Reproduction
I adapted and simplified reproduction from #25362 to generate ~1100 routes, all routes share the same component/page (index). I have kept the projects pretty much empty or unchanged other than that.
Nuxt 2

Nuxt 3

Build each project and test the performance of each project using ab or siege and compare the results. The projects can be built again while passing PATH_MULTIPLIER (default: 100), this way you can rebuild the projects with more or fewer routes to see how that changes the results.
Describe the bug
111 routes (PATH_MULTIPLIER=10)
- Running
siege -t 10s -c 100 "http://localhost:3000/" - Results here are comparable
| Nuxt 2 | Nuxt 3 | |
|---|---|---|
| Transactions | 13634 hits | 10573 hits |
| Availability | 100.00 % | 100.00 % |
| Elapsed time | 9.82 secs | 9.54 secs |
| Data transferred | 246.55 MB | 827.06 MB |
| Response time | 0.07 secs | 0.09 secs |
| Transaction rate | 1388.39 trans/sec | 1108.28 trans/sec |
| Throughput | 25.11 MB/sec | 86.69 MB/sec |
| Concurrency | 99.51 | 99.27 |
| Successful transactions | 13634 | 10573 |
| Failed transactions | 0 | 0 |
| Longest transaction | 0.33 | 0.43 |
| Shortest transaction | 0.01 | 0 |
1101 routes (PATH_MULTIPLIER=100)
- Running
siege -t 10s -c 100 "http://localhost:3000/" - Nuxt 2 requests took ~2x longer than previous scenario
- Nuxt 3 requests took >10x longer than previous scenario
| Nuxt 2 | Nuxt 3 | |
|---|---|---|
| Transactions | 7047 hits | 668 hits |

| Shortest transaction | 0.01 | 0.04 |
I also ran tests using ab with ab -n 1000 -c 50 http://localhost:3000/, leaving results out for legibility (and formatting is tedious).
Additional context
Users migrating from Nuxt 2 to Nuxt 3 while using the Nuxt I18n module experience memory and performance issues, due to the way routes are generated for i18n it results in the amount of routes in a project multiplied by the amount of configured languages.
Of course I will be looking into ways to improve this on the i18n module side, but as it is, the amount of routes in a project has a large impact on its performance, much more so in Nuxt 3 than in Nuxt 2.
