Use \placefigure, \placefigure ... the correct syntax is
\placefloat[floattype][here|page|...]{}{}

\bTD 4 \clear 0/8 \eTD
I think Hans is faster to find the bug, here is a shorter example:
\starttext
\bTABLE[aligncharacter=yes,alignmentcharacter={/}]
\bTR
\bTD 4 \startcolor[red] 0/8 \stopcolor \eTD
\eTR
\eTABLE
\stoptext

Use style=mono.

Depends on your document, a few things are slower like font loading
but other things like MetaPost graphics are faster, it is also good to
have
a machine with 2 GB of memory or more .
