<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">The biggest tweak you can do is add database scaling, so you don't hit the max-tables limit in a single database. HyperDB or MultiDB would do that - I use MultiDB on UCalgaryBlogs.ca
and it works great. Spreads the tables across several databases (16, 256 or 4096), which can hold up to "millions" of blog sites. Haven't had enough to test that claim, though. The 16 database config scales to 50,000 blogs. That should hold us for a few years.

</div>
<div>HyperDB: <a href="https://wordpress.org/plugins/hyperdb/" target="_blank">https://wordpress.org/plugins/hyperdb/</a></div>
<div><br>
</div>
<div>I started with MultiDB, back before HyperDB was a thing. If I was starting fresh, I'd go with HyperDB because it's free, maintained by Automattic, and basically what's used on WordPress.com. MultiDB woks find, but requires a subscription fee. I haven't
had the energy to migrate UCalgaryBlogs to it, because it works.</div>

<div>These are class sites and student eportfolios, so we do not ever retire or purge sites. </div>
<div><br>
</div>
<div>Students do return to old sites and take them up again even if they have been inactive for a long time, even years. </div>
<div><br>
</div>
<div>Part of our policy and what we guarantee to students is that these sites will remain available until and unless the students themselves delete them (except in the case of serious violations of our community guidelines...has not happened yet). </div>

<div>WordPress multisite works very well for this. We currently have, on our big multisite install, over 4,000 sites, with many different themes. We aren't currently using domain mapping but may soon. </div>
