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. -BenRI -- "I want to be in the light, as He is in the Light, I want to shine like the stars in the heavens." - DC Talk, "In the Light" Benjamin Redelings I <>< http://www.bol.ucla.edu/~bredelin/ -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
