The VM balancing updates in the recent ac kernels seem to have caused
some interesting performance problems on my desktop machine. I've got
160Mb of RAM, and 2.4.2-ac1 appears to be using excessively large
amounts of it for buffers and cache while pushing stuff out to
swap. This means that Mozilla, for instance, runs significantly worse
than under 2.4.0, since bits of it are being swapped in and out.
After the machine had been sitting for a while not doing very much:
procs memory swap io system
cpu
r b w swpd free buff cache si so bi bo in cs

After some heavy reiserfs disk IO (deleting lots of small files):
procs memory swap io system
cpu
r b w swpd free buff cache si so bi bo in cs
us sy id
