Vbscript with config and input file. Logs in Win and Ubuntu

I have installed Wine (v.1.7) on Ubuntu (v. 12.04) to run the vbscript. Libre
Office was also installed via Wine (required for vbscript). The script converts
.xls or .xlsx (input file) to .csv (output file). The problem is the following:
for the first time after installation script is running for 15 minutes (this is
longer than in Win, but it is acceptable). All subsequent times the script is
running for 1.5 hours. According to the logs, you can see that the script
processes each subsequent string in xls|xlsx longer than the previous one.
(like the loss of productivity in processing xls|xlsx)
