Subject Re: High performance issues with Elastic Connector
Date Mon, 17 Sep 2018 10:55:56 GMT
Hi Gustavo,

Connector instances are pooled in general, so once a connector instance is
created it is kept around.  The number of instances will max out at the
number of connections you allow in the UI when defining the connection.
How many did you allocate?
