[Engine-devel] AsyncTaskManager and the irsbroker
hi, I have just noticed that AsyncTaskManager is - almost all of the public methods are synchronized - and it is singleton - calling to VDS operations (line 291) Therefore this may be a performance bottleneck. Even when you want to create an asynchronous task or query a task's state, you may have to wait till a remote vdsm responds. Would it be ok to remove the synchronization from e.g. the query-like methods? Or the one initiating remote calls? Laszlo
Hi Laszlo, Sorry for the very late response, You are correct. We have inefficient synchronization issues. For example - I wonder whether we should have AsyncTaskManager instance per data center Yair ----- Original Message -----
