DP very bogged down until song is Playing

[cbergm7210]

Here's a new one just figured out. At the end of projects DP invariably gets bogged down from all the plug-ins and such, acting super slow to the point of pulling hair out which can be frustrating to say the least.

Today I accidentally noticed that DP went back to acting instantaneous as long as the song was playing. I suspect it has something to do with plug-ins running in real time or not etc. Either way, this will save much time as mixes are completed in the final hours. Tweaking automation and other things will now be as fast as it is in the beginning stages of projects.

I have no idea why this works, but if it saves time for others I figured I'd post it to the Motunation brotherhood.

Thanks for posting. This might explain some issues I've been facing lately.

My new SSD arrived today though, and DP 9 should swing by on Friday, so along with an upgrade to Yosemite later this week, maybe I'll be in Happy Heaven even before following the advice in the video.

I'm just thinking out loud here, CB, but it might be worth taking a look at the three settings I haven't looked at in years, Work Quanta, Prime Seconds, and Max Work Percent. A few years back I spent a whole day trying to quantify how these setting related to performance.
Do they interact? - Don't know.
Are there settings better than what I finally chose? - Don't know.
Do they have an impact on performance? - Absolutely.
Even after twiddling for so long (quite systematically as I recall), I came away with only a vague sense of what these settings really do.
I don't know if changing these settings can improve performance while nothing is playing, but it might be worth investigating.

Thanks Phil Man. I'll check those again for sure. Although I've twiddled myself on these parameters not a little in the past.

What I find completely revealing (about whatever is going on behind the scenes in DP that I have no clue) is the difference in how DP is acting on my system between playing and not playing. Bogging down almost to the point of ridiculous when not playing, then acting spot on, incredibly "snappy" when playing. Gotta be a bottleneck somewhere.

I bring DP to its knees regularly like this so for whatever it's worth I'll take the workaround.

Any of ya'll drag DP down to the point of one to three seconds between clicks of the mouse? If so, I'd be curious to see if it reacts better when playing the song as in this case.

Your suggestion is easy to test. Just turn off Pre-Gen in the Plugins preferences.

Yes, I have things set at Real Time. Thanks for the reminder.

Did that work?

Sorry...plug's were already set to Real Time, no pre-gen coming into play here.

Yuck. I haven't come across that one before. I wonder if there's something wrong with Background Processing in your setup. It's as if DP stops chewing on something on play to allocate resources to playback, then goes back to it's gnawing again when stopped. Have you tried watching Activity Monitor while stopped and playing back? I'm curious if the CPUs or GPU are pegged when it's sluggish.
