I think rating/discussing the performance of the web client is somewhat subjective. I can tell you that when we first rolled out Zimbra with the web client most of our users still had IE6 and performance was pretty bad. to the point where we put our migration on hold for a while.. We upgraded everyone to IE7 and I would call the performance "acceptable". Having said that, I personally never use IE, and prefer to stick with Firefox. I think you will find that just about any of the "alternative" browsers (Firefox, Safari, Chrome) work better than IE. There were a couple of Zimbra blog posts where the speed of various browsers when using the ZWC were compared.
I agree that it might be difficult to convince a customer to switch to Firefox, but perhaps you will have some luck if you can show noticeable performance gains. |
