Title: What is the maximum frequency for db scan?

Hello, every one.

Normally the da scan frequency is 0.1s, I want to know how to chang and what is the maximum value. For the data acquisition hardware the internal clock is very fast, from some threads it is said the vxWorks and Epics can handle 60Hz or 100Hz in maximum. Is it possible to breakthrough the limit?

Thanks for your any suggestion.
