Here is a sample of 11 proxies running Squid 1.1:

As you can see, some proxies have more reads, some have more writes. However,
on most loaded proxies, the rate of write requests is higher, often a lot
higher, than the rate of read requests.

It may be explained based on the value of document hit ratio, but there are
probably other factors. Interestingly, on NLANR cache (sv) writes (reads)
prevail only half of the day, perhaps reflecting changes in international
traffic patterns.
