Hi everyone,
I've searched the forum to find any solid info on performance statistics, but was unable to find anything I can relate to. I work at a university with about 30.000 students. Each student has an email account. We currently use IMP v3 (Horde v2) as a webmail server on a single server (dual Xeon based on P4, 1 GB memory). This server talks to a single IMAP server (Cyrus) (dual Xeon based on P4, 4 GB memory). The performance of this setup is awesome. The mailbox quota is currently set to 25 MB. We plan to upgrade the students webmail server this summer to a more redundant setup using Cyrus replication. The mailbox quota will probably go up to 1 GB. We're also looking at upgrading the webmail client (IMP) to something new. This might very well be the latest IMP, but I've stumbled upon Roundcube a few months ago. I tried Roundcube on my own server at home and I like it. Luckily it became stable a few weeks ago. Before considering on putting roundcube in any form of production service, I'd like to know if there are any performance figures out in the field. Current measurements show us that there are at least 500/600 active IMAP sessions at the peak moments on a single day. Will Roundcube perform in an exceptable manner with those numbers, on a single server (like we currently have)? We realize that with the increase in quota, the number of mailboxes and it's contents will increase. Will this affect the performance?
Any input is greatly appreciated.
Thnx.

I've been testing it with a single account with a folder of 13k emails (forwarded from a gmail account), and it runs considerably slower than gmail (at least showing the list of emails, or going to "next page" of emails, it can take up to 5 seconds or more).
The other folders (with about 1k emails max) are shown almost instantly, so i could guess RoundCube does not scale well with the number of emails per folder.
Please note that i've been using roundcube for only 2 days, so i may have missed something. But it's my experience nonetheless, so there you have :-) On 4/8/08, Dennis Ortsen dortsen@gmail.com wrote:

My nephew attends the University of Maine - Farmington, and he is
visiting here in the midwest this week. I glanced over his shoulder
when he used my home computer to check his e-mail, and lo and behold
I saw RoundCube in an iframe. I don't know if RC is rolled out to all
of the umaine.edu campuses, or just the one he attends. When I asked
him about the web mail system, he said it was a recent switch.
I'm not sure if the umaine.edu people frequent these lists. If not,
since you are associated with a university, they might be responsive
if you contact them directly.

That's a good tip, thanks!
I have spoken to a teacher/professor (who teaches on the IT institute of our university to see if we (IT dept.) can come up with a joint effort of putting roundcube to a test with a class of students, each with about 30 test accounts and a web test tool. He liked the idea, especially the idea that students can help to decide whether a new candidate is up to the task or not. Unfortunately the course that addresses stress test issues had just been completed when I first contacted him. He couldn't say when any next class would follow that course, but your tip might help us to find out if we can continue with roundcube. He also said that with a clear task, he might be able to contribute with a few courses to help develop roundcube. That sure is quite a motivation for the contributing students to ensure they deliver a good product.
