Runs up to 20 times faster than conventional VBA code. qUtopic.xll™ has been coded in fully portable C++ that makes it very light and extremely fast.
Excel interprets VBA code in real time every time it runs. An XLL is an add-in precompiled in a language with a very modest overhead. Only the libraries used are included.
Excel does not consider an XLL a macro, so it doesn’t require the user to change settings or give approval every time is used.
XLL technology has been available for decades with a prominent use in trading floors with strong quantitative requirements.
