Browsers actually validate the certificate through CRL &#x2F; OCSP for EV sites, if I recall correctly.<p>That takes time and adds latency and there are differences between CA&#x27;s in OCSP server performance. Your location can obviously impact performance too. If you&#x27;re performance conscious you might want to take this into account.<p>This is actually something people don&#x27;t consider when they say certificates should be free - running these CRL &#x2F; OCSP servers costs money.<p><a href="https:&#x2F;&#x2F;www.imperialviolet.org&#x2F;2012&#x2F;02&#x2F;05&#x2F;crlsets.html" rel="nofollow">https:&#x2F;&#x2F;www.imperialviolet.org&#x2F;2012&#x2F;02&#x2F;05&#x2F;crlsets.html</a><p>Netcraft does OCSP responder performance analytics: <a href="http:&#x2F;&#x2F;uptime.netcraft.com&#x2F;perf&#x2F;reports&#x2F;performance&#x2F;OCSP" rel="nofollow">http:&#x2F;&#x2F;uptime.netcraft.com&#x2F;perf&#x2F;reports&#x2F;performance&#x2F;OCSP</a>
