We switched to clamd a while ago and noticed that MS uses much less RAM: 
each child had its own copy of Clam loaded into RAM with clamavmodule; 
now with clamd, only one instance is running.  It definitely is not slower!

Be aware, though, that with the external phishing signatures, clamd has 
a tendency to crash some times each day so make sure to monitor it and 
restart it as soon as it dies.  I've heard people are using monit to 
this task (
