Benchmarks if you're interested

I received my MacBook Pro on Friday and have been doing some benchmarks. Three benchmarking applications were used: GeekbenchPreview, XBench 1.2, and CineBench 9.5. Machines involved:
2.0 Ghz MBP w/1 GB RAM and 100 GB Toshiba 5400 RPM drive.
1.33 Ghz Quicksilver w/ATI 9800 Pro Video, 1.5 GB RAM, 60 GB Seagate 7200 RPM drive.
1.0 Ghz Ti Powerbook w/1.0 GB RAM and 60 GB Hitachi 7200 RPM drive.
1.5 Ghz Al Powerbook - configuration unknown. Info taken from Geekbench website.
The results are in a zipped file containing an Excel spreadsheet with the data and basic analysis of performance differences. You can download the archive from my website.

Thanks for the post, though I have thought this thru and have decided to wait-mainly because my 12" PB is just as great as the day I bought it!

I don't understand the thing you call live bookmarks never used it, and most forums I have used notify VIA E-mail not giving out my E-mail address information when a reply has been made to the thread in question.

So how do I get notified of updates in this forum? As I said: I don't understand the thing you call LIVE BOOKMARKS I have never used them, and most forums I have used notify VIA E-mail not giving out my E-mail address, or other private information when a reply has been made to the thread in question, so how do I get notified of updates in this forum?

If you are interested in the actual design data for the Xeon processor, go to the Intel site and the actual CPU part numbers are:

Xeon 12 core - E5.2697v2
I read that the CPU is easy to swap out but am sure something goes wrong at a certain point - even if solderedon they make material to absorb the solder, making your work area VERY clean.
My Question now is this, get an 8 core, then replace with 2 3.7 QUAD CHIPS, what would happen?
I also noticed that the 8 core Mac Pro is 3.0 when in fact they do have a 3.4 8 core chip, so 2 =16? Or if correct, wouldn't you be able to replace a QUAD CHIP WITH THAT? I;M SURE THEY ARE UO TO SOMETHING AS 1) WE HAVE SEEN NO AUDIO FPU OR PERHAPS I SHOULD CHECK OUT PC MAKERS WINDOWS machines for Sisoft Sandra "B-E-N-C-H-M-A-R-K-S" -
SOMETHINGS UP AND AM SURE WE'LL ALL BE PLEASED, AS the mac pro was announced Last year, barely made the December mark, then pushed to January, then February and now April.
Would rather wait and have it done correct than released to early only to have it benchmarked in audio and found to be slower in a few areas- - - the logical part of my brain is wondering what else I would have to swap out as I am sure it would run, and fine for a while, then, poof....
PEACE===AM SURE APPLE WILL BLOW US AWAY - they have to figure out how to increase the power for 150 watts or make the GPU work which in regard to FPU, I thought was NVIDIA?

Which one do you use?

I recently started asking myself which stability and stress program to use.
Theyre many, but i usually chose between those 3:
1.Stress prime 2004 by Johnny Lee
2.Super Pi by the japanese record breaking guys
3.the well known prime95 (which i dont like to use to test my machines).
prime 95 lacks information and details IMO but is reliable(at least thats what people say), and many people dont know how to use it at first sight(including me), asking themself what is s11t this for?
super pi does not take much time to complete the 32million task, so im not sure about its reliability.
and finally the one that i think is the best is the stress prime 2004 which i like the most, and the funcitons are there and it shows everything in details. the source is taken from prime95 but redone to give better results and details.
so c'mon you o/cers, which one do you prefer ? maybe you can suggest another good one from the rest which you find interesting and reliable!!
and pls no everest or sandra stress test suggestions.
good day

I use the following: http://www.7byte.com/index.php?page=hotcpu
Hot CPU pro is available in an evaluation version that doesn't perform all the tests but still has an accurate diagnostic and burn in mode.
I licensed for the full features and find it works fantastic. Pressing the diagnostic performs tests of the chipset, cpu, memory, hard drive and more for 6 hours and then tells me the result. Or I can run Burn in and test it much more extensively.
LOL .. we had quite a discussion a few years back about this .
Here's a post thats quite amusing : https://forum-en.msi.com/index.php?topic=63480.0
I have experienced full so called "prime stable" test over 8 hours just having HotCpuTest fail as it just doesn't do prime numbers calculations or Pi calculations but some more and it's one of the best progs to get you down to earth when you thought your system was overclocked stable.
In addition back then there was some faults in prime95 build x.xx (don't remember) with certain setup with A64 page file size and amount of memory.
Was like talkin' to certain stoneheads back then .

