<p dir="auto">I'll chime in here with my own observations:</p>
<ul>
<li>The processes seem to be related to opening new emails (I get both an "about:" and some number of MTLCompilerServices)</li>
<li>The processes don't seem to spawn when opening a previously-opened email</li>
<li>W.R.T. memory consumption -- I haven't noticed whether the memory used by the processes depended on the size of the email, but I have seen MailMate's memory usage (as reported by iStat Menus) exceed 15GB -- I now periodically check, and restart the app when it gets near 10GB (I'm restarting at least daily). Currently, it's at 4.9.</li>
</ul>

When I reduce the number of “about:” processes running then I believe it should also decrease the number of MTLCompilerServices (and the amount of memory used).<br>
