- 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 ?
-
- Thanks for your help from
