Db_deadlock utility questions and other

Hello,
First of all i want to say tha i m so new to databases that i may ask silly questions.
I have an application (metadata server) that i want to replicate.
I have made all the steps to build my replica. When i try to execute a mkdir command
i m getting a deadlock or my application make db wait for ever. If i put the no locking flag,
my db works fine but does not replicate with the other metadata server. So locking i reguired.
Now i got 2 questions i tried to run db_deadlock utility.
1. The results were 8 lockers found and 0 rejected.
This means that there is no deadlock? and it is my application "fault"?
2. The application is not designed for Bdb. it is on unix and it uses Posix threads.
this reference distribes my problem? http://pybsddb.sourceforge.net/ref/txn/other.html
(this is the dump questions i think).
Thanks

FW800 isn't as fast, potentially, as SATA is but if you cannot put drives on the internal bus then FW800 is a far better choice than FW400. There aren't many drives that will transfer faster than the FWW800 bus. Setting up two striped RAIDs and using one as the mirror of the other will provide protection against drive failure but not necessarily redundancy. Whatever is written to one RAID is automatically written to the other, hence if data are corrupted on one, it will be corrupted on the other. However, if you are using this setup as a backup system, then it provides redundancy.
Now whether you need a RAID to accomplish this is another question. Bare drives are now available as large as 1 TB, so unless you need 2 TBs of data storage you could satisfy your plan without a RAID.
You can use Disk Utility to create a software RAID or you can purchase third-party software. Either will work. OS X can create RAID0, RAID1, RAID5 and RAID0+1.
I can't tell you how to box up the system. I don't see any difference between one case with 4 drives or two cases with two drives each.

JVC Camcorder Question and Others....

Hi,
I have a few questions... I have a JVC GZ-HD30U camcorder and everything works ok but I have a rather annoying issue and was wondering if there is a resolution. I can import around 15min at a time of video but every time I select too many clips my import errors out... Basically some of the video clips import fine and the rest say "error" in red and i get a message that there were XX amount of clips that imported fine and XX did not import?
Does anyone else have this issue with JVC? Any other camcorder?
I really take a lot of HD footage and need a reliable camcorder that I can use.. Can someone either help with the issue listed or suggest (without sending me the link of compatible camcorders on the apple site) a great camcorder? I am looking for someone that has had first hand experience of a camcorder they would suggest if there is no solution.
Lastly, I was also wondering if I could get a SD camcorder and use the built in SD card slot on my iMac to import instead of USB??? Has someone tried this?
Thank you!

This is the way that I import all my camera footage to my macbook i.e. via the SD card slot.
Rather than look for the correct cable I just pop the card out of the camera and into my macbook.
Then I usually copy all the files into a folder on my desktop or an external HD then import what I want into iMovie when I am ready (iMovie: File > Import > Movies...).

I will address your second question.
First, make sure your iPhone and iPad have absolutely identical Apple IDs. If they do, use that Apple ID in Settings > iCloud on your iPhone to select the "Notes" option. Lo and behold, all your iCloud notes should appear on your iPhone.

MacBook Pro 13" Hard Drive and other questions

Hi there,
I've just purchased a 13" MBP which I absolutely love but have a few questions about upgrading it. I want to swap out the hard drive for a larger capacity but just want to make sure I purchase one that will fit.
I'll number the questions for ease of answering.
1. Will this hard drive be correct? I know it's a 2.5" SATA but I didn't know if the dimensions are ok for the 13" MBP.
http://www.amazon.co.uk/WD-Scorpio-Black-WD3200BJKT-internal/dp/B001FBJJQ4
2. Will the difference between a 7200rpm 16MB cache drive and a 5400rpm 8mb cache drive be noticeable? I can get a 500gb slower speed drive for the same price and while the capacity increase would be useful, I would prefer a faster drive if it's noticeable.
Many thanks

