Edit: Or was I just imagining things? I tried the test from the"Filesystem caches are more important than other caches" section of the article here:

My results:
Code: Select all
# sync
# echo 3 > /proc/sys/vm/drop_caches
# dd if=/dev/zero of=/tmp/testfile count=1 bs=900M
1+0 records in
1+0 records out

# sysctl -w vm.vfs_cache_pressure=100
vm.vfs_cache_pressure = 100
# find / > /dev/null
# cp /tmp/testfile /tmp/testfile2
# time find / > /dev/null
real 0m2.873s
user 0m0.844s
sys 0m1.488s
# sysctl -w vm.vfs_cache_pressure=50
vm.vfs_cache_pressure = 50
# find / > /dev/null
# cp /tmp/testfile2 /tmp/testfile3
# time find / > /dev/null
real 0m3.264s
user 0m0.880s
sys 0m1.504sSo, the second run didn't take any less time, looks like.
