Add to that that i have latest i7 - 8 core. My computer is acting super stable and slick fast for other apps even other DAW applications. It's just that live 9.5 is kinda nightmare for me...
So go back to 9.2. I maintain that 9.5 massively increased my performance on my old core2duo and causes no issues whatssoever on a quad core 17 system. If 9.5 generally gives better performance on some computers there must be a reason why it doesn't do this on yours.
9.5 experience vary and neither of us can draw definite conclusions from posts. Generally people without issues tend to not read about problems nor post about them. As I've already said, I agree these kind of issues need to be fixed.
You don't seem to have analyzed CPU usage in your case. If you do that you can see if that's something likely to be behind these issues of yours that can be fixed with OS downgrade/upgrade or throw more CPU on it.
All of the following may appear to be outside of specific issues with 9.5, but I think it's likely to be related to crackle and glitches problems. Of the three OS X machines I've operated 9.5 on, none have gotten worse because of 9.5 and definitely better in one at least.
Different types of issues
What I and several have noticed as severe issues are of two types, that might not be exclusive.
One being, crackles, glitches or both
when CPU does not appear to be taxed in analysis tools,
nor does increased latency help much, if at all. In my case it typically gets worse at higher settings and I need to stay at 128-512 samples. This issue cannot be solved with more CPU power, unless it's spikes in one system that does not occur in another. I suppose this is the most likely with your machine. Noticing something in the description?
The other being
when CPU is indeed under heavy use, at least in one core, either from Live and/or from other processes running on the machine.
Other processes can affect the first type of issue too, especially with CPU spikes. A symptom here will be that
increased latency does help as do throwing more CPU on the problem. This is where you have to decide to either get a faster machine or change DAW. In your case a faster machine may not seem to make sense, but remember to investigate all aspects of your system.
Third party plug-ins and multi-core
Typically problems like these can come at certain parts of a song and
involves certain plug-in use. These could be an indicator with issues connected to these plug-ins. In my case it's Native Instruments. This can possibly be explained by CPU spikes caused by these plug-ins that takes an individual core trough the roof, which is bound to cause crackles. Possible solutions could be to either turn off multicore support or turn it on in the specific plug-in.
Other DAWs doing better could be because of being better with multicore support overall or for catering for multicore use of used plug-ins.
CPU Spikes
CPU spikes may be behind a lot of these issues and that will vary with different models of CPU. Intel Speedstep switching may be behind such spikes in some cases. Unfortunately I have yet to hear about a way to analyze these well in OS X.
Possibly you can use
Intel® Power Gadget for Mac and get some info. I haven't had the reason to use this on a supported system. In Windows this should be easier to analyze, so maybe it's very useful for all users if Windows users do this type of analysis of common third party VSTs as well as with Live.
