[Qemu-devel] coroutine pool memory usage

[Peter Lieven]

Hi,

i was debugging increased memory footprint of qemu over the past time and found 
that the coroutine
pool heap usage can grow up to 70MB by just booting an Ubuntu Live CD. And 
those 70MB are never
freed.

Is this expected? Wouldn't it make sense to asynchronically throw some 
coroutines (or at least their stack)
away if there is no I/O?

Does anyone have a pointer to benchmarks of coroutine performance for NAS 
(iSCSI / NFS) with and without
freelist? I would think that it only has significant impact for local (SSD) 
storage?

Thanks,
Peter
