I use hbrelog to switch between gathering profiles and when it does it relaunch hb. buddystore checking takes time and it seems to be cpu consuming.
I have several hb running. so switching is happen really often.
edit : I dont use buddy store product so i dont need it if that can help.
edit 2 : if someone got a way for hbrelog to not relaunch hb when it switch between profiles that can do what i want for me.
