The overhead brings by metadata journaling is extra space and performance degrade caused frequent journal data flush. A file system based remote scheme was designed implementation. removes the I/O activities from local disk to server. According experiments in this paper, increases about 8% 19% performance, but penalty light. Although does need more CPU time for network transfer, less than 8%. And bandwidth taken 6% bound workload.
