    my actual pb is i need a expert advice in selecting the option whether go ahead with hash from a file or hash from database. Increasing the hardware or rearranging the index can be done to get a faster serach pattern. I have to do the lookup in database only , but i thought accessing databse for such inflow of records will impact performance.SO i though of option of hash from file/database. i my case 2600*100 records/min needs to be lookup and table will have 100k records i am very bad in network area.

      Even an expert cannot tell you that without knowing your system, your environment and so on. I already told you this. If you can't do the analysis yourself, you will have to hire somebody who does the analysis for you.
