Which is more CPU intensive?

Which is more CPU intensive, tracking to an audio track and looping that, or using Logic vitual midi instruments? Plug-ins and automation on audio tracks or Logic virtual midi instruments? Third party plug-ins like Waves or Izatope or Logic plug-ins

A bit hard to answer, as you need to be a little more specific, but generally:
tracking to an audio track and looping that, or using Logic vitual midi instruments?
Depends on the instrument - Ultrabeat or Sculture can be pigs, for example, but generally recording audio tracks (lots of them) will tax your hard disk more than CPU.
Plug-ins and automation on audio tracks or Logic virtual midi instruments
Again, which plugins? Some hardly make a noticeable difference, others like Space Designer can get intense. Automation - very little.
Third party plug-ins like Waves or Izatope
Don't use Waves, but Izotope Ozone 3 is a real hog - but worth every bit of it - I love that plugin.

Is merge join cartesian more cpu intensibe than nested loop ?

Hi,
just wonderning which access method is more cpu intensive , lets supposed we got 2 the same row sources and doing joing via merge join cartesian and next case is nested loop .
I know NL can be cpu intensive because of tight loop access , but what abour MJC ?
I can see bufferd sort but not sure is that cpu friendly ?
Regards
GregG

Hi,
I think in your case it's more accurate to compare a NESTED LOOP (NL) to a MERGE JOIN (MJ), because CARTESIAN MERGE JOIN is a rather special case of MJ.
Merge join sorts its inputs before combining them, and it could be efficient when one or both of inputs are already sorted.
Regarding your question (which is more CPU intensive):
1) if MERGE JOIN involves disk spills, then CPU is probably irrelevant, because disk operations are much more expensive
2) the amount of work to combine rowsources via a MJ depends on how well they are aligned with respect to each other, so I don't think it can be expressed via a simple formula.
For nested loops, the situation is much more simple: you don't need to do any special work do combine the rowsource, so the cost is just the sum of the cost acquiring the outer rowsource plus the number of iterations times the cost of one iteration. If the data is read from disk, then CPU probably won't matter much, if most of reads are logical ones than CPU becomes of a factor (it's hard to tell how much work CPU will have to do per one logical read because there are two many factors here -- how many columns are accessed, how they are located within the block, are there any expensive math functions applied to any of them etc.)

Ghosting on cpu intensive app

So I have a Flex app, which can be cpu intensive at times, with some ghosting issues ( see attached image ). I had this issue once before with just IE8 and textfields, but now its happening with everything in the swf and in every browser (Chrome, IE, FF). Even if you let the app sit after loading so the cpu slows down it still happens.
I ran a test when I had the text issue in IE8 (via Alex H.) where I took a bitmap snapshot of the screen from within Flex and it didn't show the ghosting in the bitmap.
I have a feeling this is an issue with the browser refreshing? There is a js call that you can use to force a screen refresh (not the webpage) but that didn't work either. Just wondering if anyone else has run into this issue?
TIA, Jason

Terpstar,
I was wondering if you have had a chance to use Motion yet. I have a MBP, and using Zapfino fonts with SciFi Glow crashes my system every time. I would be interested to see if this is the case on other intel based systems. This has led to a failure of my main logic board twice over the last month. See my thread:
http://discussions.apple.com/thread.jspa?threadID=614641&tstart=25
Also, of the two GB ram I have installed, FCP doesn't seem to utilize more than 100MB of RAM. Although the VM size is several GB for the app. I noticed that in order to utilize both cores on my MBP, Airport had to be turned off.
Also, as Ned Snowing was saying, there is no doubt that there are going to be many software bugs that must be sorted out. Especially since this program is being adapted for intel macs, and not re-written.

Mds eats more cpu even if there is no indexing at all.

Hi Guys,
I have been facing problem slow responce in macbook pro (13' , 2.5 GHZ dual core, 4 Gb RAM, mid 2012 model) and I could see mds process is taking too much cpu usage (60 to 100%), even if there is no indexing at all. The problem was there with Mountain Lion 10.8.3 as well, then upgraded to OSX 10.8.4 with hope that will sove it, but it did not.
I attached my Activity Monitor which shows more cpu usage of mds and that time no indexing also, This sluggish responce issue happens with few minutes, and during that time mds goes up. This sluggish problem kills my day to day work, every thing is **** slow now.
I read some of the discussions but nothing helped me, if any of you has the dame problem and if you solved it please help. or it would be so great if you can give me some tricks to solve this one.
Thanks....

I just spent the entire day chasing MDS running at 100+% CPU on my Early2011 MacBook Pro.
What finally SOLVED it for me was uninstalling LogMeIn. It was auto-starting itself outside of Apple's control systems and as soon as it started MDS CPU rocketed. As soon as I went into the LogMeIn preferences and selected "uninstall", the MDS CPU dropped back to less than 3%.
How I found it: (Presuming that the high CPU doesn't show up in SafeMode as mine didn't...) Boot the system in SafeMode by holding the shift key as it boots up. Log into the account that is having the problem. Start Terminal and issue the command 'ps ax > ~/ps-output-safemode'.
Reboot the system into normal mode. Log in to the problem account. Start Terminal and issue the command 'ps ax > ~/ps-output-normalmode'.
Then open a second terminal window next to the first. In one do 'cat ~/ps-output-safemode'. In the other do 'cat ~/ps-output-normalmode'.
Stare and Compare to see what is running in normal mode that isn't running in safemode. Hunt those apps down and shoot them all. Reboot. If the problem goes away, add them back one at a time rebooting between each to see which one causes the problem.

