Strange CPU Performance issue Mac Pro, Logic 7.2.3......

Hi there,
I am experiencing a strange issue with Logic 7.2.3 and my Mac Pro.
I am running about 70 tracks in a tune I'm writing, with a lot of the EQ and dynamics processed on a Liquid Mix, but am experiencing a lot of CPU spikes, and drop outs in logic.
The System Performance meters are showing that one of the CPU cores is at full capacity, whilst the Activity Monitor is showing a total usage of about 40%.

I have tried every combination of settings in the audio preferences, but cannot seems to get this track to play properly.
With 71 tracks, this machine is currently LESS powerful than the G5 that I have been working on until purchasing the Mac Pro.
I there anything else I can try? Are there any other means of controlling buffer size?
I have a suspicion that this may have something to do with the Plugin Delay Compensation set to 'All' - But without doing this, I cannot use the DSP effects of the liquid mix to work on a Bus! Very frustrating.
Many thanks for the help, any ideas at would be deeply appreciated,

Great!
Thanks for the tips guys.
I have tried to find an offending loop or part in the sequence, but cannot find anything at all thats causing the issue.
My suspiscion is that using the focusrite Liquid mix on a part, that is in turn going into a delay compensated bus, which has another Liquid mix plugin on it, is causing the issues. I use the total mix software in the fireface to perform the summing of the busses, which I think in turn may be causing the PDC to glitch a bit more.
Which is a bit annoying, as the mix in this tune is my best yet!
So I will attempt to remove the liquid mixes that are running in series in a chain, and see if thats the problem, but if that fails, time to re-format again!
I'll let you know how I get on in the next couple of days!
Thanks again,
Adam

JCaps 5.1.3 Sun Solaris CPU performance issue

Folks,
We are experiencing a serious CPU performance issue on our Solaris server with HL7 projects deployed.
The projects consist of the sample HL7 inbound and outbound projects with an additional service sending to a batch local file external for writing journals.
The performance issue occurs when there is volume of data in the queues/topics. As we continue to deploy additional HL7 projects (usually about 6 interfaces), the CPU increases until it reached 100%.

Hi,
I noticed this behavior with the Alert + SNMP Agents installed but not configured. In this situation, the SNMP agent generates traps for all events, leading to high CPU using, even when nothing was processed. Are you in a similar case?

How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.

How is the performance of Mac Pro if i use it as host for windows and linux virtual machines.
I am planning to buy a high performance PC to run my Windows and Linux servers as vitrual machines for my testing purposes.
Initially i planned to build my own computer with recommended configurations but considering space constaints and cooling factors i think Mac Pro can be a choice. But need some inputs if Mac pro (Intel Xeon E5, 12 GB RAM) is good for running virtual Machines.

You could even run Windows natively and still run your VM servers.
I have seen reports and such on MacRumors and elsewhere - run Windows natively as well as VMs (can also do testing and run Mavericks in a VM under Mavericks)
The fast internal PCIe-SSD, plus 6 or 8 cores, and 32-64GB RAM. Of course for $5,000 for 8-core, some Thunderbolt storage and 32GB/64GB RAM you can buy some serious hardware.

Performance Issue Premiere Pro CC 2014 with Late 2013 Mac Pro

Hi all!
Im working Premiere Pro CC 2014 on a Late 2013 Mac Pro 6 core D700s and 32GB RAM on OSX 10.9.4
After the 2014 update i have experience some drop frames and hangs with a new 1080p timeline project.
And it later results in software hang and crashing . even after a quit (force quit) and re-poen, it seems to happen again and again.
Even after a system reboot seems to be fine at first, but it still crashes on the project.
Tired to render the timeline and still the same. Also tried to delete rendered file and play right with timeline with yellow bar, same.
Even drop the preview playback to 1/2 and still..
files are mixed 1080p footage from Canon 5d3, 60D, T2i.
I have 3 layers (interview video with different angles) and a title layer (hard subtitle)
had some light color correction with fast color corrector and a sharpening on the 5d3 layer.
Ive work with the CC premiere pro before with mac pro and everything is fine and never hand an issue.
All my memory setting are set for performance and i have open GL on my D700s
Im not sure if this a software issue or someone my hardware is not working right?!
Thanks in advance!

