pos_vel

• 1000 entities with position and velocity components
• 9000 entities with position components only
• stub render system
• physics system: position += velocity

parallel

• 10000 entities with 3 simple components R, W1 and W2
• w1 system reads R and writes to W1
• w2 system reads R and writes to W2
• systems could be run in parallel