That article I believe to be incorrect! The author never mentions which Scorpio drive....Blue or Black. The Blue does not contain a free fall sensor option as the Black is available with our without free fall sensor. The free fall sensor will interfere with the Sudden Motion Sensor (SMS) built into the Mac. SMS can be disabled but my experience first hand with the Scorpio Black in my MBP 13 was not good even after disabling the SMS and merely using the free fall sensor in the Black. If you want a 7200 RPM drive and you like West Dig get the Black without the free fall sensor. You will be much happier. I run the Black in several Windows Laptops and it streams fast then the 7200.4 which I also have in a windows laptop and the scorpio black performed better and more stable! I just dont think I personal would not use it on the MBP 13...I took mine out for it was problematic!! If you want a 500 GB go with the Fujitsu or the Hitachi...even the the Western Dig Scorpio Blue with does not have a free fall sensor. The author of that article mentioned ShockGuard that is not a Free Fall sensor and only engages durring spin up or down as well as parks when it is off. This does not sense a fall like the SMS or a built in free fall sensor. Many MBP unibody owner have used the Blue and it has been hugely successful!!! My experience which is very extensive with Seagate as of late has not been favorable. I do not like the latest generation of drives they are producing we are seeing extensive failures (higher % compared to other OEMs). Stick with those three.
If you want battery life, the Fujitsu or Hitachi are very good choices Fujitsu being a little better
For speed the WD Blue is best on synthetic tests but it is a little power hungry. I am sticking with the Fujitsu in real world test it seemed to do better than the others...H2Benchw it wasnt as good. PCmark it did very well. The Gaming, Video and other test it seemed to do well on but not as good in the h2Benchw.

EXSP24 in LE7 and other questions

I have worked out that the sampler instrument editor in LE7 has been removed which is kinda an odd upgrade from Logic Audio 6 imo. If i have this wrong please let me know.
So how do I go about adding in new instruments from sample cd's etc??
I am used to running Logic Audio 6 on my old Imac in System 9 so the new or apparent lack of Logic Folders etc is quite bizarre for me. So if anyone can also throw me some pointers on:
1: Using Reason adapted for Recycle as a rewired instrument in LE7 (I have a feeling this is not possible)
2: Using Absynth within LE7
3: Will something like Kontakt run in LE7?
4: Rewiring Logic into Live or vice versa.
So many questions
Thanks
Paul

You can't edit EXSP24 instruments but you can import several formats:
Akai, Soudfonts, Giga, SampleCell and DLS.
To create your own patches you need some external apps like this:
http://www.redmatica.com/Site/Pages/KM.php
About other questions and supposing that you don't have a Intel Mac:
1. Yes, you can.
2. Logic uses plugins in Audio Unit format; if you have an older version of Absynth you should upgrade to a newer one.
3. Same as above,
4. Logic can act as Rewire host only so you can rewire Live to Logic but not Logic to Live.
cheers

[SOLVED]How to patch the kernel? And other questions

Like the same user who started this thread I'm suffering from hibernation resuming troubles using kernel 2.6.38. In that thread was posted a soluttion that involves patching the kernel.
The patch to apply is this:
http://git.kernel.org/?p=linux/kernel/g … e3e9fc8684
Waiting for the bug to be corrected and a new version supplied is not an option, because this laptop is my main computer and I heavly rely on hibernation.
Here's my trouble now. I don't know if it is possible to patch without recompiling the whole kernel, or it has to be compiled with that patch applied. I have seen the archlinux's wiki guide about compiling the kernel, but found nothing about applying patches (maybe I didn't searched with enought depth).
In case there is needed a full compilation, should I use the vanilla kernel, the Arch Linux one or any of the AUR ones (I said AUR because they're the first that came to my mind)? Should i expect a performance gain with this (apart from fixing the hibernation bug)?
Maybe i'm just doing a bunch of dumb questions, and the only thing I need is to search deeply on the wiki. In that case, please tell me. If not, I rather get some answers around kernel patching and / or compiling questions.
Edit: In addittion, it is possible that all this questions are just newbie ones, I don't know, but as I am willing to learn from this I will appreciate any info or documentation about it.
Thank you.

From the source tree (/usr/src/linux-whatever) execute
patch -p1 < /path/to/fix.patch
then recompile kernel from the source tree.
Basically that consists of executing the following commands from the source tree:
make menuconfig
make
make modules_install
cp -v System.map /boot/System.map-CUSTOM
cp -v arch/x86/boot/bzImage /boot/vmlinuz-CUSTOM
mkinitcpio -k 2.6.38-CUSTOM -g /boot/kernel-CUSTOM.img
and you need to add menu entry in /boot/grub/menu.lst
-k 2.6.38-CUSTOM should corespond to /lib/modules/2.6.38-CUSTOM (replace 2.6.38-CUSTOM with the name of your module directory, name depends on the kernel version and suffix that you gave in menuconfig). Regarding kernel configuration in menuconfig - I can't help you, you could use arch stock kernel config (zcat /proc/config.gz > /usr/src/linux-whatever/.config)
I do these kind of things this way - maybe someone else have a more elegant solution.

