Quick measurement of performance given various buffering size when reading/writing a file sequentially. For demo purpose.

Comment Aller Au Viet Nam

[English version here][eng].

Un petit guide de trucs de base que vous devriez savoir.

Vous devriez être capable de communiquer en anglais pour aller au Viet Nam, les gens ne parlent pas français là-bas. Certains pensent que parce que c'est une ancienne colonie française, les gens parlent français. Non, sauf quelques rares exceptions.

Préambule

Le Viet Nam est un pays en voie de développement, donc il y a plusieurs chose qui vont avoir l'air louche quant vous allez procéder à vous rendre là, ainsi que quand vous allez être là.

How To Get In Viet Nam

How To Get In Viet Nam

La [version française est ici][french].

Here I write quickly about the basics you should be aware of.

Background

Viet Nam is a developing country, so there are a lot of things that will look sketchy to you when dealing with getting there, and once you get there.

Also, if you've never been in a developing country before, you might want to read a bit about Viet Nam before getting there. There are many things you take for granted as normal behaviour that aren't necessarily something you should do there. For instance:

dskvs vs. diskv on EC2

Benchmarking dskvs against diskv on a SSD does not return usable data. For the small sized data-set (10'000 entries) on which the benchmark runs, the SSD serve diskv from its cache.

To find out the difference in performance between dskvs and diskv, I've run the same benchmark again on an EC2 t1.micro instance. Here are the results:

                           ============= dskvs ==========       =========== diskv ==========
