It probably is "good enough" in practice. There may be some issues following the fix of some memory leaks in Instant earlier this year. Garth > It would be very welcome if you had a look at it.

Status in DOLFIN: New Bug description: In my Python Code I need to evaluate a nonlinear functional many times. This was rather slow and after a profile run, I've noticed that 90% of the time was spent in the __init__ routine of form.py to compile the form. As far as I can survey the code, this should be necessary only once. I have attached a simple example that illustrates the effect. In my test, the second code is roughly 40 times faster. _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : dolfin@lists.launchpad.net Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
