With the > 2189, that value is almost half at around 230 MB/s. since a normal disk can maybe do 80Mbyte/sec on a sunny day while going downhill.. it looks like your benchmark is measuring something else (like VM caching policy).... if you want to measure disk throughput you might want to consider using another benchmark; I tend to use tiobench (tiobench.sf.net) for things like this... -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
