Is there anyone that have a idea of what kind of load handling capacity I can expect from a dedicated setup using:

* 1 Rack-Server "Compaq Proliant 1850". Dual Pentium III 2 x 500 MHz. 512 MB RAM.

Running Linux/Apache/MySql + Links SQL

I´m new to running a dedicated server, but I need to learn quick because I am going to launch a new site next year. Is the above hardware enough for a very busy site?

BTW, We also have another single-processor server lying around:

*1 Rack-Server "Compaq Proliant 1850". Single Pentium III 500 MHz. 392 MB RAM.

Can I use the above dual-pentium server standalone or in combination with the single-pentium server, or do I have to buy new servers?

Thanks in advance!
