一个不错blog 说明ABAP 性能:
http://blog.sina.com.cn/s/blog_5368b81a0100akh2.html
在SDN 上看到大量关于性能优化一个ST12 ,但是不在目前的系统中(ECC 6.0)
谁能知道,需要打什么pack,才能使用ST12.
最近从一个朋友从2010 tech 的文档中,看到一个STA TCODE ,听说未来会替代SE30和ST05.
STUN--分析性能的工具(Menu)
Tools -> Administration -> Monitor -> Performance 或者
Tools -> CCMS -> Control/Monitoring -> Performance menu
4.SAP 系统模块常见性能优化的BLOG&NOTE
1. ST05 - Trace requests
2. SE30 - Runtime analysis
3. SE38 -> Environment -> Perfomance examples
If you want to know all then you should start reading, tcodes will not help you.
I can offer you seven blogs:

when you read them all, and understand them, then I would maybe
send you some more unpublished one :)
Transaction code for performance tuning:
SE30 - ABAP runtime analysis
ST02 - Tune Summary.
ST03 - Workload Analysis (Tuning of buffers,.
ST03N-
ST04 - Database Performance Analysis.
ST05 - Performance Analysis (SQL Trace, etc).
ST06 - Operating System monitor.
ST06N-
ST07 - Application Monitor.
ST14 - Application Analysis.
ST02 is for Buffers
ST03 is for Performance
ST04 is for Database
SM04, SM21, SM12, SM13, ST02, ST03, ST06, ST22, ST07, DB12, DB13, DB14, OS07.
