CalendarServer Performance
by Gaurav Jain 28 Nov '16

Hi, * Could you please share documents of CalendarServer performance and load/stress testing? * How much memcached helps with performance of CalendarServer? For eg. I found this. 55,000 seems quite low number. - Test Scenario: With a well tuned multi-server deployment of identically configured caldav servers behind a load balancer, and a separate Postgres server with a fast RAID 0, in a low-latency lab environment using simulated iCal client load, it takes 5 or 6 caldav servers to saturate the postgres server (which becomes i/o bound at a load of about 55,000 simulated users in this test). Best Regards,

Query regarding attendee(s) inbox update.
by Gaurav Jain 25 Nov '16

25 Nov '16

Hi, I have been using DCS 7.0 for a while and it works great. But there is one issue I would like to have clarification. I assume server maintains inbox for all its principals. With that assumption, *Use case is as follows:* * Organizer A sends an invite to attendee B * Organizer A receives a success response from Server. *Now my question is:* Will the server update the inbox of B before sending the success response to A or will it be updated sometime after? *Reason I am asking:* In my case, A sends a client side notification to B to sync with server after receiving the success response. But some of the time, B is not getting the updates after syncing with server. If B syncs again after 5 - 10 secs, then it gets the update. Could you please provide some pointers? Best Regards, Gaurav Jain PS: Thank you for DCS.

Outbound email invitations
by Ian Baker 20 Nov '16

20 Nov '16

Hello, We’re using CalendarServer via macOS Server.app v5.2. Unfortunately, we’re having problems with calendar event invitations sent to external users via email. We have the com.apple.calendarserver user configured in the Calendar preferences, but when the outbound invitation mail is sent, the log reports authentication issues. There is a mismatch between the password configured for the com.apple.calendarserver system user, and that entered in the Server.app preferences. How does one modify the password for the com.apple.calendarserver system user, so that we can coordinate the two? Thanks Ian
