If I'm not wrong IKE_SAs are stored in a linked list by default. So, the
could get worst while the number of SAs increases. Tobias told me few days
ago that one could configure charon to use a hash table instead in order to
boost the IKA_SA lookup.
Also try to log less than you would log by default. As Logging naturally
increases with the number of SAs. So , you could try to configure
strongswan.conf with logging values 0, 1 or even -1 to make it completely
Also, I'm curious by knowing how long time does your strongswan's testbed
take to establish 3000 VPN connections?
