Cube build time increased drastically

[hankler]

Good Afternoon,
I am having an issue with a cube generation.  We've scheduled the cube update in the task manager and it has been working fine until a week ago.  The cube updated in less than 5 min, from Monday now it takes 1h 50 min approximately.  I checked the log and i noticed that "reading the data" took 1h 50 min for 67000 records, the rest of the steps were done in 1 sec.  Anybody have any idea what could be happening? The cube source is a report studio with a SQL directly to the database.

I appreciate any help.
Thanks

indexes from tables in the database were removed or got messed up?
