Limited by fuse in kernel, the read size of read request from fuse is not greater than 128KB so that fuse client only reads a little part of objExtent in each read request. So read shows low performance.
In this pr, read ahead can be choosen to applied by add config ' "enableReadAhead": true ' and make read show high performance in sequential read.