My complaints and Questions MP4 M4V video files and other complaints

My complaints and Questions MP4 M4V video files and other complaints
I have been scratching my head as to how to fix my problem and I found some answers and some questions along the way. First of all, I have a video that should be correctly formatted for my iPod. Its specs are:
Kind: MPEG-4 video file
Size: 19.4 MB
Bit Rate: 125 kbps

F:\File\AnotherFile\A3rdFile\TheMovieFileInQuestion.mp4
Wow that was a chore. Apple! Let us drag copy and paste our info tabs information so we don’t have to type all this stuff when we are having trouble. **another problem and suggestion** right there.
Ok, back to the problem of the forum.
From what I can see from http://www.apple.com/ipodclassic/specs.html this file falls in line of everything required in order to be able to play on my iPod. It plays in iTunes fine but will NOT sync with my iPod. I get an annoying message that states, “Some of the Songs and videos in your iTunes library, including “BlaBlaBlaiPondFixYourJunkBlaBlaBla”, were not copied to the iPod “My iPod” because they cannot be played on this iPod.” Why oh why can iTunes play this video file but my iPod cant. Especially when the specs on Apple’s website say it can.
So that was bugging me for a LONG time until I found my “Create iPod or iPhone version” option in the “Advanced” heading. Thank goodness this made my files playable on my iPod. Extremely LONG wait though. I know that other programs convert it in ½ the time. But times not to important as long as it gets done, (would be very convenient if it was faster though **Problem and suggestion**)
Ok, now that I have used the “Create iPod or iPhone version” option it has slowly but surly converted my video. Ok, here is my main problem, the new file which is the result of the conversions information is as follows:
Kind: MPEG-4 video file
Size: 35.4 MB
Bit Rate: 125 kbps
Date Modified: 8/18/2009 2:15 PM
Play Count: 1
Last played: 8/21/2009 1:28 PM

C:\File\WhyIsThisNewFileInMyMusicFolder\TheMovieFileInQuestion.m4v
So basically it has made my file bigger *not a bonus in my book* greatly increased my Bit Rate *another interesting feature*, and I think the biggest change it has changed it from an .mp4 to an m4v.
Why does it need to be an .m4v I could have sworn some of my videos were or are in mp4 which shouldn’t matter anyway because I was under the impression that iPods could play mp4 files. So that’s my biggest complaint and question. Why can my 80GB classic iPod not play my MP4 files and why am I forced to convert them??
This conversion also creates 2 files in iTunes when I am done which is annoying because I have to go into my files info and look to see what file is the mp3 in order to remove it. Very annoying I can open my iPod options and see the files and some are faded (the ones it can not play) why can’t I remove them from that area.Suggestion Apple please make files that cannot be played on my iPod stand out some how for easier cleaning Suggestion. Thank you.
Speaking of cleaning iPods, when I moved my entire library to an external drive I was faced with a terrible problem. “This file could not be found, would you like to locate file”, I was faced with this annoying message at least 600 times. Now I am glad that iTunes has a little “!” mark to show dead links so that you do some minor cleaning, Good Job iTunes No compliant there. However iTunes has no way of selecting all the broken files for major cleaning (like in my case). Going through and deleting over 600 files 1 by 1 is extremely time consuming and annoying. **Suggestion Apple please add more cleaning features for organizing iTunes**.
Ok, speaking of organization now, another problem that appeared when converting my video files was that it put my new videos into the location where I have all my songs (my external hard drive) why can’t it put the new files in the locations of the original file? I have my computer highly organized and my original files were in that drive in that folder for a reason. If I could open my original file and skip the conversion, my iTunes would go to that specific folder to access the file which is fine. But now these new conversion files are elsewhere taking up space and disorganizing my computer. True I can go into the new location and move the files to where I want them (original location) but I don’t think I should have to hunt them down, copy, move, delete ect etc for all these files over and over. Very annoying, time consuming and should be unnecessary. **Suggestion Make file creation and location more customizable, and user friendly, your customers will love you for it**.
Well since I have gotten into Apples iTunes and iPod problems that I have had to face I might as well bring up one or two more problems and suggestions. About a month after purchasing my iPod a sibling bought one as well. His however is way more convenient then mine. I suppose he has a 5th gen. so here is my question: why does he have a search option and I don’t!!!! Why does he get more features every so often and I don’t?! Why can’t Apple write some software for us classic guys which got the iPods going! It’s very annoying when I have to spend more time looking for the song then I spend actually listening to it, when he can pull his up in like 3-6 seconds? I highly doubt the hardware between our iPods is that dissimilar and even if they are why cant software be written for us. **Suggestion treat all your customers good not just the newer ones, and make some more features for the classics like me and my iPod.” We will be grateful for it I promise.
Ok, I am almost done. Let me just recap my questions, I know my post is kind of lengthy.
#1. Why can’t my iPod play MP3 video files? And why do I have to convert to almost all the same settings except changing it from an mp4 to an m4v. according to Apples own site I should be able to play .m4v .mp4 and .mov files!! Note: remember iTunes plays them fine but my iPod will not.
#2. Would be much more convenient to be able to copy the information from the windows in iTunes so that problems and trouble shooting would be much easier. A little check on off options in iTunes advanced settings would be terrific.
#3. Why is the conversion so slow? Please speed it, you have the power. Convenience is the thing that sells products.
#4. Files that cannot be played on the current iPod need to be easier recognized for simpler cleaning.
#5. Also make an easier way to select all dead link files for faster cleaning, deleting, etc. This one is important.
#6. Make a user friendly way to change where my files are going to end up once I convert them for iPod more options and better customizable settings are need.
#7. One of the most important is ADD A SEARCH OPTION. I and we classics will LOVE Apple for it.
For you readers, I apologize for the long post, and any grammatical errors you might find throughout it. These are problems that I have faced with these programs and hardware and I wanted to make sure they got acknowledged and hopefully addressed. Any information about why I cannot play MP4 Video files on my iPod would be the best. If anything in my post gets answered that’s the one I want most. Will save me a lot of hassle.
Thank you all and I look forward to your suggestions and comments. All are welcome and appreciated.
Sincerely,
Bond, James

