Hm, with 4 cores and a ratio of 4, there is only one bucket per
listener, which is the same as the default.
Did you try the same test without the directive or with a ratio of 0?
(I rather suspect a connectivity issue with ab)

i did not test it much and honestly i am not able to make a decision based on http://httpd.apache.org/docs/2.4/mod/mpm_common.html#listencoresbucketsratio

without the directive all is unchanged and stable

0 is not accepted which i would consider a bug given
the docs days default  "ListenCoresBucketsRatio 0 (disabled)"
AH00526: Syntax error on line 48 of /etc/httpd/conf/httpd-core.conf:

i just wanted to test the new feature on a 4.2.3 kernel

"ab" don't scale well but likely not a connectivity issue runnig it on the same machine like httpd
