Re: Slowness on local install, just with some URLs

I'm seeing the same on a two local installs of the validator.

On Ubuntu Desktop 12.10, both 64bit (my main machine) and 32 bit (a CI 
server), validation takes a long, long time (longer than a minute). On 
both machines I can retrieve the page markup with curl very quickly, 
there's no network issue. The happens when validating by direct input, 
so it's not a problem with retrieving the page markup through the validator.

On Ubuntu Server 12.04 on a remotely-hosted dedicated server I'm not 
getting the issue and the page validates just as quickly as it does at 

I tried playing around with the doctype. Only HTML5 documents validate 
quickly and this is explained by the fact that HTML5 validation is 
deferred to the validator.nu validator and hence does not use the w3c 

With doctypes that the w3c validator handles and even for simple 
documents (just an empty head and body wrapped in an html element), 
validation takes a very, very long time.

I have no idea why. But I can at least confirm that I'm seeing similar
