    High-concurrency uploads: raise the libuv threadpool size (UV_THREADPOOL_SIZE=64) so file reads and DNS lookups for many simultaneous uploads no longer serialize through the default 4 threads — this targets lag that appears from a certain number of concurrent connections onward. Also adds an event-loop-delay metric (perf_hooks) that is logged while uploading, to pinpoint whether high-concurrency lag is CPU-bound (needs workers/cap) or IO-bound (needs threadpool/socket tuning).
