Thanks Eduardo what values do you recommend ? i have 1 gb of ram and rarely use more than 20%, as it's a tor box only. should i add those values to ensure they enforce at boot in /etc/sysctl.conf ?

Show us the values of: #sysctl kern.ipc.nmbclusters kern.ipc.nmbclusters: 25600 #sysctl kern.ipc.somaxconn kern.ipc.somaxconn: 128 I put mine as example, but those values are for desktop use. Yours should be bigger (131072, 512, f.ex.), don't set an arbitrarly high value because increasing both values increase the memory needed by the kernel.