I am having the same issues.
Im working on a late 2012 iMac, 3.4 GHz Intel Core i7. 32 Gb ram, NVIDIA GeForce GTX 680MX, OS X 10.9.4.
I'm editing RED footage, about 3 TB worth for this project from a Promise Pegasus drive.
The software really slows down when using the TYPE tool and also when scrubbing through footage.
When I attempt to quite the software and restart, the interface goes away but the app is still running but says "not responding" when I attempt to force quit.
If you've figured it out since then Id love to know what works.
Thanks!

XAVC 4K playback performance on Mac Pro

2009 Nehalem 2.66GHz 8-core Mac Pro with 16GB RAM and GTX570, running OS X 10.8.5.
As part of my freelance post work, I've started tackling 4K XAVC-I footage from the Sony FS7. The footage loads alright, but is impossible to play without serious stuttering. Brand new project. I tried any playback resolutions between full and 1/8, same behavior. I can't play a single second without the drop frame indicator going orange and starting to rack up dropped frames.
CPU utilization during playback is steady at 70%, and drive reads are at 80MB/s (our SAN successfully delivers 350MB/s).
Tried both Premiere CC and CC(2014), same behavior.
Performance in DaVinci Resolve doesn't look much different.
It's going to be a week or so before I'm back at the machine, so I'm preparing my attack plan. "Gotta buy a new computer" is the easiest possible answer but also the most expensive (we can all predict the boss` reaction) and not necessarily accurate one. Maybe it is the right one, but part of my job is to eliminate other possible (and cheaper) causes first.
What is the current state of 4K playback in Premiere? Is it two camps of "always worked for me" and "never works for me"? Has anyone had playback issues that were fixed by updating CUDA drivers, Premiere patches, identifying odd bugs, etc.?
I'm going to play with the video output, Mercury settings, source drive, and transcode to 4K ProRes at different bitrates... any other suggestions?
We all know that the new black Mac Pro "can do 4K", but I haven't heard a statement that "no other Macs can". Surprisingly, I haven't found discussions (let alone official recommendations) of minimum hardware requirements for Premiere and 4K. I'd be happy to be pointed to any if they exist. The CPUs in this 2009 Mac Pro should still pack more punch than any iMac model in the market, and is 25% slower than the baseline 2013 MP. If it's the GPU, I'd be happy to hear at least one testimony like "never worked with my GTX570 but once I went GTX680 I finally set sailing".
Thanks!

I use a Sony Notebook with 4 K Display and a USB 3 disk 2TB with footage from the FS 7, sequence lenght 3 hours and I have no problems. All is working very well.

CS2 performance on Mac Pro vs G4 based computers

I'm currently using a Powerbook G4 1.5 with 512mb. I am having a hard time using Photoshop because I've been working with really high resolution scans lately. I'm looking for someone who has both a Powerbook and a Mac Pro 2.66ghz, I would like to know whether or not moving up to a Mac Pro would speed things up for me since i'm on a G4. I know that the Mac Pro runs Adobe CS2 slower than the G5, but the G4 is a much slower processor than the G5 and my Powerbook has a 4200rpm drive. Any input would be greatly appreciated, I'm off to an Apple store for more info from a Genius, but I'd like some input from someone who uses both on a regular basis or something like that.
Thanks

My somewhat educated guess is that photoshop on the MacPro will be faster. The much faster cpu speed will offset the performance penalty of Rosetta.
I'd recommend at least 2gig but more like 4 gig, as that seems to be the sweet spot for photshop running on intel macs.
Take a look at these Benchmarks Actually the whole article is very informative.

FCP Performance on Mac Pro

Hi! After 3 months of pushing, I finally got a Mac Pro 2.8ghz 8-core with Final Cut Studio 2. I just got the workstation setup and Final Cut Studio installed, all the updates are completed. Now I am getting down into some light training with some DV footage I have to familiarize myself with the capabilities of this system. So far I have not been impressed. I imported 2 30-sec DV clips, dropped them into the sequence with crossfades, and when I playback, I hear 2 seconds of audio followed by beeps, and at the point where the clips are supposed to cross-dissolve the playback stops with a warning that frames have been dropped. I had better performance with iMovie on my G4. I know that FCP is a bigger beast but having worked with Avid MC on a PowerMac 9600 I am expecting more out of this setup. What in the world could I be doing wrong?

