Thanks for your reply....
I need some suggestions and clarification...
My concern is suppose to i set hardware completely... is GO will handle 80K users, (only Calender, Tasks and Fileshare.
What are entries will added in acl and acl_items table?. Because, upto i know, the most of the table will have single entries or few entries for a user, except the acl and acl_itmes, it have all the rights and other things for a user..... How many entries added in acl and acl_itmes for a single user.
eg: user have 1 share file, and 1 un shared file, 1 clander entry, and 1 task entry.
In mysql, suppose i have 80k user the acl and acl_items will have huge data.. I heard about the partition in mysql myisam engine... is it best to solve this type of problem? suggest me.
Note: I am not yet clear in the flow of code and with table structre. if you explain it, it will help for me... i search in pdf documents... it had't it.
