Hi guys. I have a server with this configuration: Intel xeon E5-2670 with 8 cores, 2.60GHz (3.30 GHz with Turbo Boost), 20MB of cache, QPI Link 8GT/s; Hyper-threading, 1600MHz TDP of 115 Watts; 32GB ( 4 x 8GB ) RAM DDR3-1333MHz, Dual rank x4; RAID 5; 3 HDs SAS 6Gbps of 300GB, 10k RPM, Hot Plug; CacheCade 200GB SSD SAS Is this enough to support 7000 simultaneous users? For 15000 users is enough? Whats the better configuration of squid with a server like this? Whats value I can use in cache_mem? In cache_dir option, is advisable to use diskd or aufs? And the other options: cache_swap_low ?? cache_swap_high ?? cache_replacement_policy ?? memory_replacement_policy ?? I'd like a configuration for maximum performance. Someone can help me? Regards, MSC
