I'm happy to extend a warm welcome to two new members of the Percona team.

First is Yves Trudeau, about whom I can say many things:

Following the installation of memcached from apt-get and libmemcached I ran memslap for:

$ memslap -s localhost
    Threads connecting to servers 1
    Took 1.633 seconds to load data

$ memstat -s localhost
