Why does Office 2010 take a long time to open an excel file with formulas?

Question

excel

Good afternoon!
there is a file with a time sheet in xls format, and here it is crammed with formulas, when you open it in the 2007 office, it takes a very long time to open, you just need to click on the cell and enter something again, everything is recalculated. I put office 2013 and open the same file - everything is ok. I return back 2007-2010, tupit. who can tell me how to overcome this?

Good afternoon!
turn off formula recalculation.
