exFAT Achieves Better Sequential Read Performance With Linux 7.0
The open-source Linux file-system driver for supporting Microsoft's exFAT now can deliver better sequential read performance with Linux 7.0 thanks to multi-cluster support.
The work previously covered back in December for exFAT on Linux using multi-cluster support and Upcoming exFAT Linux Driver Patch Can Boost Sequential Read Performance By ~10% has been merged for Linux 7.0. This can improve performance by about 10% while also having lower overhead. This multi-cluster/contiguous cluster support can deliver better sequential read performance especially when using small cluster sizes. The 10% improvement is with a 512 byte cluster size.
The exFAT code for Linux 7.0 also optimized consecutive FAT entry reads by caching buffer heads to significantly reduce sb_bread() calls. The exFAT code for Linux 7.0 also improved error code handling and other improvements.
