Reply to E2E post are extremely slow.

After E2E update, I find it is extremely slow (usually takes more than 10 seconds) after I press "Reply" button to any E2E post until the reply is finished. I connect from Taipei, Taiwan with high speed fiber connection so it won't be network issue. Can you help to check why there is such such latency? By the way, I see E2E side is under maintenance for hours in the past 12 hours and I would suggest you to make an announcement to E2E user before you do maintenance.