Was playing with iTunes and thought of another suggestion! Let us play files in iTunes from an iPod! A friend or sibling should be able to plug his iPod into my computer open iTunes and play any of the files there. Many times I have wanted to show a movie clip or video to a friend, and I have the dock so I can do it on my T.V. but play it on their computer in their iTunes forget it. That would be a very nice feature as well so we can watch our movies at maximum size or listen to music on a better sound system, just another suggestion that would be nice. Thanks

Icloud or itunes backup, only backs up app data, not the app itself.

Few basic questions about sharing and other stuff..

Hi there!
First of all I know where are "101" pages, but they are not giving detail information.
1.I know there are some folders where I can put files, web-sites and other in order to enable sharing.
What do I have to do to enable other users (from internet to)
- view my webpage when they enter my IP address in browser
- to access files which I want them to be able to acces (with user and password required)? I know there is sth like sharing, and windows sharing, but I give access to my all user folder, do I have to create new accounts on my mac?
2. It's kind of small problem, but can I run apps in finder using only keyboard (enter causes rename action)
3. Why doesn't safari keep addresses I used in addres field after few days?
The most important question is 1.
Will be gratefull for help.
Thanks
Adam Mscisz

1. Start Personal Web Sharing from the Sharing pane of System Preferences; if you have a router between your computer and the Internet, ports 80 and 443 need to be forwarded to your computer. You can set this up from the router's configuration page, which is accessible by finding the router address in the Network pane of System Preferences and putting it into a web browser. See this article for instructions on how to password protect your shared files.
2. You can use the Command and O keyboard shortcut to open the selected item in the Finder.
3. The default setting in Safari is to keep the history for 7 days. You can use the method posted by ptejad in this article to extend the time Safari remembers the history for. The method at the top of the linked page won't work in Tiger.

I had a windows laptop, and I save files like photos, documents, videos and other things on an external hard drive, and now I want to move those files to the Mac book Pro, and then move those files again to another external hard drive 1T. My question is:

I had a windows laptop, and I save files like photos,documents, videos and other things on an external hard drive, and now I want tomove those files to the Mac book Pro, and then move those files again toanother external hard drive 1T. My question is: Is it possible? Doing this willnot affect the files that I had in windows? No information is lost? or how cani do it?

