Probably not from one table, but if you start adding table lookups for other things you could push the working program size over the limit to be kept in the cache. I've not really looked into why the speed improvements I saw on my Celeron didn't make any difference on the PII, but the cache size/speed would be my first guess. The fact that my Celeron cache runs at full speed compared to the half speed PII cache means there's a nice boost when it does keep within it, and it still averages out at about PII speed even when it doesn't! It'll probably be worth looking into at some point to see if it help much... Si
