Most likely the NAMD load balancer fails on your side. To verify please add "ldbperiod 100000000" to your namd config and see if this stops the behavior.

> Betreff: namd-l: time per step during GPU-accelerated Implicit Solvent
> I am looking at a 200-residue protein using implicit solvent. With 4

> initially 0.01 s, but after a few 100000 steps climbs to 0.025 steps