When I open the .dv clip in Quicktime it shows format: DV, 720x480 (640x480), Millions, Stereo, 48.000 kHz. What else should I check?
Ahh, I think I see your issue - and it's something that many folks who are moving up from iMovie experience.
Basically, FCP doesn't like .dv files. It likes .mov files. Open up you .dv file in QuickTime and export it out as a QuickTime movie (a .mov file). Be sure to select the Options... button in the export dialog (since you're bound to be overwhelmed, use the settings from your FCP Timeline as a guide) in QuickTime. Using the default settings in QT will not help you (the default is meant for web sharing, not editing, and will end up being step backwards).
In the future, avoid using iMovie captured material in FCP. Capture and digitize using FCP. Don't ask me why Apple decided to do this, but you cannot simply port your files from iMovie and get them working in FCP without a lot of hassle.

Best hard drive performance on mac pro for final cut express

This week I'll be setting up a basic 4 core mac pro with 16 gb ram and 2 internal- 2tb WD Caviar Black drives. I'm wondering what would give me the best performance for running final cut express, and I'm considering setting up software raid 0 or using one drive for boot and one for scratch. Or should I set up software raid 0 with boot and scratch partitions? Or other suggestions? Thanks.

My recommendations -
With 2 drives in your Mac Pro, use *one disk for OS X and all of your apps;* the *second disk for data* (including your FCE scratch disk location). Partition each drive as a *single partition,* which will maximize performance over time.
In addition, you should invest in at least 1 external drive to use for backup purposes; if you don't, the day will come when you wish you had.
I strongly recommend AGAINST doing software RAID. Certainly not for your situation with only 2 drives, one of which will be your system HD; but also because hardware RAID is faster, more reliable, and does not require CPU resources to run.
Your internal SATA drives will provide plenty of performance for most video editing needs. You also have the ability to put 4 drives in your Mac Pro, in which case you can utilize the extra drives to provide additional performance if/when you get into serious multi-multi track video compositing.

Slow Performance On Mac Pro 12-Core

Hello Everyone,
I just recently purchased a 2012 Mac pro 12-Core and i have been getting unbelievabley slow performance with it. I am using Premiere Pro CS6 and it seems that the footage can sometimes get a bit laggy at times and not play back smoothly, sometimes rendering can take a bit of time as well. However here are the specs of my system:
Mac Pro 12-Core 2.4GHz (2.67GHz Turbo Boost)
40GB of Ram
ATI 5770 Graphics Card
1TB scratch disk (with a user on the drive that i can boot into)
OCZ 120GB Vertex 3 SSD OS/APPS drive
First question i would like to get answered once and for all.. Did i make a bad decision by purchasing a computer with such a slow clock speed (2.4GHz)?? I figured since The new editing software is switching to 64bit it shouldn't depend on clock speed anymore? (i just want to be sure that i purchased a more than capable machine) However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month. (I dont have the budget to buy a Raid controller yet to utilize 6GB/s transfer speeds, so 1 Fast SSD drive will have to do for now)
I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance? Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too? Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere.. (the footage was in a crappy .M4P format, so that may have affected it, but I dont know)
Any suggestions are greatly appreciated!
-Thanks in Advance!

The new editing software is switching to 64bit it shouldn't depend on clock speed anymore?
Wrong, clock speed is everything.
I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance?
No, not really.
Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too?
When fill rates go up, performance goes down. With almost 90% fill rate, the disk performs only at around 50% of a new disk.
Two disks is absolute bare minimum, and your cores will constantly be waiting for the disks to read or write data, sitting idle most of the time.
Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere..
GoPro material requires a very fast computer, which yours is not with the low clock speed, outdated E5620 CPU's, only two disks, and a non-CUDA capable video card.
Take a look at the PPBM5 Benchmark and look at the system at rank # 854, which is a MacPro, very similar to your system, dual E5620, AMD video card, less memory but uses three disks.
So, your system would be around the same rank as the one above, among the slowest 25% of all systems and something like 10 - 15 times slower than a fast system. You tax your system to the extreme with the GoPro Hero3 material, and the consequence is the slow performance you see.
Sorry, not much you can do, other than get a new system. If you sell it now, it may get you a price, good enough to get a much faster Windows system and maybe even keep the change. Simply said, you bought a MacPro for € 3.5 K, sell it for € 3 K, buy a PC for € 2.5 K that is around 5-6 times faster and your loss is recovered.
However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month
What a pity the MacPro does not have SATA 6G ports, only SATA 3G, because then that SSD will run at almost half speed.

Turning Off CPU Cores - Cooler Mac Pro?

Using a Mac Pro in a small room raises the temperature of the room quickly and it is always hot. Does turning off 7 cores (leaving 1 available) using the CPU menubar utility make the computer run cooler? Is there anything else I can do to make the Mac Pro not run as hot?

