Here's what works for me. For deeper explanation, use Google (I'm
sitting with my exams in statistics and have no time for explaining,
sorry!)
1. Buy a fast(er) harddisk
2. Compile a preempt kernel with sched_autogroup and zcache enabled.
3. Write this in /etc/rc.config
/sbin/blockdev --setra 8192 /dev/sda
echo "cfq" > /sys/block/sda/queue/scheduler
echo "32" > /sys/block/sda/queue/iosched/quantum
echo "0" > /sys/block/sda/queue/iosched/slice_idle
echo "1" > /sys/block/sda/queue/iosched/low_latency
echo "51200" > /sys/block/sda/queue/nr_requests
echo "20" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo "10" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
4. Write this in /etc/sysctl.conf:
vm.swappiness = 10
vm.vfs_cache_pressure = 50
vm.dirty_ratio = 10
vm.dirty_background_ratio = 5
5. Kick tracker, zeitgeist and similar performance-drags from your
system.
That's it. Works for me :-)
