If the case values happen to be in order, you can apply
binary search techinque.  This will be efficient.  For
example, the following switch block -

    switch ( caseValue )
    {
        case 12: /* ...  */
                 break;

        case  4: /* ... */
                 break;

        case 14: /* ... */
                 break;

        case 20: /* ... */
                 break;

        default: /* ... */
                 break;
    }

- can be written as -

    if ( caseValue >= 4 && caseValue <= 20 )
    {
        if ( caseValue >= 4 && caseValue <= 12 )
        {
            if ( caseValue == 4 )
            {
                /* case 4 item goes here */
            }
            else
            {
                /* case 12 item goes here */
            }
        }
        else
        {
            if ( caseValue == 14 )
            {
                /* case 14 item goes here */
            }
            else
            {
                /* case 20 item goes here */
            }
        }
    }
    else
    {
        /* default action */
    }


switch() statement was provided to avoid nested if-then-else.
So, it should be preferred instead of if-then-else, wherever
possible.

This requirement cannot be met by a few lines of code.  
Tools, like gprof(1), exist to profile the your program.
See "man gprof" for more details.
