We’ve just pushed a new release which will resolve most of the performance issues we’ve been experiencing over the last couple of weeks.
To complete this update, we will be rebooting the database servers between 8 pm and 10 pm PST on Thursday, December 22nd (4 am-6 am GMT on Dec. 23rd). This will cause the site to be slow and potentially unresponsive for short periods while caches rebuild.
All of the servers have been upgraded and an additional caching layer (to serve content more quickly from memory, rather than having to look for it on disk) has now been implemented.
We’ve also expanded the existing caches with more machines.
Along with the performance changes, we’ve also included several small fixes, including tightening up the white space on the link lists further, selected text is once again added to the description when using the bookmarklet and other minor changes.
