XLSX.write() taking too long

[irfanyounas]

Hi,
I have tried to write 3 columns and N number of rows, below we can see the time taken (on my i3 machine):

N --------------- TIME (s)
10000 --------------- 9
20000 --------------- 35
30000 --------------- 90
65000 --------------- 453

We can see that as we increase the number of rows, the time taken by the write() function increases dramatically (its not linear), its taking too long for 65000 records.
