 * Hi, thanks for making such improvements for WP available.
   I’m interested to know
   how this works on Multisite, since the Users table is shared across all sites.
   If there are multiple networks, must it be enabled for each network, or just 
   the main one? And is the scheduled task being run for every site, or just the
   primary site?

 * Thanks for the question.
 * Yes, this works on multisite, handling the user tables correctly. The way it’s
   set up, each site needs to add its own high-performance keys. That can be done
   from within Tools->Index MySQL on each subsite, or with wp-cli. Edmund Turbin
   published a shell script to do it, which you might find helpful. [https://github.com/spicecadet/index-mysql-multisite-enable](https://github.com/spicecadet/index-mysql-multisite-enable)
 * I don’t understand what you mean by “multiple networks”. I guess you mean “multiple
   sites within the single multisite installation (a/k/a network installation).”
 * There’s no scheduled task in this plugin.

 * Hi Ollie, thanks for your response.
   I made a mistake, apologies for the confusion–
   the question was intended for the Index Users plugin. I’ll report there for the
   sake of clarity.Thanks though for the Edmund Turbin link – I’m taking a look 
   now.Multiple networks is many networks, each with many sites, all on a single
   installation – so it’s possible to Network Enable a plugin on one network of 
   sites, without it being enabled on sites on other networks. But since the User
   table is shared across all sites on all networks, I’d imagine that enabling it
   on one network, would effectively apply to all.
