Hi Ganesh, I'm not an expert on pysolr, but from a quick scan of their update code, it does look like pysolr attempts to send update requests to _a_ leader node for a particular collection. But that's all it does. It doesn't check which shard the document(s) will belong to and try to pick the _correct_ leader. If your collections only have 1 shard, this is still pretty great. But if your collections have multiple shards (and multiple leaders), then this will perform worse than SolrJ.
(This is based on what I gleaned from the code here: https://github.com/django-haystack/pysolr/blob/master/pysolr.py#L1268 . Happy to be corrected by someone with more context.)
