My MC jobs that I run locally at IU have gone from 5 minutes to run to 10 hours when using software version "version_4.0.0". I'm running geant3. Has anyone else tried working with this build yet?
Possibly also related: during the geant step I get many warning messages of the form: "Warning in savehits: unsaved hit information found from sensitive volume XXXX, hit discarded". These blow up my logfiles to ~hundreds of megabytes.
I tried running with version_3.8 and version_3.9 too. These ran fast and didn't produce the same warning messages.
I experience this both with a photon gun and an omega->3pi simulation.
