ACLs limts/perfs ?

We're currently wanting to implement spamhaus "drop" and "edrop" lists
so that we can deny access to those bad networks.

In order to do so, we've created a small script that downloads those
lists, parse them and create an ACL, in for form:
acl spamhaus {

After the whole process is finished the ACL holds more than 800 entries.

Will it be an issue for a high-traffic application? Will varnish have
some performance issues with such a long list?

If so, what do you propose as alternative? Multiple ACL blocks?

Thank you in advance for your help.
