whats your memory like when using handbrake? for a long time i've been using the purge command to clear the inactive memory back to 'free'. i wanted to know - am i supposed to do this? is handbrake supposed to turn all of my 16 gigabytes of ram into 'inactive' memory?? before i owned an SSD my mac would get very sluggish, almost unusable when it would page out and swap, so ever since then i always purge or restart if my system has been swapping (say overnight handbrake). is there a way around this to stop this inactive memory build up?? second question is about CPU usage - i've heard theres a way to 'throttle' it down - does anyone know how to do that? and can they tell me what their experience with is like? does it make handbrake less stable, or perform significantly slower? has it ever caused corruption or failed encodes? i hope someone will reply, thanks for replying in advance.
