Is NEURON 5.7.159 slow compared to the previous 5.7?

Post by jtmoyer »

I installed the carbonized version of 5.7.159 and was comparing my results to the previous standard release (5.7.71, I think). I noticed that the same simulation took twice as long (43 seconds vs. 22)! Is this inherent to the version, or could it be something else? I installed 5.7.71 from the source code, could this be part of it?

That slowdown is certainly not supposed to happen. Could you
zip up all the ses/mod/hoc files needed to reproduce the problem
and send them to me so I can determine the cause of the problem.
I'll have a mac osx 4 available next Monday and can get back to
you a few days after that.

It turns out that my trouble was an artifact of the screen update interval, which replaced the Quiet button in previous versions. Setting the interval to 0.5 or 1 second (instead of 0.05) fixed the problem.
