Hi Taro,
The freezes are probably garbage-collection pauses. Recently (in the
snapshot builds) there is a new incremental GC mode that may improve
your program.
I have a few libraries---lux and mode-lambda---that are designed for
higher performance than 2htdp/universe and 2htdp/image but provide
similar functionalities
