Speed Comparison between Quadro FX 5800, 4800, 3800
Question: Speed Comparison between Quadro FX 5800, 4800, 3800
Both Adobe and Nvidia technical support said they do not have speed comparison benchmarks on the same Windows 7, 64 bit computer for both rendering and encoding between the Quadro FX 5800, 4800, and 3800. Does anyone know of such speed comparisons. Thanks in advance.
I just had a new computer built using a 6 core AMD processor and 16 gb Ram, cs5, etc. Is it possible for me to apply your benchmark and how would I do it?
Thanks,
John Rich

Is there a speed comparison between xpath query
Is there a paper whit speed comparison between xpath query on XML, stored with all oracle's techniques?
Thank you and sorry for my englishNot currently. Since there are no industry standards for XML benchmarks that are accepted by all major vendors Oracle policy prevents us from publishing numbers. However if you have examples of what you are looking for I can give guidance.

Speed comparison iPhone 3GS and 4?
Hi,
I am developing a game using Air 2.7 but I only have an iPad 1 to test it on. The speed is really good (a steady 60fps) but I'm a bit curious how fast it will run on 3GS.
Have you guys done any speed comparisons between iPhone 3GS and iPhone 4?
I guess the speed on iPhone 4 is about the same as iPad 1?
Thanks,
/AndreasI have tested the same vector animations on iPhone 4, iPad 2, and iPhone 3GS. If you have selected to use high resolution, the performance on the 3GS and iPhone4 will be similar, because the iPhone 4 will have to update four times the screen area of the 3GS. The iPad 2 may be slightly faster, and I guess you may be right about the iPad 1 being similar to the iPhone 4. If you use standard resolution, the iPhone 4 may be the fastest of them all.

AppleScript speed difference between 10.4 & 10.5
This post is related to a question I posed in March 2009 (https://discussions.apple.com/message/9226100) regarding the speed difference between AppleScript text handling in OS X 10.5 compared with 10.4.11.
I have recently written a script to search through a text file which is an xml file exported from WorkGroup Manager. The file, which is approximately 1.8 MB, contains all the user names on the school server (just over 1720 of them), their settings and any other information we have added. After adapting some script ideas (using text delimiters and offsets) which I found on the internet to assist with counting the number of users and searching through the information of each one, one at a time, I have a script which works far in excess of my expectations in terms of speed when run under OS X 10.4, but runs slower than molasses in winter under 10.5.
The script counts the number of accounts, extracts each user's log-in name and also their actual name (which we have entered under a 'general info' or 'comments' field - I can't remember exactly where, but it is stored in the file), makes up a complete list of all account names (with the actual name, if present) and also makes up a subset of this information into a separate list which contains only the log-in names of those whose actual name has not yet been recorded on the server, then saves both lists to separate text files.
My original attempts, using some rather clumsy text searching and comparison techniques, took about 1-2 minutes to go through the whole procedure. After some internet searching, head-scratching and a bit more more work, the finished script, when run on my G5 under OS X 10.4.11, takes less than 3 seconds to do all I have described above, including the writing to text files. To say I was pleased would be an understatement!
Because the school/work environment, where the script would be run, is all OS X 10.5 or higher, I thought I should test it out under at least OS X 10.5. The script was developed on my DP 2.5GHz G5 with 8GB RAM running OS X 10.4.11. Using a fresh, clean installation of 10.5 I ran the script and was extremely disappointed. After letting it run for more than 20 minutes and still not finishing, I force quit AppleScript and reduced the number of accounts in the file. 40 accounts took 3 seconds, 60 accounts took 6 seconds, 80 took 11 seconds, 100 took 19 seconds and 120 took 27 seconds. I eventually let the script run right through - total time taken to process 1720 users was 65 minutes, compared to 3 seconds under 10.4.11!
Given that it was tested on the same Mac, with the same amount of RAM, using the same script and the same original text file, the only variable left (that I can think of) is the change of OS version - 10.4.11 vs 10.5.
As was pointed out to me in my previous post, AppleScript in OS X 10.5 handles all text as Unicode and has a greater overhead in processing time as a result. I have implemented the various bits of advice offered by respondents to my original post and changed the way I handled lists, etc. Obviously, if the script works so speedily under 10.4.11, I must have done something right in terms of code optimization/efficiency. It's when that exact same script is run under OS X 10.5 that it slows down incredibly. I even tried it on a 2.66GHz Intel Core 2 Duo iMac running 10.5.8 - it still took 40 minutes and Activity Monitor showed CPU usage by Script Editor constantly above 80% (often well above 90%). Saving the script as an application made no difference in the time taken.
Does anybody have any knowledge about what makes AppleScript Unicode-only text handling so slow? In this case, it is 1300 times slower! Is there any way of coercing/restricting the text handling/parsing to ASCII? If I really have to, I will set up a humble eMac at school with 10.4 on it just to handle large text files quickly with AppleScript, but I would prefer to be able to do it on the normal work Macs which have 10.5 or later on them. As mentioned, under 10.4.11 the script processes the 1.8MB text file with 1720 users and writes results to two files - all within 3 seconds, so I'm not really looking for coding suggestions unless they are directly related to what has changed in AppleScript under OS X 10.5. Without sounding too smug, the script works properly and speedily (at least in 10.4). I really would like to learn about the changes in AppleScript in OS X 10.5 and how to cope with or work around those changes.Hi,

