Under load, this creates GC pressure that can devastate throughput. The JavaScript engine spends significant time collecting short-lived objects instead of doing useful work. Latency becomes unpredictable as GC pauses interrupt request handling. I've seen SSR workloads where garbage collection accounts for a substantial portion (up to and beyond 50%) of total CPU time per request. That's time that could be spent actually rendering content.

The irony is that streaming SSR is supposed to improve performance by sending content incrementally. But the overhead of the streams machinery can negate those gains, especially for pages with many small components. Developers sometimes find that buffering the entire response is actually faster than streaming through Web streams — defeating the purpose entirely.
