Upgrading from 1.0.4 to latest version (or just 1.0.5) slows down migrations by ~factor 19

[fkoehler]

We have about 20 migrations. We run them in v1.0.4 in about 2s against a local single node C*.
When I upgrade to 1.0.5 (or latest stable 2.1.1) this goes up to 38s.

Is there a good reason for that? I can not see one looking the changes from 1.0.4 to 1.0.5. I am also worried because nobody else seems to have this issue?

Sounds weird. Maybe the cassandra driver update is causing this (you could change the dependency in plugins.sbt to verify this)?

[fkoehler]

That's my guess as well. I could not find anything in the change log in regards to that.
I will try to downgrade the driver

You could take a thread dump, perhaps that provides some insights.

While this is reported for a multi node setup it sounds similar and the linked issue might affect a single node as well, not sure - http://stackoverflow.com/questions/38884442/how-to-speeden-up-schema-agreement-in-cassandra
