USB 3.0 + SSD + W510 = Low Performance???

Hey everyone-
I just purchased this W510, and I love it!
I also purchased a Corsair F120 120GB SSD and a Patriot Gauntlet USB 3.0 enclosure for storage of files. In running initial tests on this drive with HD Tune Pro, I found the following:
1) Sequential read: Internal HDD starts off at ~97 MB/sec and tapers off to ~60% of that speed as the test runs out to the edge of the platter. SSD, on the other hand, is a constant ~94 MB/sec or so, and equals the performance of the HDD when the HDD is about at the 100GB mark (500GB drive).
2) Sequential write: Internal HDD is still just under 100 MB/sec to start, but the SSD only delivers about 50 MB/sec.
Now this is a newer Sandforce SSD capable of over 250 MB/sec transfer rates, so I know the bottleneck isn't the SSD. Also, I read test writeup here: http://www.guru3d.com/article/msi-star-usb-3-controller-test/9 where a USB 3.0 card installed in a desktop PC performed MUCH better with an external SSD connected, at almost twice the read speed and 3x the write speed that I experienced, using the same test software. Finally, let's assume the SSD is limited to the same throughput as the internal hard drive for some odd reason... why would the write speed to the SSD be cut in half? In any case, I would expect higher performance from a 250 MB/sec drive on a 5Gigabit interface connected to a PCI bus vs. an HDD capable of around 100 MB/sec on a 3 gigabit interface on the same PCI bus.
Any ideas on what might be going on here? Can I actually expect higher performance? At this point, I'd be happy to match the performance of the internal hard drive!
My USB 3.0 controller driver is version 1.0.19.0, which I believe is current.

Very Low performance Firewire

Hi
First.. sorry for Bad translating.
i notes very low performance of my FW800/400 (i think after EFI/SMC Firmware Update)
FW800/400 More slowly the USB2 and FW800 cannot see External Devices that working fine with my macbook pro.

Hey Noorldin,
I think I have a similar problem. I have always had some issues with the ports (owned the MacPro since the first month it came out) but several months ago things took a turn for the worse. External harddrives no longer work properly. USB drives won't mount, firewire drives will mount but the transfer rate is roughly 1MB a sec and after ~10 MB I get an error and the transfer stops. Other peripherals work for the most part but not well. My external usb microphone will not stop receiving audio signals when turned off and my canon HV20 drops frames during transfers. My awesome fujitsu scansnap scanner, printer, and usb mouse transmitter all work fine though. I used to be able to play many 1080p videos at the same time, now I can not play one without frames dropping even when booted into a new clean internal HDD. The MacPro will only sleep if I manually set it to sleep. The autosleep feature will have the internal hdds spinning up and down all night.
I spent 20 min on hold to get an Apple rep and then 47 min on hold to get an Apple Specialist. The specialist was very kind and tried many things with me. In the end, the specialist concluded that my Logic board or CPUs were most likely bad and that I should get them tested and possibly replaced. You may need the same.
One weird thing I tried just the other night was to unplug all USB and Firewire devices, including my 30 in display and wireless mouse hub, and then I plugged in just one firewire hdd. It worked fine!? So, I will continue testing on my own for a while and let you know what I find out from my tests or from the Apple repairs, as I have only seen one other person with an issue like mine and what I believe might be yours too. I have seen many issues with the front ports not working right though.

Macbook Pro mid 2012 HDD clicking and low performance

Hello, everybody!
I have a question about the HDD, I think it's failing or it's very close to failing.
From the moment I bought my Macbook Pro 13" mid 2012 model I noticed quite low performance and also very disturbing sound of the HDD clicking, even when I don't touch the laptop. Running Disk Utility check and Apple Diagnostics became my favorite pastime, but it showed no sign of HDD (or other kind of) failure.
The smartcl shows the following:

Also I've noticed that the disk read operation takes more than (I believe) it should. For example, when I turn the laptop on and it was in the hibernation mode, it restores quite quickly and shows the login screen, but it's actually impossible to enter anything there, it just doesn't respond to keyboard or mouse input. By the time the login screen times out I am still unable to enter anything, and it goes back to sleep, and the story repeats.
More to it, most of the apps take ages to start. Preview starts in 5-10 seconds.
I thought it shouldn't be a software problem, since I formatted the drive and installed a fresh copy of OS X just two weeks ago.
So I went to the reseller I bought it from (Compustore here in Germany) and asked to check the laptop. They did, and told me everything was fine with it.
Is it indeed the normal behavior of Macbooks? I don't have anything to compare to, it's my first Mac, but I'm really far from being satisfied with it. Any suggestions on how to fix this?
Thank you in advance for any suggestions,
Elijah.

