Hi, When I copy a large file to/from NFS mounted filesystem, the system becomes unresponsive and top command shows very high iowait(80%+) time. Though the IO operation goes through, typical throughput is < 8Mbps/sec.
On the same system, testing for Ethernet driver throughput using iperf yields close to 50Mb/sec throughput. (I am using the tip of linux-omap and running on OMAP3EVM using smc911x driver) Any pointers on what could result in degradation of throughput when using NFS and the resulting high iowait time?