I hope you didn't think we were being dismissive. I work in a small room on the top floor of a house which even if the house itself and the weather outside are very cool, my Mac room is too hot to stay in. So for me AC and a fan are the only options. The AC for both of us, the fan for the Mac.
I've never heard of someone trying to disable their machine in the way you are wondering about. Perhaps it can be done but just how many CPU's would you have to disable for a heat decrease? And what effect would that have on your overall system, health and performance-wise?
Then what about the heat from your display? That adds in too.
Maybe like me you can't put a regular AC in your window. I had to get something along these lines, which is noisy but works great for my needs:

Display issues, Mac Pro

Just got my Mac Pro, and it has a pretty frustrating problem. When waking up from sleep the display (ACD 20") stays black and there's no way of getting a signal without rebooting. If that wasn't annoying enough, the same thing happens about 7-8 times out of 10 when I reboot. The computer boots just fine, but the display stays off. I've tried with other displays and get the same problem.
This is a list of the things I've tried so far:
1. Called Apple Support, who wanted me to send it for a repair which seems kinda sad seeing as I've only had it for a few days. No replacement will be given though. Unfortunately Apple in Europe aren't as generous with the 14-day DOA period as they are in the US.
2. Reset PMU/PRAM/NVRAM (sometimes brings the display back up, sometimes not).
3. Removed and reinserted graphics card.
4. Removed and reinserted memory sticks.
5. Tried a new set of memory sticks.
6. Reinstalled OS X, which is the first thing I do whenever I get a new Mac anyway.
7. Tried different monitors with both ports on the graphics card.
8. Ran Apple Hardware Test without any errors registering.
Anyone have any suggestions of anything else I should try, or should I give up on this one and get it fixed?
Thanks

Arrow Key issue Mac Pro 15 inch

I own Mac Pro 15 inch running with Lion OS, for some days it stop responding to Arrow keys. However arrow key are working upto certain extent with the combination of command and control keys.How I can get this issue fixed?

If it says MacBook Pro under the screen, that's the name of the machine. Mac Pros are desktop tower computers. Arrow keys can sometimes malfunction if something gets in the keys, or one of the Apple menu -> System Preferences-> Universal Access settings gets turned on.

X230 CPU performance issue on AC power without battery

Dear Lenovo & Community Members,
I've recently received my X230 (model no.: 2320-24B), and discovered an issue related to the CPU performance of X230 on AC power. To make the long story short, my X230 is not running at full performance on AC power with battery detached. Accordingly, the X230 was shipped with setting at "Maximum Performance" under "Intel Speed Step" in BIOS by default on AC power.
Full Story:
My notebook is X230 (model 2320-24B) which comes with Ivy Bridge i7-3520M. I have a habit to detach the battery when it was fully charged, as I want to reduce the battery aging and my job does not always require me to work on the go. And by accident, I've discovered that X230 performs differently on AC power with and without battery. To be more precise, when my X230 runs on AC power with battery detached, it runs as slow as my Sandy Bridge i3-2100 desktop, which sounds very weird to me for a notebook costing me more than $1000.
Accordingly, I've benchmarked my X230 and here are the results, both with BIOS setting to "Maximum Performance" under AC Power:
AC power, without battery - WEI CPU Score: 4.9, WinRAR 4.2 benchmark: ~1,900kb/s, CPU @ 1.189Ghz on load
AC power, with battery - WEI CPU Score: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
On battery power - WEI CPU: 7.2, WinRAR 4.2 benchmark: ~4,000kb/s, CPU @ 3.6GHz on load
Based on my tests, I’ve found that X230 is only performing at maximum performance when attached with its battery, and it is underperforming at its lowest clock speed when not being attached with the battery.
Conclusion:
I would like to ask if other owners of X230 in this community have the same problem (and are able to repeat my findings). I'm quite disappointed to find that my X230 is running even slower than my i3-2100 desktop, and it simply doesn't make sense for a notebook with removable battery yet unable to run at full performance without battery. I demand Lenovo to address this issue.
- Joseph (PhD Information Systems)
Edit: I'm already running the latest BIOS 1.12
Solved!
Go to Solution.

Hi slkong, welcome to the forum,
allow me to assume that you have the 65W AC power supply. If this is the case in order to reach full CPU performance you do need to have the battery attached, there are several threads on this within the boards concerning different systems and also this Knowledgebase article.
Hope this explains the situation for you.

