I just ran a geekbench on two identical models of imac. Let's call them iMac1 and iMac2. iMac1 has a ram upgrade to 16 gbs. You would expect this to speed the machine up. Anyhow, iMac2 has a stock 8 gbs of ram. I've noticed that iMac1 doesn't boot or shut down as fast despite having more ram. I've run Onyx no it, pram, etc and after all this it's scoring some 500 points lower on the geekbench! Here's the scores: this is iMac1 with 16 gbs of ram: https://www.evernote.com/shard/s28/...5c1422e43196/81317f04141cdc5a06e96065d796442b this is iMac2 with 8: https://www.evernote.com/shard/s28/...30e28bf76349/d910eb2548949090dd7a8569b717e3f8 This is probably just crappy ram. Safe bet? I'll try it with a clean profile to see what the score is.
