Mmm, that is weird. Something odd is going on, I'm curious. At least O1 should be way faster than O2. Are you up-to-date? Will look into it, and will get back to you soon.

Thanks!

Thanks Fabio,

"parameters["coffee"] = {}" makes a huge difference, compiles in 1 min. Using O1 is almost as slow as O2 (~13 min).

Hello Tuomas!

For disabling coffee adding "parameters["coffee"] = {}" at the top of your file should do the trick.

You could retain some caffeine while decreasing code generation time by instead setting "parameters["coffee"] = {'O1'=True}" (note: default is O2=True, which is more aggressive - as expected - than O1)

Hello Firedrakers,

I'm using "fd_bendy" branches of FFC and UFL, and it takes ~15 min to
compile the attached example (with master branches it takes only ~1
min). Is there any way to speed it up? Are there some optimization flags
I can turn off? I'm running small test cases so runtime efficiency is
not a concern.

Cheers,

Tuomas
