many http requests for /purge/tag/, slow response times

[bozzmedia]

After logging our http requests I noticed many urls containing /purge/tag or /purge/author/ with 2-4 second response times. Our page edits are slow to save and wondering if this may be part of the issue.

Example:

https://redacted.org/purge/tag/roger-redacted/feed/rdf/
	200 	0.8553 	23 hours
https://redacted.org/purge/tag/roger-redacted/feed/atom/
	200 	0.9721 	23 hours
https://redacted.org/purge/tag/roger-redacted/feed/
	200 	0.8625 	23 hours
https://redacted.org/purge/tag/roger-redacted
	200 	2.2739 	23 hours

I am trying to interpret Could this indicate an issue with enabling the auto purge on post updates? Is that a typical response time? Appreciate any insights, thanks!

Seems similar to #257

I would suggest this fix. But the repository seems private, I can't commit.
In my test case it speeds up Wordpress post saving from 9 seconds to 2 seconds.
