... in fact if you're building, you may be better off just using a
stringbuilder and generating the delimited string. If the UniDynArray is
wrapping a string that might explain why it seems slow. (.net strings
are immutable so changing strings is a bad idea).
on the server the string manipulations are highly optimised using
various hidden pointers and hints.

actually a delimited string. Fields separated by \xFe, values by \xFD,
text encoding is 8 bit ansi so get the TextEncoding from page 1252.

UniObjects did not need a session to create a dynamic array, so you
could probably just simulate that and ignore the parenting UniSession.
