You may hear that Lutefish works best within roughly 500 miles between participants.

This is a useful guideline — but it is not a hard limit.

Some connections work well beyond that distance, while others may struggle at shorter ranges.

Why Distance Matters

Even though internet signals travel very fast, they still take time to move between locations.

For real-time music collaboration:

• Every millisecond matters

• More distance usually means more latency

As latency increases:

• Timing feels less natural

• Playing tightly together becomes harder

Internet Quality Matters More Than Raw Distance

Two people 800 miles apart on excellent fiber connections may perform better than two people 100 miles apart on poor internet.

Performance depends heavily on:

• Internet type

• Signal routing

• Network congestion

• Number of server hops

• Equipment quality

Fiber vs Cable

Fiber (Best)

Fiber internet usually provides:

• Lowest latency

• Lowest jitter

• Most stable routing

This gives the best chance for successful long-distance sessions.

Cable (Often Works Well)

Cable internet can still work very well.

However:

• Latency is usually slightly higher than fiber

• Performance may vary by neighborhood congestion and ISP routing

Many successful Lutefish sessions happen over cable connections.

Internet Types That Usually Do Not Work Well

These connection types typically have too much latency or jitter for real-time music:

• 5G home internet

• DSL

• Satellite internet

They may work fine for:

• Streaming video

• Video calls

• General browsing

But real-time music collaboration is far more demanding.

Server Hops & Routing Matter

Internet traffic does not always take the shortest physical path.

Sometimes your signal:

• Travels through multiple cities

• Passes through inefficient routing paths

• Encounters congestion along the way

This means:

• Two nearby cities can occasionally perform poorly

• Two farther-away cities can sometimes perform surprisingly well

Distance is only part of the equation.

Playing Style Matters

Some musical styles tolerate latency better than others.

More Sensitive to Delay

• Tight rhythmic playing

• Fast groove-based music

• Percussion-heavy performances

More Forgiving

• Ambient music

• Slower tempos

• Looser improvisation

Results Can Vary

Because every internet connection is different:

• Results vary from user to user

• The 500-mile guideline is simply a practical estimate
