PChome 24h 連線會慢的原因...

tl;dr:因為他們的 DNS servers 不會對 IPv6 的 AAAA record 正確的回應 NXDOMAIN,導致 DNS resolver 會不斷嘗試。 好像一行就把原因講完了啊,還是多寫一些細節好了。 起因於我的電腦連 PChome 24h 時常常會卡住,Google Chrome 會寫「Resolving host...」,於是就花了些時間找這個問題。 一開始先用幾個工具測試,發現 host 會卡,但不知道卡什麼: $ host 24h.pchome.com.tw 拿 tcpdump 出來聽的時候發現 host 會跑 A、AAAA 以及 MX 三個種類,而後面兩個都會卡住: 24h.pchome.com.tw is an alias … Continue reading

有人在 Unix & Linux Stack Exchange 上抱怨他的自動化測試在清晨會爛掉,但其他時間都好的:「Why does man print “gimme gimme gimme” at 00:30?」。 We've noticed that some of our automatic tests fail when they run at 00:30 but work fine the rest of the day. They fail with … Continue reading

RDS (MySQL/MariaDB) 支援 t2、r4 以及 m4 的新機種

這個大家等好久了,尤其 MySQL 常遇到需要用記憶體換效能的情境:「Amazon RDS for MySQL and MariaDB Supports R4, T2 and M4 Instance Types」。 先前 t2 最大只能開到 t2.large (8GB RAM),對於需要大量記憶體運算的 SQL query,就有機會被 MySQL 使用 filesort 寫到硬碟裡面暫存了。這次支援這些 instance type,開發環境至少有選擇可以開到 t2.2xlarge (32GB RAM) 跟他拼。 而 r4 應該是正式環境期待已久的 instance type 了。r3 最大是 … Continue reading
