pub const MMAP_THRESHOLD: usize = _ /* 4_194_304usize */;Expand description
The fixed mmap threshold pin_mmap_threshold sets. Any fixed value
stops the growth; measured on a warm MCP server (9-page paper, 4 vCPU,
ONNX arena off) RSS held at ~475 MB with 1, 4 or 16 MiB against 500 →
750 MB without, and from 4 MiB up the conversions were as fast as
glibc’s default — at 128 KiB every ONNX intermediate tensor was mapped
and conversions ran ~8% slower.
