Why it matters

Allocations aren’t “free.” Each heap allocation:

(eventually promotions → Gen 2 → long pauses)

• Consumes CPU (for pointer bumping)
• Increases memory footprint
• Puts pressure on Gen 0 → more GC cycles

In low-latency systems (like trade execution or tick feeds), GC pauses = missed ticks or delayed quotes — unacceptable.

So the best GC strategy is often:

“Don’t make the GC do work at all.”
