Need Statistic: How much time needs each SQL-Query

I'd like to optimize some SQL statements in my code, but which ones first? I am therefore looking for a tool for an Informix On-Line server 7.1, that makes a statistic file with each SQL statement the server executed and the time it took the server to execute it. OnCockpit can display this information including the SQL-Statement. Therefore it should be possible to obtain this informiation from the database server. Do you know a tool I could use?
