I.e., 21.5% slower. Which is quite a substantial gap. Here are the numbers with --enable-debug=no. OL 2.3: 22,356 auths/second OL 2.4: 17,396 auths/second So for 2.3, this is an improvement of 611 auths/second. For 2.4, this is an improvement of 1,663 auths/second. Which I find rather significant. ;)
