are you marking ruby instances yourself ?

can you estimate roughly how many ruby-instances you have ?
A: 0     < n < 500
B: 500   < n < 5000
C: 5000  < n < 50000
D: 50000 < n < infinite


perhaps you are having a thread which is consuming all time ?
maybe pause all threads during GC can help (untested).
  rb_thread_stop_timer();
  rb_gc_start();
  rb_thread_start_timer();
