It seems that the new beta is using less memory than the old version. In 7.3 with 512 MB of Ram I am sitting around 69% fairly consistently. In 7.4 with 1024 MB of Ram I am sitting at 21%. Assuming 7.4 would use 42% if it only had 512 MB so that it a nice improvement to the memory management.
After 12 days of use memory use is sitting at 71%. I did a restart on the box and with my services configuration I am sitting at 61% after the reboot. I plan to do a longer test and see if it continues to slowly rise or if it stops.
as long as you aren't using more than 10% of swap you are Fine. The memory usage display show application usage only..not how much is being used in cache..otherwise it would read 90-95% at all times.