Is it indeed the normal behavior of Macbooks?
No, of course not. It is very abnormal and the reseller's conclusion that everything is fine is obviously incorrect.
I have no explanation for the fact that Apple Diagnostics nor Disk Utility indicates a fault, but if the problem remained unchanged after taking the extreme measure of completely erasing the hard disk and installing OS X as you explained, then the only remaining cause is a hardware fault that has eluded all attempts to detect it.
I formatted the drive and installed a fresh copy of OS X just two weeks ago.
Confim the problems remained immediately after those actions and prior to installing any other software. The most common explanation for the behaviour you describe is the presence of any number of ill-conceived "anti-virus" or "cleanup" utilities.
If you described the problem and your attempts to rectify it accurately, then the reseller did not perform adequate diagnostic testing, or they are being deliberately deceitful, or they are simply incompetent.

How to know if system is running in 40W low performance mode ?

I experienced the same problem than described in this topic: lower performance with charger than with battery!
(But I had set everything on Maximum Performance both in BIOS and in Windows's Power settings, so I think everything was done on software-side).
How to know if the system runs with lower performance (is it a 40W max mode? btw how did you know it is called "40W mode" ? I saw this figure nowhere else than in the mentioned-above topic) , except using a soft to do some benchmarking? Is there a place in BIOS (I didn't find!) ?

Hi,

I see that Leopard support 64, but didn't find if it was actually running in 64.

Welcome to Apple Discussions:
if your computer is 64-bit, Leopard is running in the 64-bit mode. There are a few caveats about this but basically this is the case.

Low performance issue with EPM Add-in SP16 using Office Excel 2010

We are having low performance issues using the EPM Excel Add-in SP16 with Excel 2010 and Windows 7
The same reports using Excel 2007 (Windows 7 or XP) run OK
Anyone with the same issue?
Thanks

Solved. It's a known issue. The solution, as provided by SAP Support is:
Dear Customer,
This problem may relate to a known issue, which happens on EPM Add-in
with Excel 2010 when zoom is NOT 100%.
to verify this, could please please try to set the zoom to 100% for
your EPM report in question. and observe if refreshing performance is
recovered?.
Quite annoying, isn't it?

Low performance in OBIEE11g

How I can improve the performance of my OBIEE 11g, specifically with the Publisher (there´s available the configuration tags for this version?). Also another question is to know the limit of registries to show in the report, this because I had one with too many information that doesn´t show correctly the information.
Thanks in advanced.
Greetings.

JSPDynPage and PageProcessorComponent low performance

Hi all,
We are having troubles with the implementation some JSP applications in EP 6.0 SP2.
We have used "PageProcessorComponent" as the main class for the Component, and JSPDynPage for the class to invoke the jsp pages.
The applications work fine but too slow compare to other componentes that use "AbstractPortalComponent" and
IResource form = request.getResource(IResource.JSP, "pagelet/form.jsp");
response.include(request, form);
To invoke the jsp Page.
Why is it possible this low performance in runtime?
Thank you

DID you try this approach
package com.cts.anand;
import com.sapportals.portal.prt.component.*;
public class BeanDyn extends PageProcessorComponent {
public DynPage getPage(){
    return new BeanDynDynPage();
public static class BeanDynDynPage extends JSPDynPage{
    public void doInitialization(){
     public void clientSave(Event event) {

Select single to RSEG with very low performance

Hello experts,
We have recently upgraded our sap basis from 701 to 740 and we are experiencing a very low performance with the following abap instruction:
select single * from rseg into lw_rseg where ebeln = lw_output-pedido and
ebelp = lw_output-item and
kschl = lw_output-kschl.
Could it be anything from the upgrade?
Any suggestions?
If we change the "*" for only one field of the RSEG table, would the improvement in te performance be significant?
Thank you.
Best regards,
Raquel Oliveira

