Are you running linuxsampler as a plugin inside of QTractor, or running it as a separate process connected via alsa sequencer API?
Because that could make a big difference in the resulting performance.
In other words, which of the follolwing methods do you use:
============================
I select QTractor's "Track -> Add Track..." menu command.
This pops up a dialog to enter the new track's properties. I select "MIDI" type of track. I check "Omni". Then I select the "Plugins" page, click the "Add..." button, and find/select the "Linuxsampler" LV2 plugin. I also check "latency compensation".
I click OK to dismiss the dialog and create my new track.=============================
I run QSampler or Fantasia to start Linuxsampler.
I run QJackCtl, and click the "Connections" button.
I go to the "ALSA" page, and I connect QTrackor's MIDI Out to LinuxSampler's MIDI In.==============================
You want to do #1, not #2,
Muse and Qtractor could both do with a folders feature
Muse has a group of 7 pushbuttons that allow you to set which types of tracks to show/hide. If you position the mouse cursor over the first button, a (yellow) tooltip will pop up that reads "Show midi tracks". If you click on this button, it will change to a dimmer color, and all the MIDI tracks will disappear from your window. They're still there, and they still play, but they're no longer shown in the window. If you click that button again, all the MIDI tracks reappear. You have 6 more buttons to show/hide other types of tracks. If you want to hide all of the plugins, click on the "Show synth tracks" button. (It's the rightmost button).
I'm pretty sure qtractor also has a way to hide/show tracks. But I don't know it offhand.
I run LS as a separate standalone process and Qtractor midi out to LS's midi in. I also do the same with Muse. So there's no plugin process going on inside either app, just midi connections.
I know about Muse pushbuttons, but they're for track types, not groups of midi tracks, for one example. I have hidden all the track types, except midi.

Create a folder. Add what ever tracks. These could be all the woodwind tracks, or all the articulation tracks for 1st violins, for just two examples. That's what I'm referring to when i suggest folder tracks. Close the folder when you're not working in it, and open when you are.
