Very Slow to attach files.

I using Zimbra version 5 and I notice that it is very slow when attach file more than 1MB. Sometimes it will have time out connection with server error occur!

May I know what happens? Internet line or server issue ?

I have seen something similar that we traced to a browser issue, can you try the same action on a different computer and see if it still happens.

If i remember correctly, we just gave the use a new pc so we didnt get to the bottom of it but I suspect it was a corrupt firefox profile or something.

Please update your profile with the output from

Code:

---

su - zimbra
zmcontrol -v

---

as some issues may have been resolved with the latest release ;)
