We're getting similar figures, but it isn't in the restart time that
you take the hit. Our cache (Digital Alpha, 512Mb RAM, 8Gb cache
disk; typically 1Gb/day traffic) takes an immediate dive on hit rate
after restarting. We typically see the hit rate fall from around 22%
of bytes to 13% for the day after the restart.

Since we're paying per megabyte, each restart costs us typically
around $70 in lost cache hits. Daily reboots are not an option :-).