Hi, Raquel!
In SELECT statement you are not using the key fields for RSEG table.
Replacing "*" by a single field won't do the trick.
In our system we've got a table index on EBELN and EBELP fields in RSEG and it helps a lot.
In case you don't want to set additional indexes you can find all incoming invoices for the purchasing document items in EKBE table and then go to RSEG having BELNR, GJAHR and BUZEI fields.
If you already have table index on RSEG with EBELN & EBELP fields - you can trace SQL statement in ST05 and check whether it uses the index.
And apart from that - anything can be from upgrade

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
#Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''.
Now, a new tab containing your troubleshooting information should open.
#At the top right corner of the page, you should see a button that says "Reset Firefox"[[Image:Button reset]]. Click on it.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Very Low Performance And Stability gaps

Hello, first of all, sorry me because of my low level english.
I have recent bought new pieces for my sistem, my older CPU was a Duron 1300 (overclocked 1400) in a Gigabyte Ga-7zxr mobo with 512 SDRAM 133 mem.
I choosed a MSI mobo, the KT6 delta (sr), a 2600 XP+ and 512 DDR 333, with no knowed fabricant.
I get a lower performance in my new system than the older, isn't normal.
I have so much questions, please reply me so much you can, i'm getting crazy
I've read in other posts some specifications about Amp' consume in the mobo.
Where can i see it? Say me and i'll post it.
My 2600 xp+ is the model 8 (not the actual 10), it have 256 Kb cache instead 512 and run over 200 mhz over the model 10. 167 x 12.5.
(wrong forum?, could be, dont reply me to it if you think i should no make this question)
Well, go with mobo problems.
My monitor refresh (like if I change the resolution) so often, I don't know why.
In the dxdiag, in the 3D test, i get a cube no well showing, i only see a bad image, like if the cube is turning hyper velocity.
In all sandra test i have a performance according with my system, but when i get to ride games, i get low performance than in my older system
My mem isn't kingston and isn't of any knowed mark. I only could to get kingstom memory instead, i would do it? is really so recomended?

Too much question, really, i know.
I'm thinking to install a CPU Cooler in the mobo chipset and in the RADEON chipset also, must i do it?
All my CPU details are below.
Thanks for all.!!!!

The model 8 Of AMD AThlon XP is a 333 FPU. I've read it in AMD and other pages.

May i have to change the mem to a kingstom mem?

Macbook pro low performance

I'd written about this topic earlier that my mbp had low performance. There were missing packages in library receipts and i moved the missing packages and it's performance immediately went to top. But 3 or 4 days before i noticed that its performance got low as before. I run xbench and the result was awful compared before. I took it to service and they told me that nothing is wrong with the hardware and software and reinstalled osx. But the result is low as the same. What should i do? Is anybody facing that kind of a problem. And the machine gives an error message 4SNS/1/40000000:TBOT what does it mean. Thank you for your replies

Hi mreavsar;
How much free space do you have on your hard drive?
Low free space can cause two problems. First it can cause slow performance. It can also cause file corruption which in turn can cause more poor performance and other strange problems.

Low performance vs EPG

I have installed Apex Listener+Glassfish on APEX 4.0.1. Everything is working fine, but firebug shows low performance. For example: the same ajax call performing about 250-350ms with EPG versus 390-430ms with Apex Listener. What am I doing wrong?
Im also wondering how to properly set-up Cache Files in Apex Listener.

Hello haXbat,
it's odd that you get such a high supplement for round trip times when running the Listener on the same machine as your database. Do you see any heavy load on your server that could explain that? Or is your unit "ms" micro seconds instead of milli seconds? I wouldn't say it's bad performance then. ;)
If you just use "plain APEX", there should be no need to use the Listener instead of EPG.
But the APEX Listener will get additional features with upcoming releases which won't be available for EPG. On the other hand, there currently also exist features you can configure on EPG that aren't available on the APEX Listener.
So I'd at least test with the Listener from time to time to be sure everything will run as expected in case you plan to run with the Listener in your production environment.
