Looking at the source for `read-xml`, it seems to be using `list->string` in several places. That is, it reads characters one-by-one and constructs a list by appending a character to the end of it, than calls `list->string` to produce the string. I suspect read-xml could be made faster by using `string-append` in these cases.
