PCMCIA gigabit cards are poor performance with lenovo n100

Hello,
I have a lenovo n100 and I tried two pcmcia gigabit cards (Dlink DGE 660TD and TRENDnet TEG-PCBUSR) with very poor performance. I tested with iperf (cat6 cable with Siemens Sinergie S300 server) and Windows, linux, normal config, tunned tcp parameters, the outcome is always the same, 200Mbits upload and 76Mbits for download.
Any sugestion?
Kind regards,
André P. Muga

There is two type of PCMCIA, one is running at 16 bit another is running through 32 bit.
You can achieve the gigabit requirements quite comfortably with the 32 bit, but i think the 16 bit version is not going to be enough for the gigabit ethernet.
Running at Mhz??? I don't understand how that is anything to with data bandwidth.
Both are pcmcia2, 32 bits, gigabit ethernet, full duplex, cards.
The peak transfer rate is calculated by <bus speed MHz> * <bus width> = <Mbps>
Example:
Bus speed 33MHz, Bus width: 32bits
33 * 32 = 1056 Mbps or 132MBps
Bus speed 667MHz, Bus width: 32bits
667 * 32 = 21344Mbps or 2668MBps
The lenovo N100 has a 32 bit bus with 667MHz.... no limitation here.

Non jdriver poor performance with oracle cluster

Hi,
we decided to implement batch input and went from Weblogic Jdriver to Oracle Thin 9.2.0.6.
Our system are a Weblogic 6.1 cluster and an Oracle 8.1.7 cluster.
Problem is .. with the new Oracle drivers our actions on the webapp takes twice as long as with Jdriver. We also tried OCI .. same problem. We switched to a single Oracle 8.1.7 database .. and it worked again with all thick or thin drivers.
So .. new Oracle drivers with oracle cluster result in bad performance, but with Jdriver it works perfectly. Does sb. see some connection?
I mean .. it works with Jdriver .. so it cant be the database, huh? But we really tried with every JDBC possibility! In fact .. we need batch input. Advise is very appreciated =].
Thanx for help!!

Thx for quick replys. I forget to mention .. we also tried 10g v10.1.0.3 from instantclient yesterday.
I have to agree with Joe. It was really fast on the single machine database .. but we had same poor performance with cluster-db. It is frustrating. Specially if u consider that the Jdriver (which works perfectly in every combination) is 4 years old!
Ok .. we got this scenario, with our appPage CustomerOverview (intensiv db-loading) (sorry.. no real profiling, time is taken with pc watch) (Oracle is 8.1.7 OPS patch level1) ...
WL6.1_Cluster + Jdriver6.1 + DB_cluster => 4sec
WL6.1_Cluster + Jdriver6.1 + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_single => 4sec
WL6.1_Cluster + Ora8.1.7 OCI + DB_cluster => 8-10sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_single => 4sec
WL6.1_Cluster + Ora9.2.0.5/6 thin + DB_cluster => 8sec
WL6.1_Cluster + Ora10.1.0.3 thin + DB_single => 2-4sec (awesome fast!!)
WL6.1_Cluster + Ora10.1.0.3 thin + DB_cluster => 6-8sec
Customers rough us up, because they cannot mass order via batch input. Any suggestions how to solve this issue is very appreciated.
TIA

else. I would try the latest

It's much faster than any 9.X

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.
http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATAFW800_FW400USB
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:
http://discussions.apple.com/thread.jspa?messageID=5564509#5564509
FireWire compared to USB. You will find that FireWire 400 is faster than USB 2.0 when used for a external harddrive connection.

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
/Frank
Edited by: Mads Frank on Feb 1, 2010 9:41 PM

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

Poor performance with Oracle Spatial when spatial query invoked remotely

Is anyone aware of any problems with Oracle Spatial (10.2.0.4 with patches 6989483 and 7003151 on Red Hat Linux 4) which might explain why a spatial query (SDO_WITHIN_DISTANCE) would perform 20 times worse when it was invoked remotely from another computer (using SQLplus) vs. invoking the very same query from the database server itself (also using SQLplus)?
Does Oracle Spatial have any known problems with servers which use SAN disk storage? That is the primary difference between a server in which I see this poor performance and another server where the performance is fine.
Thank you in advance for any thoughts you might share.