Connect the external drive to your Mac and drag the files from it to your Mac's internal drive. Then dismount and disconnect the external drive, connect the 1TB external drive, and drag the files from the internal drive onto the external. Nothing will have been deleted from any of the drives up to this point; the files will only have been copied. Verify that the files are readable. There's no reason they shouldn't be; this is just a precaution.
Now if you wish to delete the files from any of the drives, drag them to the Trash, and Empty the Trash while the drive from which they came is still connected. If you disconnect the drive before emptying the Trash, the files you were trying to remove from it won't be deleted. They'll remain in the Trash and continue to take up space on the drive.
Note that if your external drives are in NTFS format, you won't be able to write anything to them or delete anything from them, though you will be able to read and copy the files they contain. The NTFS disk format is read-only to the Mac OS, unless you have a third-party NTFS driver installed. To make your drives cross-platform readable and writable, you must reformat them in the FAT32 or ExFAT format.

Adding a RAID card to help speed up export (and other drive question) in Premiere Pro CC

First of all, I have read Tweakers Page exporting section because that is where my primary concern is. First my questions, then background and my current and proposed configurations:
Question 1: Will adding a hardware RAID controller, such as an LSI MegaRAID remove enough burden from the CPU managing parity on my software RAID 5 that the CPU will jump for joy and export faster?
Question 2: If true to above, then compare thoughts on adding more smaller SSDs for either a one volume RAID 0 or smaller two volume RAID 0 to complement existing HDD RAID 5. That is, I'm thinking of buying four Samsung 850 Pro 128 GB SSDs to put in a four disk volume to handle everything (media/projects, media cache, previews, exports), or split it up into two volumes of two disks each and split the duties, or keep the four disk volume idea and put the previews & exports on my HDD RAID 5 array.
The 850's are rated at SEQ read/write: 550/470 MB/s thus I could get around 2000/1500 MB/s read write in a four disk RAID 0 or 1/2 that if I split into two volumes to minimize volumes from reading/writing at the same time, if that really matters with these SSDs?
The Tweaker's page made a few comments. One is splitting duties among different disks, rather than a large efficient RAID may actually slow things down. Since the SSDs are much faster than a single HDD, I'm thinking that is no longer accurate, thus I'm leaning toward the Four disk configuration putting OS & Programs on C drive, Media & Projects on D (HDD RAID 5), Pagefile & Media Cache on SSD (2-disk RAID 0) and Previews &Exports on 2nd SSD RAID 0 (or combine the two RAID 0's and their duties).
Just trying to get a perspective here, since I haven't purchased anything yet. Any experience/stories, I would appreciate.
My current drive configuration:
My D drive is software RAID 5 consisting of four 1 TB Western Digital RE4 (RED) 7200 RPM HDDs with a CrystalDiskMark SEQ Read/Write of 339/252 MB/s.
The C drive is SSD 500 GB (Samsung 840 (not Pro) and does 531/330 MB/s. My OS, Program Files and Page File are on C, and data/media files/project, etc all are on the RAID drive.
Problem:
Current setup allows for smooth editing, only the exporting seems slow, often taking between two and two and a half times the video length to export. Thus a 10 minute video takes 20-30 minutes to export. 15 minute video can take 30-40 minutes to export. The first 10% of the two-pass export takes under a minute (seems fast), but it gets slower where the final 10 or 20% can hang for many minutes like my system is running out of steam. So where is the waste?
I have enabled hardware acceleration (did the GPU hack since my GPU isn't listed) and it may spike at 25% usage a few times and eat up 600 MB of VRAM (I have 2 GB of VRAM), otherwise it is idle the whole export. The CPU may spike at 50% but it doesn't seem overly busy either.
Our timeline is simple with two video streams and two audio streams (a little music and mostly voice) with simple transitions (jump cuts or cross dissolves). We sometimes fast color correct, so that might use the GPU? Also, since we film in 1080 60P and export 1080 29.97 frames/sec, I think that is scaling and uses the GPU. I know without the GPU, it does take a lot longer. I have ruled out buying a faster GPU since it doesn't appear to be breaking a sweat. I just need to know if my system is bottlenecked at the hard drive level because I'm using software RAID and my disks are slow and will hardware RAID significantly reduce the CPU load so it can export faster.
Our files are not huge in nature. Most our clips are several MBs each. Total project files are between 5 GBs and 10 GBs for each video with Windows Media File export being 500 MB to 1.2 GB on average. We shoot using Panasonic camcorders so the original files are AVCHD, I believe (.MTS files?).
Considerations:
1. I'm thinking of buying (and future proofing) an LSI Logic MegaRAID 9361-8i that is 12Gb/s SAS and SATA (because some current SSDs can exceed the 6Gb/s standard).
2. I'm not replacing my current RAID 5 HDDs because not in my budget to upgrade to 6 or more large SSDs. These drives are more important to me for temporary storage because I remove the files once backed up. I don't mind a few inexpensive smaller SSDs if they can make a significant difference for editing and exporting.
I can only guess my HDD RAID is slow but the CPU is burdened with parity. I would imagine running RAID 10 would not help much.
My setup:
my setup:
CPU - i7-3930K CPU @4.5 GHz
RAM - G.SKILL Ripjaws Z Series 32GB (4 x 8GB) DDR3 2133 @2000
Motherboard - ASUS P9X79 WS LGA 2011
GPU - Gigabyte GeForce GTX 660 OC 2GB (performed the compatibility list hack to enable hardware acceleration).
C drive - 500 GB Samsung 840 SSD (Windows 7 Pro 64 bit and programs).
D drive - four 1 TB WD RE4 Enterprise HDDs 7200 RPMs in software RAID 5
Case - Cooler Master HAF X
CPU Fan - Cooler Master Hyper 212 EVO with 120 mm fan
Power Supply - Corsair Pro Series AX 850 Watt 80 Plus Gold
Optical Drive - Pioneer BDR - 208DBK
thanks in advance,

