Problem with speed 23800 RAR3-p (Compressed)

Where are you seeing this decrease in speed? In your own attacks or in -m 23800 -b? If it's in your own attacks, just know that there's a setting called "iterations" that, when increased, will make the hash significantly slower so the only apples-to-apples comparison is using -b because that's what onlinehashcrack used