OK, that's clearer.
Are you sure it is the SQL inside the procedure that is causing the problem? To check, try extracting the SQL from inside the procedure and run it in SQLPLUS with
set autotrace on
set timing on
SELECT ....If the plans and performance are the same then it may be something inside the procedure itself.
Have you profiled the procedure? Here is an example of how to do it:
Prompt Firstly, create PL/SQL profiler table
@$ORACLE_HOME/rdbms/admin/proftab.sql

Poor performance with small files on Xsan volume

Since I'm running on Xsan for with network users and server shares, I have various problems.
Users complaining on slow logins, Word files that have saving errors. For the Word problem, there are a lot tricks like .TemporaryItems with acl.
But I think there's another reason. My mobile home users are not yet using the new home server with mobile homes. Today I migrated my own account to the new server en syncing is very slow on files from my iCal server and mail archive.
So I did a test on the servers that are connected to the san. The backup servers has the san volume mounted and some old Xraids for backup storage. If I duplicate my iCal folder (8000 files) it takes 8 minutes in the Xsan volume. On an Xraid, less than 30 seconds. If I duplicate 1 2.5GB diskimage file on the san volume, it does it in less than 10 seconds.
My Xsan setup:
All Intel Xserves
1 MD server dedicated (4GB Atto FC)
1 OD server and server shares (and backup MD controller) (4GB Atto FC)
1 home folder server (4GB Atto FC)
1 backup server (also MD backup controller) (4GB Apple FC card)
2 Promise Vtraks with 16X 750 GB disks
1 MD lun (2disks mirrored) (Own FC controller)
2 Data luns (8.87 TB each lun) (Each own FC controller)
Xsan setup is done with configuration for home directories.
Block allocation size: 8kb Round Robin
Separate ethernet metadata network.
I hope someone can give me some pointers.
Patrick

I have the same issue and it is killing our iCal Server performance.
My question would be, can you edit an XSAN Volume without destroying the data?
There is one setting that I think might ease the pressure... in the Cache Settings (Volumes -> <Right-Click Volume> -> Edit Volume Settings)
Would increasing the amount of Cache help? Would it destroy the data?!?!?

Poor Performance with Converged Fabrics

Hi Guys,
I'm having some serious performance issues with Converged Fabrics in my Windows Server 2012 R2 lab. I'm planning on creating a Hyper-V cluster with 3 nodes. I've built the first node, building and installing/configuring OS and Hyper-V pretty straight forward.
My issue is with Converged Fabrics, I'm absolutely getting very slow performance in the sense of managing the OS, Remote Desktop connections taking very long and eventually times out. Server unable to find a writable domain controller due to slow performance.
If I remove the converged fabric everything is awesome, works as expected. Please note that the cluster hasn't even been built yet and experiencing this poor performance.
Here is my server configuration:
OS: Windows Server 2012 R2
RAM: 64GB
Processor: Intel I7 Gen 3
NICS: 2 X Intel I350-T2 Adapters, supporting SRIOV/VMQ
Updates: All the latest updates applied
Storage:
Windows Server 2012 R2 Storage Spaces
Synology DS1813+
Updates: All the latest updates applied
Below is the script I've written to automate the entire process.

I would really like to know why I'm getting absolutely poor performance. Any help on this would be most appreciated.

I didn't parse the entire script, but a few things stand out.
SR-IOV and teaming don't mix. The purpose of SR-IOV is to go straight from the virtual machine into the physical adapter and back, completely bypassing the entire Hyper-V virtual switch and everything that goes with it. Team or SR-IOV.
You're adding DNS servers to adapters that don't need them. Inbound traffic is going to be confused, to say the least. The only adapter that should have DNS addresses is the management adapter. For all others, you should run Set-DnsClient -RegisterThisConnectionsAddress
$false.
I don't know that I'm reading your script correctly, but it appears you have multiple adapters set up for management. That won't end well.
It also looks like you have QoS weights that total over 100. That also won't end well.
I don't know that these explain poor performance like you're describing, though. It could just be that you're a victim of network adapters/drivers that have poor support for VMQ. Bad VMQ is worse than no VMQ. But, VMQ+teaming+SR-IOV sounds like recipe for
heartache to me, so I'd start with that.

Poor Performance with 10.1

I'm on a windows xp sp 3 machine with an x800 xt pe graphics card using the latest catalyst drivers from Ati. Ever since I updated flash, I'm getting very poor performance during 720p with acceleration enabled. I'm also getting bad performance when it's disabled. Is there an issue with the 10.2 legacy (ati) drivers not enabling hardware acceleration with 10.1 flash?
BTW I went back to using 10.0.42.34 flash and everything is running fine again.

