our network engineer says that in sql server the main reason why Disk always has IO issues (disk latency) is because the programmers write lousy code (stored procs and functions) and it causes lot of locks..

would you agree with this statement? is it balanced from your experience..

poor coding will always be a feature / source of performance issues...

to my mind the more usual reasons are poor initial database design, poor physical database design/implementation,
lack of a performance tuning stage to the development process, lack of ongoing DBA management of the databases...

... I assume that you use a peer review processing in code development?
    and that a DBA sql specialist is involved?
