Hello, I found an option while reading man mount_nfs: "Use sysctl(8) or modify sysctl.conf(5) to adjust the vfs.nfs.iothreads value, which is the number of kernel threads created to serve asynchronous NFS I/O requests." I tried to raise this value to a maximum of 20 and saw a decent speedup in file transfer without any visible issue.
But when using dd to write a 1GB zero file to an nfs share just for fun I saw my system become a little unresponsive while dd was running (my mouse was moving interruptedly): # dd if=/dev/zero of=/nfs_share/testfile bs=1000M count=1 How safe is it to raise this value to its maximum of 20? -- Maksim Rodin
