It looks to be proportionaly with the complexity of the template that's being used.\r\n\r\nMy template (simpler version) is something like this:\r\n\r\n```mustache\r\n<h4 class=\"section-heading\">\r\n  <ALink href=\"{{activeResource}}/{{_id}}\">\r\n    {{#alias}}{{ alias }}{{else}}{{_id}}{{/}}\r\n  </ALink>\r\n</h4>\r\n\r\n{{> PCurrentState }}\r\n\r\ncreated: <strong>{{ _timestamp(created) }}</strong><br>\r\n\r\n{{! customer info }}\r\n<AMarker type=\"customer-with-booking\" />\r\n<ALink href=\"customers/{{ account }}\" title=\"{{ account }}\">\r\n  Customer:\r\n  <strong>{{#_account}}{{ .first_name }} {{ .last_name }}{{/}}\r\n    {{^_account}}{{account}}{{/}}</strong>\r\n</ALink>\r\n\r\n<br>\r\n\r\n{{! drop-off related info }}\r\n{{#dest_dropoff}}\r\n<div class=\"section-dropoff\">\r\n  <AMarker type=\"booking-agent-dropoff-confirmed\" />\r\n  Drop-off: <strong>{{ .address }}, {{ .city }}</strong>\r\n</div>\r\n{{/dest_dropoff}}\r\n\r\n{{#dest_pickup}}\r\n<div class=\"section-pickup\">\r\n  {{! pickup related info }}\r\n  <AMarker type=\"booking-agent-is-enroute-to-garage\" />\r\n  Pick-up: <strong>{{ .address }}, {{ .city }}</strong>\r\n  <br>\r\n</div>\r\n{{/dest_pickup}}\r\n```\r\n\r\nThe `.set` and render (after the set) takes about 10s. (50s) with more complex template for the same amount of item\r\n![developer_tools_-_http___localhost_5000_staging_bookings-archived_and_new_issue_ _ractivejs_ractive](https://cloud.githubusercontent.com/assets/113969/7034688/fadd9cae-dd36-11e4-9faa-06d6e51dc4ac.png)\r\n\r\nTip to speed this up?"}}
