We always use this configuration on our small vps i.e. 4cpu, 16gb ram,
recently we started caping iops & io to 2048, 8mb/s respectively (we're yet to see how it goes), we were not caping those before but the following config we are using throughout the year i guess, of course also we constantly tune database thanks to releem.. P.S. nproc we set to 150 on every package because we found unsual queuing chocking the server with 1024, 8mb/s iops and io while nproc was 50 first and even after set to 100...
cPFence any suggestions?
