It gives you vague or no clue at all how much work cpu does. First you can't reliably measure cpu load on HT enabled CPU's because maximal summaric performance depends on what instructions are being executed on sibling cpus in the same time. Second what does it mean 25% for single virtual cpu? That single phisical cpu is maxed out ? What happens when two virtual cpu's have reached 25% each ? Phisical cpu is still maxed out but single virtual is slowed approximatly by half. Take this into account. To maximise cpu usage on SMP system I ended up with three servers. Fourth noticeably increased response time. 0,1 and 2,3 are siblings. Servers run with "-pingboost 1" and about 90 players connected.
