TheBrain 9 Server Is Temporarily Down (Servers Upgraded)
Would you consider creating a status.thebrain.com page or a Twitter feed w/ status updates? (and previous) slow navigation and high CPU on OS X

I'm not sure why you're referring to the options menu. He says:

Quote: I clicked my mouse in the moment you a red circle. The animation of the circle gives you an impression how much time passes before the application switches to the next thought. To me, there is a significant difference between TB 8 and 9.

He's talking about slowness while navigating the plex which you can see in his videos and is same issue I'm having. I've mentioned the slowness specifically in the context of keyboard navigation since I think it's the easiest to repro, but it's the same with mouse use. I realize he's on Windows, I never implied the issue exclusive to macOS, it's just where I've experienced it. Apparently it's also a problem on Windows.

I could be wrong and we're having two separate issues, but that's not what it sounds like to me. Maybe André can confirm? (and previous) slow navigation and high CPU on OS X
I'm using a 2016 MBP w/ a 2.7ghz i7 and 16gb of ram on an SSD drive. It's not the machine. It isn't the case that v9 is sometimes slower than v8, or that it's slower after switching apps or with high memory pressure or anything like that. V9 is always slower.

André's videos are completely consistent with what I'm seeing. He and I are both making a direct comparisons by using v8 and v9 on the same hardware under the same circumstances and v9 is clearly slower. Running benchmarks etc., seems unnecessary given those parameters. (and previous) slow navigation and high CPU on OS X
Yes, you are correct, that video doesn't clearly capture the delay I mentioned, but the delay exists in normal usage. Sometimes it's quite small, other times it feels like it's almost a full second, though it's difficult to time it exactly.

Regardless of the exact timing, the point is that when using the arrow keys to navigate, there is a very noticeable lag between hitting a key and the focus changing or an animation starting. If it wasn't enough to be distracting, I wouldn't have never thought to post this, but as it is, it takes away from the seamless experience of using the software. (and previous) slow navigation and high CPU on OS X
Hi Harlan, I've set the animation speed to just under the fastest possible and taken a video comparing the two - v8 is on the left, v9 is on the right. The Brain 8 keeps up almost perfectly, while version 9 is inconsistent and almost always slower.

This has been the case since I've started using v9.
iOS version still not updated to use native resolution (#300)
Thanks Harlan. I've used The Brain 9 on Android a bit and, while it's a bit slow, it's very promising! Looking forward to a similar iOS experience. (and previous) slow navigation and high CPU on OS X

It's not a specific issue that would show up in an output log. Using the arrow keys to move between nodes is simply much slower in v9 than it was in v8. I'm certain this is the case on OS X, it may be the same other platforms, I'm not sure.

Repro steps:
1. Create a brain with 3 thoughts - one parent and two children.

2. Use the right and left arrow keys to navigate quickly back and forth between the two children.

The focus ring keeps up w/ key presses.

The focus circle lags and can't keep up the key presses.

iOS version still not updated to use native resolution (#300)
Can we expect the iOS version to get native resolution support any time soon? I love having The Brain on my phone but each time I open the app it feels like I'm stepping back in time... the whole UI feels pretty primitive. I appreciate the hard work the team is putting into these apps but it's disheartening feeling like it's always a bit behind the curve. (and previous) slow navigation and high CPU on OS X

I recently switched from 8 -> 9 and can't help but notice that moving the focus circle in the plex is much laggier than it is in 8. There's a 200-700ms lag before the focus indicator begins to move from one thought to another. 

Looking at Activity Monitor I see that the resting CPU usage with The Brain active, but not being used, is ~11%, then when I move focus, it jumps to ~30-50%. Both seem too high and the performance while moving around the plex is distractingly slow.

I'm using High Sierra on a 2016 MBP.

Error importing The Brain 8 file.
@spacenexus - thanks for your reply. I should be pretty good on disk space. My brain isn't all that big and I have ~15gb of free disk space. It looks like it's just some Java null check throwing an error in the importer. Based on the error text, I could probably delete something from my events if I knew what to look for... but I am not sure what it would be.
Error importing The Brain 8 file.
I'm using alpha on a Mac running OS X 10.12.6 and keep getting an error trying to import my version 8 file. Is there anything I can do? I'm ready to switch full-time to 9 and bummed that I can't get it running. I tried three times w/ a brain I've successfully imported in the past.

Trying to access a large WebBrain
I was unable to get it working uploading from within PersonalBrain. Uploads completed but it never showed up on the site. Creating a brainzip and uploading it worked though. It appears sync is working as expected too. My brainzip file is just under 1gb.

As a side note, I can't really use the web version under Chrome or Safari on OS X 10.6 latest versions of everything. Brains show up but it's difficult to navigate, it's as if the browser doesn't want to give the java applet focus or something. In Firefox it works fine.

Cool. Thanks for the examples. I should probably just keep leave it at that, but I can't help being a bit of a contrarian. At a glance it seems like a flowchart done in Visio or OmniGraffle would be easier and clearer than mapping flow in PB. And from personal experience, the expanded view in PB requires much more tweaking to get everything you want visible than the automatic layout you get with a mindmap.

I appreciate the information--I'm sure for some people PB is the best tool for the job for things like mindmaps, flow charts etc. Maybe I've just found my PB 'happy place' and I'm not really as willing to consider change as I tell myself I am.

I don't know, I still would use a mindmapper like Freemind to plan a vacation.

The vacation is finite - it has a definite beginning and ending which is where mindmaps excel--you start in the middle and work your way out.

The data around a vacation is, for the most part, is disposable. After the vacation I won't need flight itineraries or the scuba reservations. In my opinion that type of data just clutters PB but works well in a mindmap (maybe attached to a PB node). On the other hand, if I was a travel agent or researching somewhere I might visit several times I'd probably use PB.

Mindmaps are also better at showing me everything at once which I think I'm more likely to need for a trip.

PB is also, like you mentioned, much to expensive to purchase if planning trips and the like are to be the primary uses. I'd say focus on what PB does the very best and market other potential uses as perks. Just my thoughts from the peanut gallery

I am curious to see or hear about examples using PB for data/clickstreams/processes like you mention. Maybe I've seen it used for that before, but I can't think of a specific example. Do you have any resources I could check out?
