Initialize StringBuilder with the expected capacity (this.blank.length()) to avoid unnecessary resizing and array copying during string construction. The blank field already contains the exact length needed for the formatted output, making it an ideal initial capacity. This improves performance for correlation ID formatting, which is frequently called during logging operations. Signed-off-by: gobeomjun <[email protected]>
