Characters WrittenThe number of bytes which this task has caused, or shall cause to be written to disk. Similar caveats apply here as with Characters Read.
Read SyscallsThe number of read I/O operations, i.e. syscalls like read() and pread().
Write SyscallsThe number of write I/O operations, i.e. syscalls like write() and pwrite().
Actual Bytes ReadThe number of bytes which this process really did cause to be fetched from the storage layer. Done at the submit_bio() level, so it is accurate for block-backed filesystems. This may not give sensible values for NFS and CIFS filesystems.
Actual Bytes WrittenAttempt to count the number of bytes which this process caused to be sent to the storage layer. This is done at page-dirtying time.
