You have either a very slow server or a very bad bcrypt implementation. Running bcrypt in python on my 5 year old server has these results:

>>> timeit.timeit("bcrypt.hashpw('this is a password', bcrypt.gensalt(11))", setup="import bcrypt", number=5) / 5

0.13497538566589357

>>> timeit.timeit("bcrypt.hashpw('this is a password', bcrypt.gensalt(12))", setup="import bcrypt", number=5) / 5

0.28287739753723146

>>> timeit.timeit("bcrypt.hashpw('this is a password', bcrypt.gensalt(13))", setup="import bcrypt", number=5) / 5

0.5341608047485351

>>> timeit.timeit("bcrypt.hashpw('this is a password', bcrypt.gensalt(14))", setup="import bcrypt", number=5) / 5

1.069920015335083

>>> timeit.timeit("bcrypt.hashpw('this is a password', bcrypt.gensalt(15))", setup="import bcrypt", number=5) / 5

2.151028203964233

That's five repetitions of a bcrypt hash with the work factor passed in bcrypt.gensalt(). The resulting units are seconds.
