Re: Interactive performance regression since 2.0

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    Please try this patch, Hasso.  This is not a complete solution but
    it should help. 

fetch http://apollo.backplane.com/DFlyMisc/sched01.patch

    It muffs up some of the optimizations I made for the network stack and
    depends way to heavily on the scheduler helper thread.  I
    need to make some significant changes to the way the scheduler
    tracks the current process and create a generic priority field that
    can be propogated in messages to clean those up.

    Note that firefox screws up interactive performance even under the best
    of circumstances.  Half the sites I bring up cause it to spam the X
    server at 100% for seconds on end for reasons beyond my understanding.

    In anycase, if this patch works ok for you I will commit it as a
    temporary bandaid while I work on something better.
