DAVID MOLLITOR commented on SLF4J-458:
--------------------------------------
Woops. Thanks.
Adding more arguments will cut down on the number of arrays being created.
Updating should give customers a performance boost.
> More Multiple Argument Variants for Debug and Trace Statements

> A two argument variant is also available. For example, you can write:
> logger.debug("The new entry is {}. It replaces {}.", entry, oldEntry);
> If three or more arguments need to be passed, you can make use of the
> Object... variant of the printing methods. For example, you can write:
> logger.debug("Value {} was inserted between {} and {}.", newVal, below,
> above);
> This form incurs the hidden cost of construction of an Object[] (object
> array) which is usually very small. The one and two argument variants do not
> incur this hidden cost and exist solely for this reason (efficiency). The
> slf4j-api would be smaller/cleaner with only the Object... variant.
> {quote}
> Please create a 3 and 4 argument variant for {{debug}} and {{trace}}
> statements.