Use V$SESSTAT to determine which sessions are using most CPU, and investigate what SQL these users/sessions are executing:
SQL> select ss.sid, se.command, ss.value CPU, se.username, se.program
from v$sesstat ss, v$session se
where ss.statistic# in
(select statistic#
from v$statname
where name = 'CPU used by this session')
and se.sid=ss.sid
order by ss.value desc;

How to find which query taking more cpu

Hi,
How to find which query taking more CPU
at a particular point of time .
Chhers,

Take a look at Server Standard Reports. It has a few CPU usage oriented reports.
You can also track CPU usage by server-side tracing:
http://www.sqlusa.com/bestpractices/createtrace/
Glenn Berry's CPU usage query:
SELECT TOP(25) p.name AS [SP Name], qs.total_worker_time AS [TotalWorkerTime],
qs.total_worker_time/qs.execution_count AS [AvgWorkerTime], qs.execution_count,
ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second],
qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count
AS [avg_elapsed_time], qs.cached_time
FROM sys.procedures AS p WITH (NOLOCK)
INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK)
ON p.[object_id] = qs.[object_id]
WHERE qs.database_id = DB_ID()
ORDER BY qs.total_worker_time DESC OPTION (RECOMPILE);

Looking for Mac that can handle CPU intensive apps (Music & Video)

Hi everyone, I am looking to get a new mac in the near future but wanted to know which Desktop mac is best for music and video? I was thinking of the new iMac but not sure if they are powerful enough? I need something that can handle CPU intensive stuff. I will be using it mainly for video editing and music producing

In a nutshell,
Look at the new 27 inch screen iMac models.
Get the fastest optional CPU,
Decide which optional GPU you'd be comfortable with.
Get the base 8 GBs of RAM and then purchase extra, cheaper RAM through third party Mac RAM sellers.
Then add as much RAM as you think you need. The 27 inch screen models can take up to 32 GBs of RAM.
Decide on optional storage sizes.
If you need a CD / DVD optical drive, these are no longer built-in and you will need to budget for a good external optical drive.
Budget for 3-year extended AppleCare warranty service.
In case of reliability issues with the first 5 years of operational life, the iMac will be covered with free warranty service for the first three years.
Good Luck!

10.5.7. why so CPU intensive on PBG412"?

I just installed 10.5.7 on my PB G4. The CPU appears to be always maxed out, and as a result
my brand new battery which lasted 4hrs under 10.4.11 suddently dropped to just over 1.5 hrs.
Not to mention the computer is now hotter all the time.
Is there a way to moderate the CPU usage of 10.5.7?
Regards

If you just installed Leopard over Tiger, Spotlight will be indexing any and all volumes you have not excluded. This is an energy/CPU intensive process. See if the dot in the center of the spotlight magnifying glass is winkling. If so, it's still indexing.
Run Activity Monitor and look at the top processes.
Or run
top
in the terminal.

Urgt:How to identify TOP 5 SQL using more CPU time without using statspack

How to identify the TOP 5 SQL queries which are consuming more CPU time during the timespan of 24 hours for entire database. There are N number of users who have issued sql queries, out of which few users have disconnected and few user are still connected to the database(I need to consider all sessions). My database version is 9.0.1. I don't want to use statspack. Is there any way to identify TOP 5 SQL consuming more CPU time without affecting the performance of the database. Can any one help me on this? Its urgent!!. I don't want to use statspack becasue it degrades the performance and i cannot afford to run it for 24 hours.

You don't run statspack for 24 hours, that would infact be pointless...
Run statspack for say a 10 or 15 minute window during a particular "busy" period on your database. If you run it for longer then all the useful data will have been "averaged out". You want a snapshot in time, not an average over the day.

What does cpu intensive mean?

I downloaded free trial of adobe audition 3, when trying to remove vocals to make karaoke song a message came up saying cpu intensive
can anyone please tell me what this means, and the vocals where still there.
Thank you
mimsypoo

Thanks for all the info,
I tried remove vocals from various sources without success,so I guess
this programme isn't any good for what i am trying to do or maybe it,s me.
Thank you Mimsypoo

CPU Intensive warnings come up when using effects that are not suited for real-time use. This means it's fine to use the effect on a file where you don't mind waiting a few minutes for it to do its thing, but you wouldn't want to plug the effect into a track and try to remove vocals from a microphone you're singing into. It requires the computer to do too much calculation and it wouldn't be able to keep up.
As for why your vocals were still there, vocal removal is a very complicated procedure, and honestly more often than not, you won't get satisfactory results. When a song is mixed, often the vocal portion is placed in a very specific portion of the stereo field - usually right in the center so that both ears hear it equally. When this is the case, you can usually isolate and remove this portion of the audio if you can determine where in that stereo field it is located. Other songs, however, may spread the vocals out more broadly, process it with several effects that migrate around the stereo field, or even use multiple recordings of the same vocals in different locations. This makes it much more difficult, as close to impossible as can be without fully committing myself, to accurately remove the vocals without affecting a significant portion of the rest of the track.

A specific App needs more CPU

I have an EyeTV which displays live TV on my Mac. When it's in the background, it often skips and stutters. Can I allocated more CPU time specifically to that app? How?

There is no way to change the memory allocation in OSX. That is handled completely by the system.
Miriam is on the right track. Safari uses a lot of resources, not just memory. You are probably, when surfing with Safari, using Java, Flash, and other technologies that are all trying to share CPU time and memory. Something has to suffer. I imagine that EyeTV uses its fair share of resources also.
You also have to remember that you are using VRAM from your video card to make all of this happen. Maybe that is the weak link. How much VRAM do you have? Maybe you should investigate a more powerful video card.
