Sounds pretty right to me. After all it is logging information relevant to
storing objects in the cache (disk and memory). However you might want to
look at the access log. It'll tell you about hits and misses on the cache.

Read the definition of SWAPIN more carefully and you'll see it says
"The object existed on disk and was read into memory." I suspect this
means it went from the disk cache to the in-memory cache, basically the
opposite of SWAPOUT.
