Hmm, that tunig one db is much like tuning another is not really surprising, right. Want to know why, it's all more: memory, spindles and last cpu, it's all about separating recovery log and database (and indices). This does not mean the tsm db is anything like db2, it most likely isn't since the tsm db is not a relational database...
