Mounting NFS share increases cpu load immediately

When i mount a NFS share on my home network, the loadavg immediately increases on the client, wihtout the client or server doing any transfering of files. The loadavg decreases when i unmount the file system.

The server is configured as follows:

/etc/exports

/srv/nfs4/ 192.168.0.1/24(rw,fsid=root,no_subtree_check)
/srv/nfs4/music 192.168.0.1/24(rw,no_subtree_check,nohide)

and i use the following command when mounting:

mount -t nfs servername:/full/path/to/music /mountpoint/on/client

I have experimented with NFSv3 and NFSv4 and different options like rsize,wsize and noatime but the problem still occurs. The client and server is both running Arch Linux, but i have also tried mounting a file system on a Ubuntu server with the same results.

Troubleshooting with htop did not reveal any processes that could cause such increase in cpu load.

Do you have any ideas what could cause this problem, or where i could look for the problem?
Let me know if i need to add any information.
