Hi.
Loading a large plain data file takes very long.
This problem was described at:
http://wiki.services.openoffice.org/wiki/Calc/Performance/The_Ou_case

Look at file:
http://svn.services.openoffice.org/opengrok/xref/DEV300_m94/sc/source/filter/xml/xmlsubti.cxx

38% of time spent in ScMyTables::NewColumn() because of replicated use of 
aTableVec[nTableCount - 1] (vector::operator[]) 

What do you think about instead using:
    aTableVec[nTableCount - 1]
use instead:
    aTableVec.back()

I think it could increase an perfomance slightly.

Best Regards
Bartisz
