For 4 KB page size, old FUSE_MAX_PAGES_PER_REQ = 32 meant 128 KB, which limits throughput to fast base filesystem. For modern systems with plenty of memory, fast SSD and RAID this is too limited. I recommend making this parameter configurable but for demonstration, hardcode FUSE_MAX_PAGES_PER_REQ = 256, which is 1 MB. How do you suggest to proceed?
