Subj:   CPU for string operations

We are trying to find out the bad queries running on the system , for this we are using Larry Higa's ratio. i.e cputime * 1000 /diskio.

Queries that we got are using lot of string operations , such as concatenation, substring..etc.

Does the string operations or case statement cause to use more CPU?
