Optimizing CSOM updates to site collections (sharepoint online - 0365) RRS feed

  • Question

  • We are maintaining 150 school site collections via a CSOM app that synchronizes changes from other source systems.

    The process gets very slow for inserts into lists. We provide SharePoint Calendars on each site and once a year we load a years worth of new events. We have pooled connections and added code to deal with Throttling limits and this has saved some time, but it's typically 5-20 seconds per insert. (around 125 hours to process)

    Is there some way to load these in a bulk fashion?

    Would a 3rd party tool like Layer2 provide better performance?

    Should we drop OOTB SharePoint Calendars and use Outlook Group Calendars? (how do we load these? CSOM?)