I've also noticed poor performance since installing the 10.1 plugin. Not just in HD video etc, but in general use. So much for "improved performance"...
No idea on solutions at this stage - In the process of downgrading to previous version to see if that fixes my problems

Poor performance with Acrobat Pro 9

Hello,
Acrobat Pro 9 has begun to run very slowly. When checking review comments, simply filling in a check box for an edit can take a solid ten-count. If I take the same file and open it on another computer, it runs fine. I use the shared review function for some documents, and the enable commenting function for others. If I open Acrobat by holding the shift key so that no plug ins are run, the program functions fairly well, but then I can't use any of the features provided through the plugins.
This is getting to be a very serious problem. I'd appreciate some help with it. Thanks.

The 2013 Mac Pro Quad-Core with dual FirePro D300 GPUs beat the 2013 iMac Quad-Core i7 with the single GeForce GTX 780M GPU in 8 out of 12 of the tests featured above. However, it only 'blew away' the iMac in three GPU intensive tests -- two of which utilize the dual GPUs.
http://barefeats.com/tube17.html
LuxMark is one of the few OpenCL benchmarks that uses multiple GPUs. So we used it in our last graph to highlight the advantage of the 'late 2013' Mac Pro's slowest pair of GPUs (FirePro D300s). It obliterates the iMac's single GPU, but a 2010 Mac Pro tower with a really strong AMD GPU like the 7970 (running only on internal factory PCIe power feeds) comes close. I predict that the dual D700s in the top 2013 Mac Pro models will reach or exceed 4000KSamples/sec.
a comparison of all models from 4-Core to 12-Core using Pro Apps. And a 4-Core iMac is thrown in for good measure.

I cannot point to a good test and review of issues with Adobe apps and nMP due to poor AMD drivers but I think you can find those.
Here is a jump into some, and I think you would find more over here:

Not sure if this issue went away or not, if 10,9.5 helped (it should have) or perhaps try a clean install (maybe external device if not backup + erase & install) There are enough issues with importing from another system using Migration Assistant to avoid that, but none with Setup Assistant (go figure why it has bugs... still).

Poor performance with SVM mirrored stripes

Problem: poor write performance with configuration included below. Before attaching striped subdevices to mirror, they write/read very fast (>20,000 kw/s according to iostat), but after mirror attachment and sync performance is <2,000 kw/s. I've got standard SVM-mirrored root disks that perform at > 20,000 kw/s, so something seems odd. Any help would be greatly appreciated.

I have the same issue and it is killing our iCal Server performance.
My question would be, can you edit an XSAN Volume without destroying the data?
There is one setting that I think might ease the pressure... in the Cache Settings (Volumes -> <Right-Click Volume> -> Edit Volume Settings)
Would increasing the amount of Cache help? Would it destroy the data?!?!?

Photoshop laggy, poor performance with GPU enabled

I'm using Photoshop CS6 for some time now. I had enabled GPU usage earlier and I remember that Photoshop ran absolutely smoothly without and lag what-so-ever. This morning, all of a sudden, it has become extermely laggy. I don't understand the reason behind this. This had happened to me before as well but it became alright after a few days. This also happened to me once while using Photoshop CS5. I didn't install any plugin and didn't change any software. I also want to point out that I had 13.4 driver version when Photoshop was working fine, and now too I have the same driver version.
CPU: AMD Phenom II X4 955
Memory: 6 GB
Free storage: 8 GB
GPU: ATI Radeon HD 5850

Poor performance with Yosemite and early 2009 Mac Pro

I have an early 2009 Mac Pro with the following specs:
- 2.66 GHz Quad Core Intel Xeon
- 10 GB of 1066 MHz RAM
- NVidia GeForce GT 120 512 MB
- 256 MB solid state drive for my system partition
- Two monitors connected, each at 1680x1050 resolution
Back when I was running OS X 10.7 or 10.8 I found that for every day tasks the performance using my computer was adequate. However, starting around 10.9, and even worse since upgrading to 10.10, thinks have gotten painfully slow. To give an example, activating Mission Control can take upwards of four seconds, with the animation being very choppy. Changing tabs on a Finder window can take two seconds for the switch to happen. Just switching between different windows, it can take several seconds for a window to activate. It's gotten to the point where I'm having difficulty working. So I'm thinking of upgrading some of my hardware.
Given my specs the weakest link seems to be my graphics card, and all of these issues do seem to be related to graphics. So my questions are:
- Do you think upgrading my graphics card will substantially improve things, and is there anything else I should upgrade?
- Is this slowness just the result of the computer being nearly six years old, and no upgrades will really improve things that much?
Thanks in advance!

