Maximum TCP Connections per Server Process and per Server

A single server‑side process can theoretically handle up to 2^48 (≈2.8×10^14) TCP connections, but Linux file‑descriptor limits and memory consumption (about 3.44 KB per connection) restrict real‑world capacity to a few million connections per 8 GB machine, while a whole server’s total is bounded by the same resource constraints despite the much larger theoretical maximum.
