query to appear ( with selection screen) is also more than 10 secs. However access to one other xAPPS is comparatively faster.
Do we have a simple to use guide( Not a very elaborate one) with step by step guidance to immediately improve the performance of the Portal.
Simple guide, easy to implement, with immediate effect is what we are looking for in the short term
Thanks
ArunabhaHi Eric,
I have searched but didn't find the Portal Tuning and Optimization Guide as you have suggested, Can you help to find this.
Subrato,
This is good and I would obviously read through this, The issue here is this is only for Network.
But do you know any other guide, which as very basic ( may be 10 steps) and show step by step the process, it would be very helpful. I already have some information from the thread Portal Performance - page loads slow, client cache reset/cleared too often
But really looking for answer ( steps to do it quickly and effectively) instead of list of various guides.
It would be very helpful if you or anybody( who has actually done some performance tuning) can send a basic list of steps that I can do immediately, instead of reading through these large guides.
I know I am looking for a shortcut, but this is the need of the hour.
Thanks

Performance issues since upgrade
I am on a late 2011 MacBook Pro and am having severs performance issues since upgrading to Mavericks. I fear my issues may be related to company installed anti-virus (which I cannot remove), but I was hoping someone could look over my EtreCheck for other potential solutions.
One really odd issue I am having, which I cannot seem to find good information for on Google, is at least 4-5 times a day my Mac just stops. No beach ball, no anything, for about 1-5 minutes. Then it's fine. Maybe just me grasping at straws, but it seems related to a when webpage loads a bunch of images? I always use Safari btw, but testing other browsers, like Chrome & Firefox, it happens as well.
I have also removed TotalFinder and have noticed no improvement and still have the above issue.
Thanks in advance!
Here is my EtreCheck:
