curl::option CurlHandle,"MAXCONNECTS",10
Pass an integer as parameter. The set number will be the persistant connection cache size. The set amount will be the maximum amount of simultaneous connections that libcurl may cache between file transfers. Default is 5, and there isn't much point in changing this value unless you are perfectly aware of how this work and changes libcurl's behaviour. Note: if you have already performed transfers with this curl handle, setting a smaller MAXCONNECTS than before may cause open connections to unnecessarily get closed.
