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 us sy id 1 0 0 97184 2116 12844 111768 5 6 15 11 154 791 29 4 67 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 1 0 0 102620 1796 85836 43880 100 0 25 0 190 587 12 3 85 -- Adam Sampson azz@gnu.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
