Can you tell us what these variables reference?
v
info

Btw, algorithmic complexity might not be the critical factor.  For
example: you seem to create a lot of single entry Hashes and then
merge them.  It would certainly be more efficient to just create a
single Hash and update that.  Or wait, I don't think you need a Hash
at all.  If all types are what I think you can probably get away with

v.attributes.each do |k|
  v.send "#{k}=", info.instance_values[k]
end

Which is much simpler and should be more efficient, too.

Kind regards
