Poor server performance

I have a Lenovo ThinkServer RD440 running windows 2012 R2 with a RAID 10 running 3TB 7.2K drives using the builtin raid controller and the server performance is pitiful.I believe it is related to disk performance and we get very high Active Time % usually pegged at 100% and the Disk Queue length is usually above 6. Responce time(ms) is unusually high as well most around 70ms but C:\pagefile.sys is 1284ms.It is a file server but it does not get much use. I also run spiceworks and SEPM. Shutting down the services does not effect the active time or queue length. When i RDP the desktop frequency stops responding. I have contacted Lenovo's technical support and ran their hardware diagnostics and they state it has came back clean and would not provide further help...Anyone else have experienced this and have a possible solution?

I have recently upgraded my ipad mini to iOS 6.0.2 and still have poor wifi performance. My 3rd generation ipad works great on the same network. I have done all the resets I can think of but nothing helps. I would not have purchased the mini had I known.

On the same wifi network, third generation ipad, iphone4s and MacBook Pro work just fine. The ipad mini often can not connect with the mail server and seems to hang a long time trying to open a web page. Had I known the mini had this kind of difficulty on wifi, I would have reconsidered my purchase. I have tried resetting the network and renewing the lease on the mini in addition. To completing the most current iOS upgrade. Still poor wifi performance. Unacceptable, in my opinion.

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

[SOLVED] Poor 2D performance of Radeon 7200 with newest xf86-video-ati

Today arrived new version (6.12.99) of ATI OSS driver (also new version of ati-dri 7.6, mesa 7.6 and xorg-server 1.7.1) Since that moment I'm experiencing poor 2D performance, especially in GIMP (scrooling of zoomed canvas). Also switching of virt. desktop where is bloated Java app. or fat Firefox instance result in poor render of screen (program renders by parts/semiwindows).
Here is some relevant infoozzzz:

BTW I'm not using Compiz. Has anyone an idea what could happen? In Glxgears I'm achieving 1200fps, but working with GIMP is laggy-horror.

DNS Server Performance

Hey!
I'm preparing my 70-410 exam
and would like to nkow some troubleshooting tips when it comes to DNS server performing slowly.
Thanks for your help in advance.

If your Mac is getting good speeds, but page loads are still low it certainly could be due to poor DNS performance.
I have been using 4.2.2.1 and 4.2.2.2 as my DNS for a few years and the performance was much better than those supplied by my ISP.
I have also fooled around with OpenDNS on my PC and it works nicely. I am happy with the performance on my Mac, so I have left it alone. You can get all the info you need on OpenDNS on their page found HERE.

Exchange 2013 CU7 server performance/outage issues.

Hi Forum,
We are constantly faced with incidents from users that the connections are lost with the exchange server. As a result, we hired a consultant to install an new Exchange 2013 environment based on the Microsoft, VM-Ware and NetApp best practices.
We are still having problems with performance issues. From the client prospective, the performance has not changed, weekly hangs are still happening and I’m at my wits end.
This is our configuration:
2 Windows Server 2012 R2 CAS and DB
VM with 4 vCpu, 16GB, 1 Vmxnet3, IPv6 disabled (the Microsoft way)
VM Ware 5.1 U1
Cluster without AAP
DB1 active on Server 1 (Datacenter 1 with 3 host cluster)
DB2 active on Server 2 (Datacenter 2 with 3 host cluster)
Veeam 8 Backup (Move-ActiveMailboxDatabase DB2 -ActivateOnServer Server1 , backup server 2 then Move-ActiveMailboxDatabase back to
Server2.
Exchange is in Online-Mode due to Citrix XD VDI clients.
1300 Mailboxes and 750 users.
NetApp with SATA disks. (1.5TB E: Vol for DB1/1.5TB F: Vol for DB2)
No archiving
Unlimited mailbox sizes.
The problems are:
If we migrate a non-Exchange VM in the same cluster or to\from the same host, this results in a 30 second to 5 min Outlook outage;
If we make both DB’s active on mail server 1 and reboot server 2, this results in a 30 second to 5 min Outlook outage;
If we make both DB’s active on mail server 1 and do a Veeam backup of server 2, sometimes one of the DB’s go back to server 1, on its own;
While monitoring we see that the w3wp.exe and the Microsoft.Exchange.Store.worker.exe are consuming most of the cpu and memory;
What can I do to solve the outages?
Tnx. Timotatty.

Hi Simon,<o:p></o:p>
Apparently we are using basic authentication which result in a FailingCode=401 as seen in the Event Log under Active Monitoring --> Probe Results from ECP and others. This
became apparent after reading this blog:
http://blogs.technet.com/b/ehlro/archive/2014/02/20/exchange-2013-managed-availability-healthset-troubleshooting.aspx<o:p></o:p>
We are now overriding some of the monitors which require Forms Based Authentication.<o:p></o:p>
Regarding the other 2 issues we have changed the licensing model for Veeam 8 to allow full throughput which will reduce the backup time and add compression.
The KEMP support team helped us by deselecting Use HTTP/1.1 under View/Modify Services --> ECP –> Modify --> Real Servers. This
now only flags a service (ECP or ActiveSync or OWA) as being down instead of an etire server should one component fail.<o:p></o:p>
I am satisfied but still not happy with the steps required to troubleshoot an Unhealthy Health Sets:<o:p></o:p>
Invoke-MonitoringProbe always returns with: WARNING: Could not find assembly or object type associated with monitor identity '<Healthe Set >\< Probe >'. Please ensure
that the given monitor identity exists on the server.
This makes it very difficult to troubleshoot
Unhealthy Health Sets.

