More speed =)

Hey!
Is it possible to increase the speed of the following when:
with segyio.open(files, mode='r', ignore_geometry=True) as sgy:
RP = sgy.attributes(147)[:]
I have about 2 million traces and this procedure takes a very long time.
And one more question.
Is it also possible to increase the performance of this code:
with segyio.open(files, mode='r+', ignore_geometry=True, strict = False) as sgy:
for x in sgy.header[:]:
x.update({69: 10, 71: 10 })
Thanks!

Hi,
attributes
is designed to be the faster faster option in this case, compared to header
.
Your second example looks ok too. How slow are we talking here? Do you have any measurement for the two scripts?

Error in another.

It's stupid not to think about it.
