As per the https://wiki.apache.org/solr/CommitWithin

There are multiple commit strategies in Solr. The most known is explicit commits from the client. Then you have AutoCommit, configured in solrconfig.xml, which lets Solr automatically commit adds after a certain time or number of documents, and finally there may be a behind-the-scenes commit when the input buffer gets full.

You can use 'CommitWithin' to handle this problem.
Solr3.5 and later, it can be server.add(mySolrInputDocument, 10000);
In earlier versions, you can use below code
UpdateRequest req = new UpdateRequest(); req.add(mySolrInputDocument); req.setCommitWithin(10000); req.process(server);
It can reduce the frequently you send the commits.
