High CPU after 3.2.7 (in 3.2.8)

Hi there,

the high CPU issue is still happening after version 3.2.7 and regardless of the manual synchronization check value. When you check it, the async call stops for a while but then after one or two minutes, it comes back (ie: packlink_pro_controller=Async_Process). It kills your CPU to the level that our site which is not live yet was banned for a month due to the CPU consumption.
I have tried to deactivate/activate the plugin and even uninstall and install it back, but it made no difference. I also tested it weeks ago with the initial 3.2.7 and the current one 3.2.8.

Can you please look into the issue? It’s making a plugin that looks great totally unusable.

Thanks
