Oracle Performance on CMT based servers 芯片多线程服务器上的Oracle性能

Oracle Performance on CMT(Chip Multi-threading) based servers
芯片多线程(CMT)服务器之上的Oracle性能

参考资料
Oracle Performance on Sunfire T2000
SunFire T2000 servers are best suited for Oracle MiddleTier
Oracle running on CMT
Migration from UltraSPARC I,-V to UltraSPARC T1 and T2 results in 2/3 performance reduction

文章指出:
T2000拥有8核4线程(Chip-level MultiThreading), 很强大
因为是CMT架构的, 适用于大量并行并发的操作
但每个单线程性能相对较差, 不适用于单线程的空间密集(?)的CPU操作(The T2000 architecture is not suitable for single threaded spatial intense CPU operations)
对于Oracle一些操作来说, 得启用并行(parallel)功能, 才能发挥出最大性能.
