Data encryption at rest is a must-have for any modern Internet company. Many companies, however, don't encrypt their disks, because they fear the potential performance penalty caused by encryption overhead. Encrypting data at rest is vital for Cloudflarewith more than 200 data centres across the world. In this post, we will investigate the performance of disk encryption on Linux and explain how w

This article was discussed on Hacker News. I recently learned of csvquote, a tool that encodes troublesome CSV characters such that unix tools can correctly process them. Itreverses the encoding at the end of the pipeline, recovering the original input. The original implementation handlesCSV quotes using the straightforward, naive method. However, there’s a better approach that is not only simpl

All users of TCMalloc should consult the following documentation resources: The TCMalloc Quickstart covers downloading, installing, building, and testing TCMalloc, including incorporating within your codebase. The TCMalloc Overview covers the basic architecture of TCMalloc, and how that may affect configuration choices. The TCMalloc Reference covers the C and C++ TCMalloc API endpoints. More advan

先にまとめると ディスクI/Oに高い負荷をかけるシステムでNVMeデバイスを使うときweekly cron jobでfstrimが走る状況になってたら停止しろ じゃないとfstrimが走った瞬間にI/Oパフォーマンスが刺さって死ぬ fstrimを停止するならdiscard mount optionを有効化しろ、ただしその状態でのI/O性能で問題ないかどうか測っておけ discard mount optionを有効化しても大きいファイルの削除には気をつけろ、プチfstrimみたいになるぞ 追記されるばかりで大きくなるファイル(そして削除されるファイル)はNVMeじゃないデバイスに置いとけ 高I/Oスループットを期待するシステムでのNVMeとfstrim 社内で小さめのインスタンスを多く並べてトラフィックを捌いてたのを色々要件があって大きめのインスタンスにまとめるようなシステムアップデートをや

Expensify has an unusual technology stack in many ways. For example, we don't use DNS internally -- just configuration-managed /etc/hosts files -- and itworks great. Similarly, we only make limited use of AWS -- instead hosting our own hardware for the web and database layer -- and itworks great. But most surprising of all is that we don't use MySQL or Postgres -- instead using none other tha

Introduction Disclaimer: this post investigates how recent MKL versions behave on Zen CPUs. You should read the MKL license before using MKL. I shall not be held responsible for how you use MKL. Intel MKL has been known to use a SSE code paths on AMD CPUs that support newer SIMD instructions such as those that use the Zen microarchitecture. A (by now) well-known trick has been to set the MKL_DEBUG
