    Default Performance and resource usage?

    Hello! We have an installation of Zimbra for a very small amount of users. However, we are looking at deploying another setup that will be hosting anywhere from 10-100+ users. I am wondering what other people out there are using for hardware. Obviously, disk space is a concern for those of us that keep every single email . But, what hardware is recommended? Is a system with 100+ users going to require TONS of RAM and a beefy dual core/cpu setup? Can a person use for example a 1.8ghz core 2 duo type system with decent ram and get good performance for 100+ users?

    Also, does zimbra support multithreading? In other words, will it take advantage of multiple CPUs/cores/threads(HT)?

    Thank you!!

    Hello, welcome to the forum.

    You should dig a bit in the forum (and blog), you'll find some data on all this.

    Zimbra and HP benchmarks showed you could get up to 50.000 users on a dual CPU server (with some RAM and fast SAN, obviously).

    I have an test/demo/friends (>50 users) servers running on a dual P3 1.2 GHz with 2 GB of RAM (and 4x36 GB HD). Obvisouly, it's slower than on a modern dual core but it runs nicely enough.

    The main parameter is the number of simultaneous users (and amount of mail sent/received).
