We’ve had multi-threading since version 1.5.4, and the number of threads you can run comes down to your hardware and internet speed: each "free" CPU core generally handles 5-10 threads, so a 12-core CPU can comfortably run 60-120 threads with enough RAM and bandwidth. If you’d rather not do the math yourself, AutoPilot adjusts your thread count automatically based on your hardware and current workload. See the Threads & AutoPilot docs. One note if you’re specifically using PPPoE, VPN, or phone mode instead of Dalga IPs/proxies: those change your whole machine’s IP, so multiple threads will share the same IP unless you enable Multi-Threading, which rotates the IP between session batches.
