perf(fuse): optimize Linux mount options inspired by rclone#308
Merged
Conversation
Add FUSE mount options that improve performance on Linux: - DisableReadDirPlus: skip per-entry stat on directory listings - DirectMount: bypass fusermount helper for faster mount - MaxBackground 64: allow more concurrent async kernel I/O (default 12) - Default MaxReadAhead to 128KB when unconfigured - Increase fetch buffer pool from 256KB to 1MB for fewer allocations Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
