Looking at my logs, the cleanupThread runs about once every 11  
minutes, and the vacuuming takes anywhere from 90s to 200s to finish.

My slon_conf_vac_frequency is set at 1, so I can't make the vacuums  
finish any faster.

Since cleanupThread runs about once per 11min, is there any way to  
get the cleanupThread to run more often?
