I'd venture to say that's an issue with your personal system. I regularly stomp 100+ files with no problem. How much ram do you have?
Indeed it is, I understand the problem now. Blogstomp is bulk compressing high res files, so it does depend upon your system spec. I've got 8GB of RAM, i7-2630QM @ 2.00GHz, NVIDIA 2.0GB, 750GB (forget the type, but regular, non SSD), Win7 (that might be useful for anyone else looking). It manages around 60-80 high res (25MP) files, so I just did it in sections.
I've had a play now, seems quite good. I think I like it.
