Hi,

I'm testing NAMD 2.7x ABF job on Ranger (TACC) and was surprised by very slow performance of ABF calculation. The production run of the same system without ABF was 0.08 days/ns, while with ABF it is 0.47 days/ns (x6 time difference!). The older version of ABF was giving no noticeable difference on the speed. Is it known issue ?