Between Setup Assistant, and your existing system "untouched" (or use CCC if say you want to use an existing SSD for the system) there is no reason it should be a lot of work setting up. Have you ever used Migration or Setup? it has also gotten better.
Also, having 10.9.5 on another drive and running DU - and TRIM _now_ would be helpful.
Looking at just what gremlins you have running around inside your current system is not bad but.... sometimes the "long road" turns a shortcut into a dead end, and avoiding doing what seems the long road and hardest gets you where you want to go: a solid stable system.
Less is more. Most systems have more than needed and they get in the way and can cause trouble. Even handy "widgets" and those things that monitor system functions, even disk status. Which is why I like seeing a separate small system maintenance volume just for the weekly checkup. 30GB is more than enough so just slice out a partition somewhere - on another drive/device.
Those things, more so than and a lot cheaper than a new GPU. If your SSD is two years old, the 840 EVO from Samsung is down under $120 for 250GB, or use one for Lightroom / Aperture / iPhoto or scratch.
One person was complaining about sluggish window issue and thought it was the driver. Turned out It happened in ONE APP, not everywhere - very telling - and the app in question needs update. Adobe updated CC (for Windows) last month to finally support dual Dxx and some of the newer AMD GPUs - can the mac be far behind?
10GB RAM? that would not be 3 x 4GB or any combination using triple channel memory.

Poor performance with x800xt & Neo 2 Pt.

First, my problem is very similar to the one found at slow 6800gt , however instead of a 6800gt I have an X800xt. Basically, my performance in 3dmark 03 is around 9,500 stock when it should be about 12,000 stock, and 3dmark 05/ x benchmark is slower than people with very similar systems. (1 gig ram, A64 3200+, x800xt). Now, sometime about a year ago I had the same problem but fixed it by installing Chipset drivers. However, since I had to get an rma replacement for my video card I had to reinstall everything and now the problem is back.
I would use the same method of fixing as the other thread, except that thread deals with nvidia and conflicts with coolbits/detonator, neither of which I have installed on my computer with ATI. I have tried numerous drivers and reformatting, but it still seems to persistently score low. Any obvious things or tricky things I may have forgotten to do since a clean install?

Hi Fadi,
Yes, for normal day to day operations, you want to be in CBO mode. Just ensure your schema and dictionary stats are current.
I am currently running the following script as sysdba every month or so depending on how much your instance is growing, despite the fact Oracle advises running adstats.sql in restricted mode (need downtime for that):
cat analyze10g.sql
!date
exec dbms_stats.gather_schema_stats('SYSTEM',options=>'GATHER', estimate_percent
=> 100, method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
!date
exec dbms_stats.gather_schema_stats('SYS',options=>'GATHER', estimate_percent =>
100, method_opt => 'FOR ALL COLUMNS SIZE AUTO', cascade => TRUE);
!date
exec dbms_stats.gather_fixed_objects_stats();
!date
commit;
exec dbms_stats.DELETE_TABLE_STATS('SYS','X$KCCRSR');
exec dbms_stats.LOCK_TABLE_STATS('SYS','X$KCCRSR');
commit;
Also make sure parallel_max_servers is set to 2x (number of CPU cores) if you have more than 4 available. I bumped mine from 8 to 48 along with adding large_pool_size and saw some huge gains in Gather Schema Stats timing, especially if you have many large tables.

Poor Performance with BouncyCastle provider in Oracle JVM

When I run the BouncyCastle provider with Oracle JVM in the database, it runs poorly on the first call, but second and subsequent calls aren't so bad. What options do I have:
1. Ncomp? If I go this route, does someone have the necessary scripts and suggestions for using an open source/free C compiler rather than Visual Studio?
2. Is there a way that I can "pin" these java classes/objects in memory? (classes from BouncyCastle) How would I know what classes to PIN? I can run an execution profiler against it on the client, but will that tell me everything needed to pin?
BTW, here's the results of a performance test of two consecutive runs with some embedded System.out.println calls for the timestamping:
Here's the update.... Most of the time on initial call is taken to read the keystore (2.2 seconds) and then decrypt the card (~16 seconds)
