Ivan Zhakov commented on SERF-173:
----------------------------------
Subversion doesn't into this issue because it opens connections slowly
one-by-one. See libsvn_ra_serf/update.c:open_connection_if_needed():
{noformat}
/** Minimum nr. of outstanding requests needed before a new connection is
* opened. */
#define REQS_PER_CONN 8
/** This function creates a new connection for this serf session, but only
* if the number of NUM_ACTIVE_REQS > REQS_PER_CONN or if there currently is
* only one main connection open.
*/
static svn_error_t *
open_connection_if_needed(svn_ra_serf__session_t *sess, int num_active_reqs)
{
/* For each REQS_PER_CONN outstanding requests open a new connection, with
* a minimum of 1 extra connection. */
if (sess->num_conns == 1 ||
((num_active_reqs / REQS_PER_CONN) > sess->num_conns))
{
int cur = sess->num_conns;
apr_status_t status;
sess->conns[cur] = apr_pcalloc(sess->pool, sizeof(*sess->conns[cur]));

NULL, NULL);

sess->conns[cur],
