Compiling the presentation I‘m talking about for the first time on my laptop takes about 210 seconds. Every subsequent compilation takes about 70 seconds. I know my laptop is old and slow. But if I make a copy of the presentation source and remove the \typesetbuffer commands, first compilation takes about 22 seconds and subsequent compilations take about 7 seconds. I have no idea on how ConTeXt works internally, but what I’m trying to say is that if \typesetbuffer has been already compiled, compiling again is no gain. >> 3.

My second suggestion isn’t about compilation time, but about duplicated fonts. I tried to provide a sample, but I don’t know why it doesn’t work: \starttext These are bufers: \dorecurse{10}{\startbuffer[text:\recurselevel]\setuppapersize[A7]\starttext\input tufte\stoptext\stopbuffer\typesetbuffer[text:\recurselevel][frame=on]} \stoptext Of course, fonts are embedded fine in documents, but \typesetbuffer is a special case. Having the fonts embedded only once in the final document would be better.
