Why slow to open Excel files across the network?

Good day,

There was a problem in the network, Excel files (.xls) located on a network share (Windows Server 2012R2) is extremely long in the open if they are open to anyone else. If the file is not open anywhere else - it opens immediately. The file size is very small - less than 1 MB. Clients are Windows 7 Ent x32, SP3, Office 2010, Office 2013.
In the log there are no errors. Where should I look?

Solution
What we have at the moment.
The file opens normally after re-saving. The format of the book has not changed, the file is still the same .xls. Just saved it to a new file and the old one was removed.
