No. We suggest a minimum of 4 threads.

Internally one thread is reserved for event loop, so using a single thread would mean no spare thread for handling user requests.

HI @0x804d8000 ，Now I added LTO and Asan compilation parameters, suspected memory leak, I want to use gdb single step debugging, is there a way to make flare example sever set to 1 thread for easy debugging?

0x804d8000 commented 1 year ago

I'm afraid not. However you may consider using gdb's scheduler-locking facility to ease debugging.

I've fixed the GCC12 LTO fiber switching bug. Thx~
