What is considered to be best practice when installing multiple instances on one physical server.

On a single instance server I have the number of tempdb drives equal to the number of processors on the box. On a four proc box I have four tempdb drives.

On a multi-instance server, with a four proc physical server, is the optimal configuration to still have four tempdb drives for each instance?

Thanks

I haven't seen the best practice change for multiple instances on a single server.

Its not TempDB Drives you Create, You split TempDB Data Files according to number of processors.I would certainly put TEMPDB in Highly read/write drives like RAID 10.