CPU Performance Issue

We are facing a performance issue related to cube refresh. Even a small cube consumes around 70% of the CPU while refreshing.
Details of the cube: This cube has 10 dimensions and 46 straight forward measures (mix of sum and avg as aggregation algorithm). No compression. Cube is partitioned (48 partitions). Main source of the data is a materialized view which is partitioned in the same way as the cube.
Data Volume: 1200 records in the source to be processed daily (almost evenly distributed across the partition)
Cube is refreshed using: DBMS_CUBE.BUILD(<<cube_name>>,'SS',true,5,false,true,false);
Environment - Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 (on AIX 6.1 64 bit), AWM - awm11.2.0.2.0A
Hardware Configuration
4.2 GHz, 3.5 CPU Core 32 GB RAM
Has anyone faced similar kind of issue? Is there any server level / database level parameter that needs tweaking to control this behaviour?

Here is another trick to combine sum and average measures in the same cube. It relies on the AGGCOUNT function in OLAP DML, which you can look up in the reference guide.
Suppose that you have a cube with two measures, A and B, and that you want to aggregate A using SUM and aggregate B using AVG.
Step 1: Make the cube be compressed and aggregate all measures (A and B) using SUM.
If you do this using AWM, then the solve specification should include a MAINTAIN COUNT clause. To double check, look at the user_cubes view for your cube (TEST in my example).
select consistent_solve_spec from user_cubes where cube_name = 'TEST';
CONSISTENT_SOLVE_SPEC
SOLVE
SUM
    MAINTAIN COUNT
    ALLOW OVERFLOW
    ALLOW DIVISION BY ZERO
    IGNORE NULLS OVER ALL
)You can hand edit the XML for the cube if this hasn't happened. Here is what you want to see in the XML for the cube.
    <ConsistentSolve>
      <![CDATA[SOLVE
SUM
    MAINTAIN COUNT
     OVER ALL
)]]>Don't worry about the slight difference in syntax -- this is due to different printing routines in the client Java and the server c code.
Step 2: Verify that the cube's VARIABLE has the WITH AGGCOUNT option.
My cube is named TEST, so the variable is named TEST_STORED, and my cube is dimensioned by TIME and PRODUCT. You can run this in the OLAP Worksheet.
dsc test_stored
DEFINE TEST_STORED VARIABLE LOCKDFN NUMBER WITH NULLTRACKING WITH AGGCOUNT CHANGETRACKING <TEST_PRT_TEMPLATE <TEST_MEASURE_DIM TIME PRODUCT>>
Step 3: Define a new Calculated Measure, B_AVG, in the cube to get the average for measure B.
Select "OLAP DML Expression" as the "Calculation Type" and enter the following expression. Obviously you need to adjust for the cube and measure names. I am putting new lines into this for readability.
QUAL(
NVL2(AGGCOUNT(TEST_STORED), TEST_STORED / AGGCOUNT(TEST_STORED), TEST_STORED),
TEST_MEASURE_DIM 'B')
Step 4: Specify the $LOOP_VAR on the new measure
Execute the following in the OLAP Worksheet. (Again, correct for measure and cube names.) It instructs the server to loop the cube sparsely. If you don't do this, you will get dense looping and poor query performance. You only need to do this once (per calculated measure). If you save the AW to XML after this, then the LOOP_VAR value will be saved in the XML itself.
call set_property('$LOOP_VAR' 'TEST' 'B_AVG' 'TEST_STORED')For reporting purposes you should look at measures A and B_AVG.

Graphic issues mac pro

Distorted imaged on HDTV

I'm not sure if this is related or not. A client of mine is using a MacPro (Late 2013 - 32GB RAM - 6 Core) with a Samsung 4K display. The problem began recently in Mail, he get's the spinning beach ball constantly, making Mail useless. Only Mail is affected and I have gone thru all the Mail fixes (rebuilding, reindexing, recreating account, creating new user account, etc...) to no avail. If I log in with TeamViewer, the problem instantly corrects and no issues as long as I stay connected. Once I log out, spinning beach ball. No processes in Activity Monitor or TOP indicate anything running amok. Since the problem seems to go away with TeamViewer (not VNC or ARD though) I assumed it might be display related. After some experimentation, changing the display resolution to another setting and back again fixes it for a bit. I assume it's a problem with the graphics adapter working with the 4K display but am wondering if others have seen this or know of a possible fix? I've seen posts about the Mac Pro's 4K problems with certain displays but not this specific issue.
