Hey, I was reading some tuning guides and came across Krystian's blog post http://kly.no/posts/2010_01_26__Varnish_best_practices__.html which notes the following:
On Linux, -sfile performs far better than -smalloc once you start hitting disk Assuming we have a dataset that we know is going to be larger than RAM, can I confirm, even with non-SSD's that Varnish is more performant with -sfile over -smalloc b/c swap is going to be slower than mmap() against a file ? What happens if the dataset is larger than the file ? We are looking to host multiple sites through our varnish cluster which is certainly not going to all fit into RAM so we want to choose the right option here and we dont have an SSD option. Thanks _AD
