Hyperthreading isn't multitasking. The effect, in an OS equipped to handle hyperthreading, is about a 30% performance improvement over a non-hyperthreading core. That it appears as two "virtual" cores is a side-effect, you don't really have eight cores.
So, four cores, four simultaneous processes.

Are you saying the x3110 only runs 2 processes at a time?
Two cores, two simultaneous processes.
These CPU's could be fine with a great deal more processes than that depending on speed requirements etc. They will just have to start time-sharing in order to run them all.

mysql_tzinfo_to_sql
MYSQL_TZINFO_TO_S(1) MySQL Database System MYSQL_TZINFO_TO_S(1)
NAME
mysql_tzinfo_to_sql - load the time zone tables
SYNOPSIS
mysql_tzinfo_to_sql arguments
DESCRIPTION
The mysql_tzinfo_to_sql program loads the time zone tables in the mysql database. It is used on systems that have a zoneinfo database (the
set of files describing time zones). Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X. One likely location for these
files is the /usr/share/zoneinfo directory (/usr/share/lib/zoneinfo on Solaris). If your system does not have a zoneinfo database, you can
use the downloadable package described in Section 10.6, "MySQL Server Time Zone Support".
mysql_tzinfo_to_sql can be invoked several ways:
shell> mysql_tzinfo_to_sql tz_dir
shell> mysql_tzinfo_to_sql tz_file tz_name
shell> mysql_tzinfo_to_sql --leap tz_file
For the first invocation syntax, pass the zoneinfo directory path name to mysql_tzinfo_to_sql and send the output into the mysql program.
For example:
shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql
mysql_tzinfo_to_sql reads your system's time zone files and generates SQL statements from them. mysql processes those statements to load
the time zone tables.
The second syntax causes mysql_tzinfo_to_sql to load a single time zone file tz_file that corresponds to a time zone name tz_name:
shell> mysql_tzinfo_to_sql tz_file tz_name | mysql -u root mysql
If your time zone needs to account for leap seconds, invoke mysql_tzinfo_to_sql using the third syntax, which initializes the leap second
information. tz_file is the name of your time zone file:
shell> mysql_tzinfo_to_sql --leap tz_file | mysql -u root mysql
After running mysql_tzinfo_to_sql, it is best to restart the server so that it does not continue to use any previously cached time zone
data.
