Hi, First of all thanks for alembic which is great asset to have in your development toolbelt.
I am experiencing large slowdowns when generating offline or doing online migrations or even generating history. One of the CPU cores stays at 100% for a large number of seconds. I have 141 migrations 32 branchpoints and 40 merges The hardware is: Intel® Core™ i7-4510U CPU @ 2.00GHz × 4 with 8 GB of RAM Each time I do a merge the time seems to grows. It looks to me that alembic spends a lot of time calculating some dependency tree. Some timings on commands *minutes:seconds*: alembic history 1:31.57 total alembic downgrade head:325b273d61bd --sql 1:24.10 total // This just targets one migration Is this a known problem? Any way I can speed it up? Thanks, Pawel -- You received this message because you are subscribed to the Google Groups "sqlalchemy-alembic" group.
