如何调整temporary tablespace的extent size

10.2.0.5 on windows 2008 64bit

在10g里面temporary tablespace  的extent management为local uniform size，默认为1m。

我的疑问是如何调优 temporary tablespace的extent size呢。今天阅读了一篇关于buffer busy wait的文章，说到如果buffer busy wait on temporary segment header 时，

增大' nest extent'的大小。这里可以理解为，

 A large uniform extent size
will tend to mean fewer allocations take place. Usually disk acreage for
temp is not that much of a concern, since disk SPACE is cheap and you don't
have to back up temp space.

"

这算是 extent size的一个考虑点，那还有其他的考虑点么
