how long needs a pig query

[Marko Bauhardt]

hi all,
we ran into performance problems by executing several pig-queries. so  
in our case it is important to see how long needs a pig query.
is it possible to see in the logfiles how long needs a pig query to  
execute? if no is the class "POMapreduce" in method "open()"
at "pigServer.store(dbTable.getAlias(), storeFile.toString(),  
storeStatement);"
the correct place to make a debug statement.
e.g.

        long startTime = System.currentTimeMillis();

        boolean success = mapReduceLauncher.launchPig(this);

        long endTime = System.currentTimeMillis();
        long diff = (endTime - startTime) / 1000;
        log.info("launched pig in " + diff + " sec.");


thanks for hints
