The scalability work can show some wild gains in select areas. Baokun Li of Huawei has been pursuing better scalability of the EXT4 block allocation code. With Linux servers continuing to have more CPU cores and more containers being loaded on each server, Huawei began noticing scalability issues within the EXT4 file-system driver code. Profiling showed that there was significant contention within EXT4's block allocation/free code path leading to significant performance hits when running many containers atop an EXT4 file-system.
