I would guess because you are using regex acl, and each line gets compiled into a compiled regex internally to speed up the processing. A dstdomain ACL of 600K entries or 9MB uses 37MB of memory on 64-bit platforms or 23MB of memory on 32-bit platforms in my tests. Startup time for parsing this dstdomain acl was about 15-20 seconds. > Which of the redirectors/plug-ins are best for managing large blacklists if this way just won't work on this scale? The Squid dstdomain ACL is about the fastest you can find at the moment. The SquidGuard url ACL is the most flexible for more detailed matches beyond only the hostname, but overhead of using a redirector is very significant. the regex type acls is bad performers in both. Not much which can be done about that as regex have no structure. SquidGuard has one nice feature in that it can use db files to avoid building the complete index in memory on startup. And due to SquidGuard being a redirector this also saves considerably amount of memory compared to each copy of SquidGuard building it's own in-memory index.. Regards Henrik
