NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Located in alphabetical order (not prefer)

• ab – slow and single threaded, written in C
• apib – most of the features of ApacheBench (ab), also designed as a more modern replacement, written in C
• autocannon – fast HTTP/1.1 benchmarking tool written in Node.js
• baloo – Expressive end-to-end HTTP API testing made easy, written in Go (golang)

1. Download docker-compose.yml to dir named sentry
2. Change SENTRY_SECRET_KEY to random 32 char string
3. Run docker-compose up -d
4. Run docker-compose exec sentry sentry upgrade to setup database and create admin user
5. (Optional) Run docker-compose exec sentry pip install sentry-slack if you want slack plugin, it can be done later
6. Run docker-compose restart sentry
7. Sentry is now running on public port 9000

NGINX actual HTTP Request processing flow is divided into 11 stages.

The reason for this division is to perform logical subdivision request to the module as a processing unit, the various stages can contain any number of HTTP modules and pipelined manner request.

The advantage of this is to make the process more flexible, reducing the degree of coupling.

These 11 HTTP stages are as follows：

1. NGX_HTTP_POST_READ_PHASE ― The phase of the read request;

VirtualBox command-line interface (VBoxManage) provides an easy way to convert raw disk image to the VDI/VMDK format and otherwise.

Let's assume that we have raw image of the sdb device:

$ sudo dd if=/dev/sdb of=./sdb.raw

To use it with VirtualBox we need to convert it to the VDI format:

$ VBoxManage convertdd sdb.raw sdb.vdi --format VDI

The MBP is my development machine, so I needed all of my tools installed with the ability to update them with ease. In the past, I used MacPorts to take care of my MySQL, Memcached, and Ruby installions and it worked just fine. This time around however, I wanted something new and fun. Homebrew.

Homebrew is a new package manager for OS X. Unlike Fink or MacPorts, Homebrew integrates with the core operating system, reducing the number of extra libraries to install etc. Another neat feature is the ability to write software package recipes in Ruby, awesome.

Here are some raw installation instructions (clean system). I like to keep everything under user ownership to make life more enjoyable, say no to sudo.

You will need the latest version of xcode, you can get it here. After the installation is complete, you may continue.

sudo mkdir /usr/local
