Question about tablespace design

Hi all,

DB2 LUW v8 FP15

Is there any performance overhead if a table is created on data and
index tablespaces with different page sizes ?
What kind of penalty is expected ?

Sample Layout:

BufferPool A (pagesize 16K) -> Tablespace A (pagesize 16k)
BufferPool B (pagesize 8K) -> Tablespace B (pagesize 8k)

create Table a ( several fields ) in A index in B;

Thanks in advance, Michel.