BI Server performance too slow

Hi experts,
I am facing an issue, my OBIEE sits on a Unix Platform. And many time the server performance is too slow, when I check the processes, Java under Orabi user is using more than 50% of the CPU utilization. I need to find the root cause behind it, as it is the production system and is affecting many users.
Thanks in advance.

Thanks Prassu,
Yes the Server is performing too much calculations, but they are required as need to cache reports at daily level also,
I have an observation that the MAX_CACHE_ENTRY_SIZE [MAX_CACHE_ENTRY_SIZE = 1 MB;] parameter is set only for 1 MB, I can understand that if any query fetching more data than 1 MB will not be cached. But is there any chance that this will affect the server as well.
Thanks
MT

Poor Bluetooth performance with all aluminum Mac Pro

The all aluminum case for pre-mavericks Mac Pro is the primary reason for poor antenna performance of Bluetooth. Aluminum, being a good conductor, acts as a reflector of EMF forming what is known as a Faraday Cage, essentially trapping emissions within the box. Normally, holes drilled in the case would allow enough EMF to pass through the case but the hole size for transmission is directly proportional to the lowest frequency that will pass through easily. An example is the typical microwave oven where the window is actually a conducting sheet with small enough hole such that higher freq light waves pass easily through the sheet but lower frequency microwaves do not. Perhaps if the drive bay covers were made of plastic, transmission of the Bluetooth and wifi would be sufficient. One might carefully nibble a slot or two in the side door but this would surely invalidate any warranty and care would have to be taken not to get aluminum particles inside the computer. This would probably nullify any FCC approval of the machine due to clocking noise interference with other devices. The best approach would probably be a tuned waveguide that passes frequencies only around 2.4 GHz ~ 5 GHz through the case (very similar to the way tuned ports on audio speakers pass a band of frequencies needed to extend bass response). I'm sure Apple will have corrected this design flaw in the new Mac Pro introduced this year. If you have lots of time on your hands you can get a college level text on electromagnetics (Maxwell's Equations, etc.) and derive all the details but with a bit of experimenting and reading about tin can antenna mods to wireless routers you should be able to improve Bluetooth performance significantly.

Thanks for the suggestion. I will have to move my wireless home base station. It is on the same desk as my mini so much less than 5 feet away.

Poor 3G performance from Hutchinson 3 Service Provide at HK

any Hong Kong 3G iphone users experiencing poor 3G performance on Hutchinson 3 network? test my 3G iphone against original EDGE iphone at same spot on office floor, browsing to www.yahoo.com and the performance was marginally quicker than EDGE. after calling our service provide, being told that we were capped on network bandwidth of 7.2mbps but the real speed testing was around 0.3mbps.... this is unacceptable performance.
Apple - please speak to vendor, this is making your product look BAD.

Server Performance slow

Client has a NetWare 6.5 server SP 7 or last one put out. Lately the server performance would drop to almost half the speed it was running after about 3 hrs of up time, I cannot see anything that point to any module or hardware that is causing this.
The PRB are where they are suppose to be.
The Dirty Cache is 0%
The only thing I can see is in the Busiest thread on the Kernel screen there is a Server [numbered anywhere from 01 to 20] that shows up with some fairly large numbers for memory usage. What i'm trying to do is to nail this down to what the actual application/module is.
On other screens there are supended semaphore. Can anyone explain this to me?
Any help would be greatly appreciated.

Server Performance (TOP)

Hi,
I'm running an oracle process, which may hit the Server CPU performance & Memory Status.
How may I generate a server performance report every 30 minutes by default?
How this can be done with Linux server, HP-UX and AIX Server?
Thanks in advance

.....what does 'hit the Server CPU performance & memory status' mean?
>
How may I generate a server performance report every 30 minutes by default?on linux, which is what this forum is about, install the 'sysstat' rpm package.
when installed, it generates statistics every 10 minutes.
goto /var/log/sa, you'll see files called 'sa', followed by the day number of the month.
you can extract the performance data in these files using 'sar -f <safile>', and choose the switch for the statistics you want to see.

Report server performance

Does anybody know
(1) Any benchmarks available for report server performance
(2) How is report server performance during formatting. we
are generating reports through report server in.pdf file.
(3) Where can I find Report server sizing docuement
Regards

The reports team is working on this set of documentations.
The documentation will include benchmarks and tuning guide for the server.
Once they are ready for the 9i reports server, the team will publish it on OTN.
