-.IP " forward=<redirect|proxy>"
-When set to redirect, monetdbd tells each connecting client to make a
-new connection directly to the database the client looks for. This
-requires that the separate mserver5 processes are reachable by the ports
-they use. Since this may not be the case due to a firewall, when set to
-proxy, monetdbd tunnels the client to the right database.
-.IP " share=<yes|no|tag>"
+Most properties require the database to be stopped when set.

+.IP " nthreads=<number>"
+Defines how many worker threads the server should use to perform main
+processing. Normally, this number equals the number of available CPU
+cores in the system. Reducing this number forces the server to use less
+parallelism when executing queries, or none at all if set to
+.IR 1 .
+.IP " optpipe=<string>"
+Each server operates with a given optimiser pipeline. While the default
+usually is the best setting, for some experimental uses the pipeline can
+be changed. See the

+at all times.

+Defines if the database has to be started in readonly mode. Updates are
+rejected in this mode, and the server employs some read-only

+.IP " nclients=<number>"
+Sets the maximum amount of clients that can connect to this database at

.IP "inherit property database [database ...]"
Like set, but unsets the database-local value, and reverts to inherit
from the default again.
