Session Question

Hi, I'm working on a project. It uses large sql data to create pages. Last week I create some kind of cache info to create faster execution. It really works (system runs more than 10 times faster) But stroring cache data is problem. I use the session to store cache info. With using cache data session files growing 60K, I think it can be 100K or more. I need advice about using large session data. Or is there any way to store large array (10 or more dimestion) into memory or someting. Thanks. Sancar "Delifisek" Saran.
