Alfresco solr.max.total.connections=40

Hello,

did anyone know why Alfresco sets solr.max.total.connections=40 in alfresco-global.properties ? I noticed that Solr starts to suffer when connections are close to 40. Is there any sort of limit or restriction related to Solr side ?

Alfresco HttpClientFactory initializes a HttpClient object from Apache commons-httpclient to invoke Solr API. Default settings confirm 40 total connections:

private int maxTotalConnections = 40;

Did anyone ever change that property ? If so, what kind of impacts are expected ?
