Yes, but this isn't implemented in the plugins, it's implemented in the server. The server always uses a thread pool, but plugins can opt for more or less

...The struct can be: struct vddk_item { VixDiskLibConnectParams *params; /* connection parameters */ VixDiskLibConnection connection; /* connection */ VixDiskLibHandle handle; /* disk handle */ struct vddk_item *next; /* next handle in the list */ } struct vddk_handle { struct vddm_items *pool; pthread_mutex_t *mutex; } open() will initialize the pool of vddk_item. pread() will: - lock the mutex - take an item from the pool - unlock the mutex - perform a single request - lock the mutex - return the item to the pool - unlock the mutex Since we don't need lot of connectio...
