What the subject says, does an excessive number of ipsec tunnels slow down the firewall, does it lead to memory problems or something similar?
What would the recommended maximum number of ipsec tunnels be?
I guess it depends on the hardware since it uses resources. So the better hardware the higher the number of possible tunnels.

From experience three digit situations should be more than workable. In practice... it depends like Cedrik mentions.

The customer has 60 IPSec tunnels and reports that performance gets worse over time and recovers after a reboot.
Which version? How much IPsec traffic on average?
