Does anyone know the performance between zimbra 7 and 8 with same cent os 6.2? Since I got the load average of top command figures are often around 35.0 17.0 23.0, which used by email outlook client 25 users with IMAP and POP connection. All our microsoft outlook download email within local area network are very slow even timeout.
If use this same computer machine without changing any hardware configuration and also install cent os 6.2 + zimbra 7, the top load average figures around 0.78 0.65 0.55 which is much faster than zimbra 8? Is really correct? or zimbra 8 really require high hardware support.
My hardware is i5 2400 with 8G ram + 2TB hard drive x 2 - raid 1
Please help with many thanks.
