    Subject[FAQ?] More ram=less performance (maximum cacheable RAM)
    I've recently updated my K6-2 from 128 to 256mbytes (2x128 pc133 dimms)
    compiling kernel take now 13 minutes instead of 9 minutes :(

    Ram is so cheap and socket7 is far from the death, time for a FAQ?

    Here some description from :
    The Level2 Cache determines the board's maximum cacheable RAM.
    Boards equipped with 512k can cache up to 128MB of RAM while
    those equipped with 1MB can handle up to 256MB of RAM. If you're using all
    of the RAM cacheable by the the L2 cache, performance is enhanced. Once you
    go above the maximum cacheable RAM, performance is lost. What this means to
    you is the more cache the better. For some users, 64MB or even 128MB of RAM
    is enough, but who knows, somewhere down the road, you might want to upgrade
    to 256MB. It's nice to know your board can handle the extra memory without
    worrying about losing performance.

    More technical information can be found here :
