Enabled xcache and this happened to my memory?

    Enabled xcache the other day, does anyone have any idea how to interpret the chart below? My load average also dropped significantly, which has been nice. But I don't understand this change in Munin. It looks like my "apps" memory usage has completely disappeared after enabling xcache, and cache usage has gone up. Does this make sense?

    Often when you enable an opcache, memory usage of individual php processes goes down substantially because they don't have to include actual interpretation of code in the memory, and then the bytecode is a pooled memory space

    That wouldn't explain THIS big of a drop though
