1 What about the biod daemon?

2 Like biod, nfsd self-tunes, depending on the load.

3 The biod daemon plays an important role in connectivity.

4 Further, the default number of biod daemons has now increased to 32 for each NFS V3 mount point.

5 The biod daemon improves overall NFS performance as it either empties or fills up the buffer cache, acting as a liaison of the client applications.

6 While biod self-tunes the number of threads (the daemon process creates and kills threads as needed), the maximum number of biod threads can be tuned, depending on the overall load.

7 When the server receives biod communication from the client, the server uses the nfsd daemon until the request is completed.

8 As shown in Figure 1, the biod daemon sends the requests to the server.

9 On the server, tune nfsd, which is multithreaded, like you tuned biod (other daemons you can tune include rpc.mountd and rpc.lockd).

10 The article also discusses important daemons, such as nfsd and biod, and how they actually tune themselves.

11 Then, when the client thread tries to process data within the NFS mounted file system, the data is redirected to biod, which takes the data through the LAN to the NFS Server and its nfsd daemon.
