Speed and performance FAQ
If PortableMind feels slow, these FAQs will help you tune ports, presets, cache, and antivirus so the offline AI stays quick.
Ports and hardware
Best port to use?
USB 3.x or quality USB-C adapter; avoid unpowered hubs and loose ports.
Does free space matter?
Yes. Keep 10–15 GB free on the USB for cache and updates.
Laptop overheating?
Use low-spec preset, reduce stream speed, and keep the device ventilated.
Presets and prompts
When to use low-spec preset?
On 8 GB RAM machines, on battery, or when you need quiet operation.
Why are responses lagging?
Prompts may be too long; shorten them, cap tokens, and close extra tabs.
Can I speed up token streaming?
On strong hardware, increase stream speed; on weak hardware, lower it to reduce stutter.
Software factors
Antivirus slowing things down?
Add a scoped exclusion for the USB; keep protection on elsewhere.
Browser extensions causing issues?
Try a private window or another browser without extensions.
Cache problems?
Clear cache for localhost if the UI hangs after updates.
Benchmarks and drills
Should I benchmark?
Yes. Time startup monthly so you notice regressions early.
What if performance drops suddenly?
Reseat the USB, check free space, and confirm exclusions are active.
Is plugged-in always better?
For heavier models, yes. Low-spec tasks can run on battery.
