Thanks, Eric. I should have mentioned my mod_cache settings; I already have CacheQuickHandler set to off. However I did notice in the mod_bw docs the ability to filter by MIME type as well. I specified the types of files I'm expecting to serve:
AddOutputFilterByType MOD_BW application/x-7z-compressed application/zip application/octet-stream So far, that has provided much more consistent throttling results.
