Zimbra Zimlet WebApp

Postby mafiabusiness » Tue Sep 25, 2018 12:45 am

Hi there,

i am trying to understand why Zimbra Zimlet WebApp takes up 40GB of RAM on my installation.
Webmail is slow as syrup — yes, I have a raid-5 solution and I will change it to a RAID-10 asap — but meanwhile…

What does it do?
Why would it take up so much RAM?
(I have 98GB installed, usually after 24h of use, I have 700Mb FREE)

I have 700 users.
I have virtually no zimlets installed.
I do not use the chat.
Most users use IMAP, less than 10 on webmail.
I have Zextras installed, some clients use ActiveSync.

Many thanks for excellent forum!!

Hi Miguel,

Take a look at this documentation: https://wiki.zimbra.com/index.php?title ... eployments

I would recommend to search for "Memory Allocation" and read about mailboxd_java_heap_memory_percent and mailboxd_java_heap_size.

Best regards.
