Composer2 has been released last weekend and was announced as being much faster than previous versions. As I had some projects, where composer was pretty slow, I was curious how v2 impacts my daily work and how much of an improvement it really is. Let's say this first: It's really impressive and has already improved my work life a lot.
Curious? Let's look at numbers.
I'm working a lot in Shopware or TYPO3 projects, so these two come naturally. I'm using:
- Shopware 6.3 Production Template (6.3 branch)
- TYPO3 CMS Core Master with 5 custom extensions (v11 dev)
As my problem wasn't download speed but rather dependency resolving, I made sure to pre-warm composer caches (by basically doing all tests twice).
I did for both systems with Composer 2 and Composer 1.10:
composer install --profile --no-scripts composer update --profile --with-all-dependencies --no-scripts
--profile will display memory and timing info
--no-scripts because I'm interested in the composer performance, not in whatever scripts either Shopware or TYPO3 provide in addition
TYPO3 Composer Performance
|v1 Install||6.9s||4.85 MiB||6.51 MiB|
|v2 Install||3.92||7.97 MiB||10.5 MiB|
|v1 Update||16.19s||385.51 MiB||786.47 MiB|
|v2 Update||3.19s||27.06 MiB||138.64 MiB|
Shopware Composer Performance
|v1 Install||8s||7.56 MiB||22.02 MiB|
|v2 Install||4.5s||12.64 MiB||26.96 MiB|
|v1 Update||26.4s||439.47 MiB||1149.51 MiB|
|v2 Update||5.66s||28.99 MiB||244.27 MiB|
As you can see, especially updates are benefiting massively from the improvements - both time- and memory-wise.
Don't like numbers? Here are some pictures ;)
