This is certainly my feeling too.
I am using test1-ac14, and interactivity goes straight down the tubes
when updatedb is running in the background. Switching windows in X
often takes many seconds. And simply untarring the kernel source causes
about 6 megs of application pages to be swapped out. During the untar,
applications take about 5 second to respond (e.g. to start redrawing).
It feels pretty bad...
This COULD be partially a result of shrink_mmap failing too early.
Since a lot of pages that should be reaped, are not reaped, the system
has to resort to swapping. Perhaps.
But in any case, the interactive feel is pretty bad.
