Custom workspace = slow HISE

[Dan Korneff]

your custom workspace json just makes HISE crash over here.

@dustbro How did you load it?

[Dan Korneff]

@d-healey I take that back... Accidentally deleted the config instead of replacing

I dropped it into AppData/HISE on my pc and HISE appears to be working properly. I don't notice any sluggishness.

[d.healey]

Did HISE load up at normal speed? That's where I'm noticing the most slowness.

[Dan Korneff]

@d-healey I didn't notice a difference.

[d.healey]

@dustbro Hmm, must be something else with my config then. Thanks for testing it, enjoy your new custom workspace :p

Do you have any markdown panels in your layout? Because they will initiate a "hidden" HISE instance for the dynamic help things.

[d.healey]

@Christoph-Hart I don't have one in the custom workspace but I do have a markdown editor tab in the scripting workspace. I've just removed this and relaunched HISE and the slow startup issue was still there.

I tested renaming my editorData.json and HISE opened up (with default layout) and normal speed.

Unrelated, but I also noticed that load JSON is greyed out when you right click on the top level of the custom workspace

Has the current project a lot of sample maps / midi files? They are initialised on startup so it might be the reason if you are working on a big project (Percx as about 1200 samplemaps and Midifiles so it takes 3-5 seconds if I start HISE with the percx project).

[d.healey]

New empty project here, 8 - 10 seconds to open. Maybe a GNU/Linux only issue?

[d.healey]

I just tested on Windows and no problem there so I think it's specific to my OS and possibly to my general setup. I'll try on my other GNU/Linux system.

[d.healey]

Definitely seems to be OS specific, I just tested on Linux Mint and had the same issue as my main Debian system.

[d.healey]

Just tested on MacOS, works fine...

Try compiling the plugin version of HISE and then load it in a DAW and close reopen the window. If the lag is also happening there you know it's something related to the UI.

[d.healey]

@Christoph-Hart Good thinking, I'll do that now

[d.healey]

The plugin version doesn't seem to read from the same editorData file as the standalone version. Each time I open it it's reset to the default layout, even if I make changes to the layout in the plugin.

[d.healey]

@Christoph-Hart I've narrowed it down. When I remove the API browser from my custom workspace everything works normally.

[d.healey]

I'm digging up this thread again. I posted another thread recently where I mentioned HISE was laggy and I thought it might be down to Alder Lakes E/P cores. But I disabled all the P cores and it didn't make a difference.

So then I started wondering if it was the issue in this thread and it was caused by the API browser now being present in the sidebar. So I commented out the source code where that API browser is added, and bullseye, HISE opens instantly. It also closes instantly now too, I never noticed that was lagging also.

So @Christoph-Hart when you have a moment, please see if you can find out why the presence of the API browser causes HISE be super laggy on Linux.

[d.healey]

I've looked into this further and the issue is related to the help text generation. If I comment out this line, HISE loads up quickly (but obviously I get no help text).

Could this data be cached so it doesn't have to recreated everytime HISE is opened?

[d.healey]

@Christoph-Hart Got any ideas about this?
