Improving EC2 Build Speed
November 16, 2024 ยท AI Conversations
### 1. **Increase Swap Space**
EC2 free tier instances often have limited memory (RAM). Increasing the swap space can help improve performance by providing virtual memory when physical RAM is full.
– You can check your swap space by running:
free -h
– If swap space is low or unavailable, you can create a swap file:
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096 # Adjust size as needed
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon -s # To verify swap is active
– To make the swap file permanent, add it to `/etc/fstab`:
sudo nano /etc/fstab
Add this line at the end:
/swapfile none swap sw 0 0
### 2. **Use a Different EC2 Instance Type**
If your current EC2 instance is too slow, consider upgrading to a larger instance type (e.g., `t3.medium` or `t3.large`) that offers more CPU and memory. Free-tier instances (`t2.micro`) have limited resources, which could be a bottleneck.
### 3. **Enable Parallel Builds**
In some cases, the build process can be optimized by utilizing parallel processes. Check if your build tool (like Webpack or Vite) supports parallel processing:
– For Vite, you can enable parallel processing in your `vite.config.js` by setting `build.parallel`:
export default {
build: {
parallel: true,
},
};
### 4. **Use a Caching Proxy**
For npm, yarn, or other package managers, you can set up a caching proxy to avoid downloading the same dependencies every time you run `npm install`. Services like [Verdaccio](https://verdaccio.org/) or using `npm ci` with a package-lock file can speed up the installation process.
### 5. **Upgrade Disk Performance**
Free-tier instances usually have standard EBS volumes with slower I/O. You can switch to a faster EBS volume (like `gp3` instead of `gp2`) if your build process is disk-bound. You can also consider using an EC2 instance with local storage if disk speed is a critical factor.
### 6. **Use CI/CD Pipelines**
Instead of running builds on the EC2 instance, consider using CI/CD services like GitHub Actions, GitLab CI, or AWS CodePipeline, which often have more powerful environments for handling builds. This can offload the build process from your EC2 instance and speed up the development cycle.
### 7. **Optimize Node.js and npm/yarn Configuration**
– Ensure you're using the latest stable versions of Node.js and npm/yarn.
– Consider using `npm ci` instead of `npm install` to speed up the install process, especially in production environments.
– Run `npm audit fix` periodically to ensure your dependencies are up-to-date and free from unnecessary security packages.
### 8. **Optimize Your Codebase**
If you have a large codebase, consider breaking down large modules and optimizing dependencies. Look into tree shaking, reducing the number of packages, or lazy loading.
