Hi. Here are the benchmarks for the latest Linux patch. I have noted a
sensible delay while booting: starting the INN daemon and running the
first 2-3 logins. After the first moments, all runs OK.

Also, it seems that some of the messages that are written to syslog get
mangled.

File write/copy is at the same level as 1.3.15 (that is, sensibly
worse than 1.2).
