QStringList optimize code block

[pdoria]

Hi guys,

Given two CSV strings (ptag and pdata)...
Want to join them in a single QStringList...

Can the following code block be optimized?

QString ptag = query.value(0).toString();
        QString pdata = query.value(1).toString();
 
        QStringList tag = ptag.split(",");
        QStringList data = pdata.split(",");
 
        for (int n=0; n < tag.size(); n++)
            this->protocols << tag.at(n) + data.at(n);

QString ptag = query.value(0).toString();
        QString pdata = query.value(1).toString();

        QStringList tag = ptag.split(",");
        QStringList data = pdata.split(",");

        for (int n=0; n < tag.size(); n++)
            this->protocols << tag.at(n) + data.at(n);

To copy to clipboard, switch view to plain text mode 

Thx in advance!

++n is faster than n++, but the compiler will normally optimize that. Also

int size = tag.size();
for (int n = 0; n < size; ++n)

int size = tag.size();
for (int n = 0; n < size; ++n)

could help. Have you compared the speed of at() and []? Further I do not see any possibilities to speed up that code.
