How many transactions can a E4500 with 8 cpu's do?

Database transactions? Web transactions? Secure? Disk Writes? I tried to remain child-like, all I acheived was childish.

Thanks for replying jimbopalmer.
Here's the scenario. We/rather, they want to migrate out of an as400 world to UNIX and IBM has a piece of software that measures transaction, in this system, a transaction can be as simple as hiting enter, doing and update or a query. The system they are working with does about 10 trnsacion per day as an example. I've been asked how many can a sun in this case a E45 or 6500 can do.
I wish I could brek it down further but that all the info I have. If you can provide me with any info, I'll greatly appreciate it. Thanks in advacne and have a great weekend.

Just 10 transactions per day?
Performance depends on many things: number and speed of the CPUs, how the CPUs cache, how many disks the filesystems you are working in are spread across, how many controllers (if all the disks are on one controller, you are going to have a bottleneck), how fast the disks spin, if the disks are external subsystems do they have their own memory (pushing some of the data into memory rather than writing it to disk), how much memory the server has, what your kernel settings are, how the database is set up, how much memory you allow to be allocated to the database, how the program is written (if a program is poorly written, it won't perform as well), etc.
Comparing any Unix system with an AS400 is difficult. For example, the AS400 does its own disk load balancing. Unix requires the sys admin to lay out the filesystems to balance the load across the disks. You don't have the extra factor of the database application as you do in Unix.
Try going to They do benchmark testing and post their results that might help you. They do have a measure of a couple of AS400s and a Sun E4500 in their TPC-C section.
