Java Virtual Threading and Multithreading: Realistic Considerations of Concurrency Performance

The emergence of Java virtual threads has brought new possibilities to concurrent programming. Some people imagine combining virtual threads with multi-threading in parallel in order to obtain "invincible" concurrency performance. However, this idea faces realistic challenges.

The core issue lies in the compatibility of existing third-party libraries. Many third-party libraries have not been optimized for virtual threads yet. Direct mixing of virtual threads and multithreading can lead to compatibility conflicts, which can reduce system performance instead.

Although virtual threads themselves have the potential to improve concurrency performance, the maturity of the entire technology ecosystem must be considered in practical applications. Only when more third-party libraries adapt to virtual threads can we fully utilize the advantages of virtual threads and multi-thread parallelism to achieve ideal concurrency performance. Therefore, the "invincible" concurrency performance cannot be achieved by simply superimposing technology, and requires the joint efforts of the entire ecosystem.
