Hey experts can you help me with an ethernet calculation for a client server installation with ISTAR and Informix Online. If I have the following informations from tbstat -p dskreads 50 per second (Calculated worst case) bufreads 3650 per second - dskwrits 10 per second - bufwrits 100 per second - I estimate the average record length to be 80 bytes. The tables in my database will use row locking. The number of data bits to transfer between client and server will be around (3650+100)*80*8 = 2.4 Mbit per second. There will be some SQL commands, which will be transfered as well. I then suppose, that the ethernet with a capacity of 1 Mbit per second will be insuficient, but a 10 Mbit net will have the needed capacity. Is this correct ?
