This leads to more seeks on a hard drive. SSDs being much faster in doing seeks than normal hard drives may speed up a databases like gemstone a lot. Taking gemstone this is only one of the important factors. All object reads go through a shared page cache. This is the biggest performance gaining factor. If you can have a huge shared page cache where your model fits into a large extent than this will be really fast. The more your active object memory doesn't fit into the more disk performance gets important. Norbert