Anyone done a comparison between compressor & Squeeze 5 for h.264 output?
Anyone done a comparison between compressor & Squeeze 5 for h.264 output?
I'm not that concerned about speed, primarily interested in quality.
Intended delivery would be over the web, but also on an HDTV flat screen in a waiting room at best resolution (would H.264 be the best choice for that use?).
Source would be 1920 x 1080 24p ProRes 422 (recorded directly from HDMI using a humble Canon HV20 and an Intensity card).
As to the size, that's becoming less of an issue with bandwidth such as it is. 20-30% larger wouldn't make a difference to me. -

Go to Solution.like i said above, the D10 should support the 5800 because the 4800 works in mine and they're based off the same generation of architecture and BIOSes. the S10 is an unknown but i'd be surprised if it didn't work.

Performance end to end testing and comparison between MPLS VPN and VPLS VPN
Hi,
I am student of MSc Network Security and as for my project which is " Comparison between MPLS L3 VPN and VPLS VPN, performance monitoring by end to end testing " I have heard a lot of buzz about VPLS as becoming NGN, I wanted to exppore that and produce a comparison report of which technology is better. To accomplish this I am using GNS3, with respect to the MPLS L3 VPN lab setup that is not a problem but I am stuck at the VPLS part how to setup that ? I have searched but unable to find any cost effective mean, even it is not possible in the university lab as we dont have 7600 series
I would appreciate any support, guidence, advice.
Thanks
ShahbazHi Shahbaz,
I am not completely sure I understand your request.
MPLS VPN and VPLS are 2 technologies meant to address to different needs, L3 VPN as opposed as L2 VPN. Not completely sure how you would compare them in terms of performance. Would you compare the performance of a F1 racing car with a Rally racing car?
From the ISP point of view there is little difference (if we don't want to consider the specific inherent peculiarities of each technology) , as in the very basic scenarios we can boil down to the following basic operations for both:
Ingress PE impose 2 labels (at least)
Core Ps swap top most MPLS label
Egress PE removes last label exposing underlying packet or frame.
So whether the LSRs deal with underlying L2 frames or L3 IP packets there is no real difference in terms of performance (actually the P routers don't even notice any difference).
About simulators, I am not aware of anyone able to simulate a L2 VPN (AtoM or VPLS).

Comparison between cFP and cDAQ
Hi,
I'm looking for (as much details as possible) a comparisons between compact Fieldpoint and compact DAQ hardware. I'm trying to decide which hardware platforms to use.
TIACompact Fieldpoint is for installed, industrial type applications. It has a realtime operating system. The controller runs code to read inputs and operate outputs. The application can be distributed on an ethernet network. There are different modules available for different types of inputs and ouputs.
Compact DAQ also has numerous input and output modules. It is more intended for portable applications. It connects to your PC through a USB port. So the code would need to run on the PC -

Thanks,Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak2, Vista, or Windows 7. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive. -

[AS-CS5] Comparison between text style range and character style
Hi,
It's been a while since I'm not coming on this forum ...
I'm looking to make a comparison between a "text style range" and a character style.
I have no problems, except for the comparison of "fonts".
myCurrentText = text for char…
theStyle = character style id…
I try:
if (applied font of myCurrentText ≠ applied font of theStyle) then set theCharDifference to 1
The selected text give me:
font "Minion Pro Italic" of application "Adobe InDesign CS5.5"
and the character style:
"Minion Pro"
I try "set theTextFont to font of applied font of myCurrentText" -> Error
This is my script (it's too long to post here) <http://db.tt/BLoGPiN>.
Loot at the "on CheckCharacterDifference(myCurrentText, theStyle)"
TIA.
Oli.I've written this, but I do not know if it covers all cases ...
Someone?
Thanks.
Oli.
set theText to item 1 of selection
set theStyleChar to properties of character style 2
-- analysis of the properties of the text
set myTextFontApplied to applied font of theText
set myTextFontFamily to font family of applied font of theText
set myTextFontStyle to font style of theText
-- analysis of the character style
set myStyleCharFontStyle to applied font of theStyleChar
if myStyleCharFontStyle = "" then
set myStyleCharFontStyle to font style of theStyleChar
if myStyleCharFontStyle ≠ myTextFontStyle then set theDifference to true
else
if myStyleCharFontStyle ≠ myTextFontFamily then set theDifference to true
end if

EhP5 Report: Actual/Actual Comparison Between Different Ledgers
Dear all,
Hoping that someone here has faced the same challenge and found a solution...
My client wants to see a side-by-side comparison of the financial statements for several ledgers; ideally three, but two will do.
It appears that EhP5 includes an enhancement of the standard actual/actual comparison report which allows a comparison between two ledgers. However, we are running EhP4, and an upgrade is unlikely to happen very soon. Do you know whether the report is available separately? Our search for a separate SAP note was unsuccessful.
Our other alternative would be to develop a report ourselves, but if a standard solution is available, that would feel rather daft...
Thanks in advance!Thanks for the advice - as the system would not let me create versions for these non-FISL ledgers, I assumed it was not possible to run the report for them at all.
Unfortunately, I do not have the actual/actual comparison for two different years built in, nor the financial statement version, so we may still have to develop a new report (as per project standards, in BI rather than ERP)...
Kind regards -