CE Benchmark/Performance Best Practice Tips

We are in the early stages of starting a CE project where we expect a high volume of web service calls per day (e.g. customer master service, material master service, pricing service, order creation service etc).
Are there any best-practice guidelines which could be taken into account to avoid any possible performance problems within the web service u201Cinfrastructureu201D?
Should master data normally residing in the backend ECC server be duplicated outside ECC?
e.g. if individual reads of the master data in the backend system take 2 seconds per call, would it be more efficient to duplicate the master data on the SAP AS Java server, or elsewhere u2013 if the master data is expected to be read thousands of times each day.
Also, what kind of benchmarking tools (SAP std or 3rd party) are available to assess the performance of the different layers of the infrastructure during integration + volume testing phases?
I've tried looking for any such documentation on SDN, OSS, help.sap.com, but to no avail.
Many thanks in advance for any help.

Hi Ali,
For performance and benchmarking have you had a look at Wiley Introscope?
The following presentation has some interesting information [Wiley Introscope supports CE 7.1|http://www.google.co.za/url?sa=t&source=web&ct=res&cd=7&ved=0CCEQFjAG&url=http%3A%2F%2Fwww.thenewreality.be%2Fpresentations%2Fpdf%2FDay2Track6%2F265CTAC.pdf&ei=BUGES-yyBNWJ4QaN7KzXAQ&usg=AFQjCNE9qA310z2KKSMk4d42oyjuXJ_TfA&sig2=VD1iQvCUmWZMB5OB-Z4gEQ]
With regards to best practice guidelines, if you are using PI for service routing try to keep to asynch services as far as possible, asynch with acknowledgments if need be. Make sure your CE Java AS is well tuned according to the SAP best practice.
Will you be using SAP Global Data Types for your service development? If you are then the one performance tip i have regarding the use of GDT's is to keep your GDT structures as small (number of fields) as possible, as large GDT structures have an impact on memory consumption at runtime.
Cheers
Phillip

Interested in Performance Difference Between Different SL Install Methods?

Go here: http://discussions.apple.com/thread.jspa?messageID=10077299&#10077299.

Run a benchmark for your specific case??
Yes. If you are to implement such an operation, try both, using your actual data, and see which performs best. I can't speak to this particular case, but very often to performance questions is
it depends. So the only way to find out when you are interested for a specific case is to test. And keep in mind that next time it could be different.

Interested in your opinion about PPBM7

Bill and I are working on a new site and a new test. It looks like it will not take much longer and is nearly ready for CS6.
We have invested lots of time in designing the new website and adding functionality and there is still as long way to go, but we are making steady progress. Note that the subscription module in not operational yet, the download file is not up-to-date, the script is not included, etc. but we would like to get your opinion on our progress and hear your comments. Everything now is only based on our PPBM5 results.
Please take a careful and critical look at PPBM6, take a look around the site and consider the navigation, layout, logic, design and - most importantly - how easy it is to find the info you are interested in and the way it is presented. Please be critical, so we can take your considerations and suggestions into account.
After you have looked over this site, you would help us enormously by filling out this survey: Click here to take survey. Note we have only a basic subscription which allows for 100 responses only, so you may be out of luck if you wait too long.

STRONG OPINION - Put Benchmark Results/Detailed Results (full table) by itself and label it "Benchmark Results Table" and move all other items in Benchmark Results section to "Benchmark Results Statistics"
Done.
Benchmark Results/Detailed Results table features don't work at all in Internet Explorer (I have IE v9); works fine in Firefox, but many Win7 users will be using IE
Try with the new template, it may work now. Still some cosmetics to adjust though.
Would like to see new columns in Benchmark Results / Detailed results table: CPU die size (nm), # cpus (like in PPBM5), chipset (i.e. X79, C602, etc.), User Comments (i.e. so DeeDigital could explain why identical hardware went from score of 186 to 149), Disk Comments (i.e. many forum posts focus on where put scratch, projects, media, render outputs, etc.)
That may be feasible when I get the parsing of Speccy.xml completed.
STRONG OPINION - Menu design should be streamlined; This is not that large a site and When "Latest News" "Planning and Building" is up, I see 4 separate menus (at page top, Main Menu on Left, Latest News...All Pages on right, and Planning & Building a NLE System at lower left.
Done.
Suggestions to streamline:
1) Only show "All Pages" for all areas; if you find you must have this level of sub-section, do it with a drag-down box at top and bottom of the section like many review sites do
2) Have all menus at top; this is nicer too when someone wants to print something out
Done.
Need to clearly state what versions of CS the new benchmark is compatible with
Will be done.
Suggest adding a lifetime Platinum subscription option for say $100 or $150; that's the one I would select BTW if it were available
Also suggest dumping the Bronze and Gold options; there too many options for new subscribers
I'm looking into that.
Update copyright to 2013 (i.e. bottom Methodology page)
"Buy a subscription" should be "Select a Subscription" since entry level is free
Remove the "We are volunteers!" banner to be consistent with new paid subscription fees; or, if the fees are purely going to internet fees, etc., explain that somewhere
Done, but working on the template now for the footer.
Font size selector is broken on Buy a Subscription page
Suggest using www.ppbm6.com instead of www.ppbm7.com to reduce confusion (it seems that you also own this domain site)
Will look into that.

