Offload inbox updates to a queue handler to speed up posting online Moved much of the writing that happens when posting a notice to a new queuehandler, distribqueuehandler. This updates tags, groups, replies and inboxes at queue time (or at Web time, if queues are disabled). To make this work well, I had to break up the monolithic Notice::blowCaches() and make cache blowing happen closer to where data is updated.

Offload inbox updates to a queue handler to speed up posting online Moved much of the writing that happens when posting a notice to a new queuehandler, distribqueuehandler. This updates tags, groups, replies and inboxes at queue time (or at Web time, if queues are disabled). To make this work well, I had to break up the monolithic Notice::blowCaches() and make cache blowing happen closer to where data is updated.

Offload inbox updates to a queue handler to speed up posting online Moved much of the writing that happens when posting a notice to a new queuehandler, distribqueuehandler. This updates tags, groups, replies and inboxes at queue time (or at Web time, if queues are disabled). To make this work well, I had to break up the monolithic Notice::blowCaches() and make cache blowing happen closer to where data is updated.
