I have a non-public question but if you can share it will be nice. What is the users size\capacity of the system? I am asking since I have seen that many squidGuard based systems have acted slower then with ICAP. By slower I mean that the initial squidGuard lookup response caused slower page display by ms to couple secs. I have not researched the exact reasons since I will not try to fix what is already fine for many.
squidGuard is slow since each process opens the database and has a private cache of 15% of the database. So if a squidGuard process does a URL lookup it does a lookup in the database cache and may read from disk (or the OS file system cache). ufdbGuard does it differently: the url_rewriter process is a lightweight process that forwards a URL lookup to a multithreaded daemon that holds a single copy of the URL database in memory. The database format is also optimised for in-memory lookups. ufdbGuard does 50,000 URL lookups/second on an Intel(R) Xeon(R) CPU E5-1620 v2 with 4 cores/8 threads.
