Hi Guys, This progress report includes very important benchmarking results, which shows i) Write will always improve - It boosts writes (396% in the best case) even with really small cache (say, 64MB) because of the sophisticated writeback optimization. ii) Read won't be bad - It doesn't so much deteriorate the read (less than 1% for SSD+HDD case) because of the insignificant overhead. iii) Good in application workloads - 22% improvement with read-intensive workload and 234-299% improvement with fileserver workload (using dbench) Yeah, merging Writeboost into the mainline is my goal now and I really need your feedbacks. For more details, please read the previous post. Cheers, - Akira -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