How to run SAP Benchmark

Hello,
I am looking for an Benchmark which I can run in a SAP System. I read about the SAP SD Benchmark. With this benchmark I would like to simulate a load on the system. Next I would adjust some system parameters concering buffering of tables and table buffering types as well and then running the benchmark anew...
But how can the benchmark be run in my system?
Is there any tutorial available?
I do not know much about this...
Thanks very much

Hello Holger,
The SAP Standard Application Benchmarks and Benchmark Tools are offered for SAP's Global Technology Partners and SAP internal usage only. The tools require expert knowledge. If you are interested in running a certain benchmark you should get in contact with your hardware vendor or the SAP Test Management Consulting.
Volume tests require good project planning and a large amount of resources for infrastructure and people.To predict the system behavior it is often sufficient to test the scalability of the system with a series of single user performance tests and varying workloads.
Best regards,
Birgit

Hard drive benchmarking.

Hi,
I have two hard drives, one of which I'd like to use for Arch (/, /boot, /home, ...), so I'm trying to figure out which one would be best suited for the task.
I have the following questions :
-Are these commands an accurate way of ranking them:
dd if=/dev/zero of=tempfile bs=1M count=1024 conv=fdatasync,notrunc
echo 3 > /proc/sys/vm/drop_caches
dd if=tempfile of=/dev/null bs=1M count=1024
-Does the fact that one of the disks is mounted as / significantly alter the results ?
-Is the LVM overhead measurable ?
-The rudimentary results I obtained show that one disk is better than reading while the other at writing (R-W : 70MB/s - 57MB/s, R-W : 108MB/s - 38MB/s) ; my intuition tells me that for a root partition, the reading speed matters more than writing, is this correct ? At what "ratio" or absolute value does this stop being the case ? Other factors (e.g. for a system with high swap usage, writing speed should matter more) ?
Feel free to offer links or additional information.
Thank you for reading, and potentially helping (me, and other readers from the future).

In short, no. Not by a long shot. In order to do precise measurement you'd have to go beyond volume management, let alone the filesystem.
-Does the fact that one of the disks is mounted as / significantly alter the results ?
Most likely yes. Depends on how the box is used during the test.
-Is the LVM overhead measurable ?
No. The testing should be done under LVM, e.g. on the block layer, or even lower (ATA) as long as you're interested in hardware-related numbers and not benchmarking filesystems. But even low-level test results are questionable, see below.
-The rudimentary results I obtained show that one disk is better than reading while the other at writing (R-W : 70MB/s - 57MB/s, R-W : 108MB/s - 38MB/s) ; my intuition tells me that for a root partition, the reading speed matters more than writing, is this correct ?

These results can be biased heavily depending on testing conditions. If you want to measure hard drive's performance, go for more low-level tools. And even when you finish the tests, the results won't tell you which drive will behave better under regular working conditions. Many performance factors are dependent on software, being it the controller firmware, the hard drive firmware or the operating system. Unless the two drives have big differences on the hardware level (like, say, higher RPM, larger cache, etc.), it doesn't make much sense benchmarking them against each other.
Go for reliability, not performance. Run some SMART tests, badblocks, etc. and then choose the worse drive for OS and the better one for data.

How do you get songs back that have been lost in a computer crash?

About 2 months ago my windows had crashed. We fixed it and everything but noticed that all of the songs from my account disappeared. The file name was there but the actual song would not play. If i am to click on one it would say this.
The song " anything" could not be used because the original file
file could not be found. Would you like to locate it"
It would have an option where you could click yes or no. The first time it happened, I clicked on the yes and it would have me browse through all my files, of course none of the songs found. I have all the songs that I really wanted on my ipod nano still. Is there a way to load these songs back on the computer? Some of the songs are from cds as well as purchased from itunes.