........software RAID 5 off the motherboard ??????......NOT a good idea, from what I have read here on this forum from experts like Harm Millard and others. They have mentioned a LARGE overhead on the CPU doing this....causing sub-par performance. RAID 0 off the motherboard will NOT do this, however.....RAID 0 would provide optimum speed, but, with the risk of total data loss if ANY drive fails. You may wish to reconfigure your RAID to be RAID 0...BUT...you would need to DILIGENTLY back up its entire volume onto perhaps a quality 4TB drive very frequently.
A lot depends on the nature of your current and FUTURE codecs you plan to edit. You may not want to sink a lot of money into an older setup that may have trouble with more demanding future codecs. For now, in the 1080p realm, your rig should be OK....the read/write performance on your CURRENT RAID 5 setup is not great, and a definite drag on the performance. The rest of your components appear to be fine.....the Samsung SSD, though not ideal, is OK.....it's write speed is WAY lower than the Pro model,but, the drive is used mainly for reading operations. Since you have Windows 7 Pro, and NOT Windows 8.......you CAN put the entire windows page file onto the RAID 0 you might create.....this will take that frequent read/write load OFF the SSD. Read the "tweakers Page" to see how to best TUNE your machine. To use your current setup most efficiently, without investing much money, you would :a. create the RAID 0 off the motherboard, ( putting all media and project files on it ) b. install a quality 7200rpm 4TB HDD to serve as a BACKUP of the RAID array. Then, install a Crucial M550 256GB or larger SSD, ( close in performance to Samsung 850 Pro...much cheaper), to put all previews, cache , and media cache files on....AND to use as " global performance cache" for After Effects...if you use that program. Exporting can be done to ANOTHER Crucial M550 for best speed...or, just to the either the FIRST Crucial or, the 4TB drive. Your current GPU will accelerate exports on any video containing scaling and any GPU accelerated effects. Your CPU is STILL important in SERVING the data to and from the GPU AND for decoding and encoding non-GPU handled video....your high CPU clock speed helps performance there ! You may want to check out possibly overclocking your video card, using MSI Afterburner.or, similar free program. Increasing the "memory clock speed" can RAISE performance and cut export times on GPU effects loaded timelines,or, scaling operations. On my laptop, I export 25% faster doing this. With my NEW i7 4700 HQ laptop, I export in the range of your CURRENT machine....about 2 to 3 times the length of the original video. PROPERLY SET UP...your desktop machine should BLOW THIS AWAY !!
Visit the PPBM7 website and test your current setup to possibly identify current bottlenecks,or, performance issues. THEN, RE-TEST it again, after making improvements to your machine to see how it does. Be aware that new codecs are coming (H.265 and HEVC,etc.) which may demand more computer horsepower to edit, as they are even MORE compressed and engineered for "streaming" high quality at a lower bandwidth on the internet. The new Haswell E...with its quad-channel memory, 8 core option, large number of PCI gen. 3 lanes, goes farther in being prepared for 4K and more. Testing by Eric Bowen has shown the newer PPro versions provide MUCH better processing of 4K than older versions.
