leo thang, engine.log co engine moi moi ~2.5-3.3s trong nhieu phut.
Goc re: app/core/vst_engine.py module-level:
HAS_PEDALBOARD = check_pedalboard_safe()
-> subprocess.run([sys.executable, '-c', 'import pedalboard'], timeout=2.0)
Khi frozen, sys.executable = daw_engine.exe. PyInstaller bootloader bo qua
'-c' va chay script nhung (desktop_engine.py = CA ENGINE) -> moi lan check
thu vien lai khoi dong mot engine moi (timeout 2s moi check, block startup
~4s) -> engine con import app.main -> lai chay check -> spawn tiep
=> de quy vo han, hang chuc engine, may nghen, load 6-7.5s.
Fix:
- vst_engine: check_pedalboard_safe/check_pyfluidsynth_safe dung
importlib.util.find_spec (micro-giay, khong spawn, hoat dong frozen).
- desktop_engine.main(): guard phong thu - neu bi goi voi argv[1]=='-c'
(dang bi dung nhu python interpreter) thi thoat ngay khong chay server.
Verify tren Linux (engine frozen):
- STARTUP: 6-7.5s -> 1.24-1.33s (3 lan lien tiep)
- sau 15s: dung 1 engine, 0 process '-c import' (truoc: hang chuc)
- 86 tests pass; test suite 34s -> 14s (may het bi spam).