If you have any iTunes Music Store purchases the transfer of purchased content from the iPod to authorised computers was introduced with iTunes 7. You'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
The transfer of content from sources such as songs imported from CD is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. Have a look at the web pages and documentation, this is just a small selection of what's available, they are generally quite straightforward. You can read reviews and comparisons of some of them here:
Wired News - Rescue Your Stranded Tunes

TuneJack Windows Only (iPhone and iPod Touch compatible)

iDump Windows Only
SharePod Windows Only
iPodRip Mac & Windows

Floola Mac & Windows
iGadget Mac & Windows (iPhone and iPod Touch compatible)
iRepo Mac & Windows (iPhone and iPod Touch compatible)
iPod Access Mac & Windows (iPhone and iPod Touch compatible)
TouchCopy Mac & Windows (iPhone and iPod Touch compatible)
There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these

PLEASE HELP!! How Do You Restore ITunes Library From IPOD Back To Computer

My entire library on intunes has been deleted and now all I have left is the music which i still stored on my ipod. I have done a total search on my PC and there is no track listings at all. My only chance is to restore the itunes library from the Ipod back to the PC. Is this possible and how do you do it. Am totally gutted and cant beleive the files are gone. Plllllease help me.

If you're using iTunes 7, you can copy purchased music back to iTunes directly. If you're not using iTunes 7 or want to copy other tracks, the easiest way will be to search VersionTracker for "iPod". You'll find a number of utilities that can transfer your tracks and your playlists from your iPod back to your PC.
It's also possible to do this manually, but the procedure is rather involved. If you're interested, though, see this thread:
MacMuse: Computer crashed
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Discussions page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic, both in the relevant forums, in the User Tips Library and in the Apple Knowledge Base before you post a question.

Can you no longer have a background color for the text box in the new version of hp photo creations

just updated to the new version of HP Photo Creations, used to be able to have a colored background for the text box - is that no longer possible in this new (not better) version????!!!!! Uuuuuuuuuugh

Hi Lainey.
Thanks for asking. We're working on bringing back that feature. In the meantime, here's another way to add text backgrounds: Add a placeable graphic and then click the Arrange button to send it to the back, behind the text.
That approach also gives you more interesting shapes. The new alignment guides make it a snap to align a graphic with a text box. In the example below (it may take a day for the image to show up here), I also used the new Premium Editing Features to change the color of the graphic.
P.S. — Applying a thick border to an empty text box (also using the Premium Editing Features) is another way to create a background shape. That has the advantage of letting you pick any color for the box. You'll also find several new text styles at the bottom of the new text menu.

Calculation of Interest on overdue witholding taxes

In my scenario the interest needs to be calculated on the overdue payments that have not yet been paid by the client to the goverment of TDS so deducted by the system. The interest needs to be calculated from the 7th of next month till date the amount is actually paid. The tds so deducted in the period 1-7th of the month will not be liable for interest calculation. Again in the next month the same cycle needs to be repeated for interest calculation.
Can anyone help me out if how to achieve the same.

Anurag Gupta

Hi
You may like to check the config from the below angles :
1) interest payment is produced if the credit interest (because of interest calculated on items paid before the due date) is greater than the debit interest.
2) Calculate interest on items paid before due date
Indicator which means that credit interest is calculated for items paid prior to their due date, provided that the item paid was not subject to a cash discount. Interest is calculated using credit interest rates.
Note
The system calculates credit interest only on those clearing transactions where all payments were made before the due date. If you do not select this option for those transactions then the items are ignored.
This option has no effect in the case of clearing transactions where payments are made both before and after the due date. For transactions such as these, interest is always calculated on the basis of debit interest.
For partial payments and down payment offsetting items that are made before the due date of the invoice, interest is calculated from the document date if this indicator is set. If it is not set, interest is calculated from the due date of the invoice.
3) Calculate Interest as of Due Date for Net Payment
Indicator which means that interest is calculated as of the due date for net payment; otherwise, you pay interest as of the settlement period lower limit (if the due date for net payment is before it) or as of the date of the last (according to the master record) interest caluclation (if the corresponding parameter is set).

Calculation of Interest on Security Deposits Maintained with Vendors

Hi Friends,
We have some problem on Line Item Interest calculation.
We want to calculate Interest on Security Deposits(Spl GL) given to Vendors.
There is no Interest on Normal Items.
When we run Interest (f.47) it not calculating on cleared items eventhough we select interest for all items.
Example:
We paid Deposit on 01.01.2007 an amount of $10000
We recieved back total amount of Deposit($10000) on 15.02.2007
and when we run interest run (f.47) its not calculating any interest.
But we want to calculate interest for the period the deposit outstanding i.e. from 01.01.2007 to 14.02.2007.
Can any one help us in this regards,
Thanks in Advance,
