biod daemons

• What are they?

• How do they work? in the

READ and WRITE cases?

• Why not just launch

hundreds of biods?

• Why would a client

perform better with no

biods running?

• How many biod daemons

should your client run?

• Troubleshooting

This section describes how the biod daemons work in both the read and write

scenarios. It explains why running a large number of biods does not necessarily

result in better performance. It also covers the various factors involved in selecting

the appropriate number of biod daemons to run on any given client. Finally, it

describes the tools and methods available for troubleshooting biod-related

problems.
