for high performance, all my root disk is memory,  df shows:
Filesystem           1K-blocks      Used Available Use% Mounted on
tmpfs                   800000    217932    582068  27% /

cpu was waste on sync data to /var/run/pppd2.tdb ?

Good day to you!
 
What is your disk I/O usage at this time? (at /var/run)
