Thank you for your prompt response. Besides tokio, does wasmtime have any other I/O solutions? Or is there any configuration on wasmtime that can improve tokio's io performance a bit?
Thank you very much for explaining the reasons for choosing tokio in such detail. Currently, I am using [FlashDB ](https://github.com/armink/FlashDB?tab=readme-ov-file) as my database. [FlashDB ](https://github.com/armink/FlashDB?tab=readme-ov-file) has two types of file...
Hi @pchickey,thank you for your modification tips. After I made the following changes according to your tips, the performance of wasmtime has been greatly improved.   In the above...

//hi @pchickey, I'm still working on optimizing wasmtime's fd_read\fd_write performance, and I've found ```BorrowChecker``` to be a performance hotspot, at around 7% cpu. I looked at the history of commits...
Wasmtime's ```borrow checker``` should be modeled after Rust's ```borrow checker```, right? The ```borrow checker``` of Rust will only be executed by the compiler in the static code analysis phase, so...
[Issue#734]( https://github.com/bytecodealliance/wasmtime/issues/734) have some explaination of the backgroud of ```borrow checker```, the ```proposal``` mentioned in the issue is which proposal?
