Gziped sample xls file.

When opening big spreadsheets (xls) in Microsoft Excel 2010 (32bit software in
32bit wineprefix) from local HDD, they opens really fast, but when opening the
same files from SAMBA shares, it takes significantly more time. This problem
not related to network bandwidth. For example, 11.2 Mb. test file from
attachment opens from HDD in about 4 sec. and from SAMBA share it opens from 50
to 80 sec.. At the same time copying the same file from SAMBA share to HDD in
file manager takes about 2 sec.. Problem exists in both WINE 2.0 and
WINE-Staging 2.0. And also in both latest PlayOnLinux and CrossOver 16.1. Linux
distribution is Alt Linux P7 and Alt Linux P8 with KDE5. Version of Samba is
4.3.13.
