With Helsinki being the capital and most populous municipality of Finland, it makes for a great edge server location. Although both countries are relatively close to one another, they are separated by a distance of approximately 500km, which adds up in terms of latency. In this case, the Helsinki POP’s identifier is fihe.

Screenshot: tracing read latency for PID 181: # bpftrace -e 'kprobe:vfs_read /pid == 30153/ { @start[tid] = nsecs; } kretprobe:vfs_read /@start[tid]/ { @ns = hist(nsecs - @start[tid]); delete(@start[tid]); }'. in 2004, so I have to think back to that time to understand it. It's shaping up to be a DTrace version 2.0: I wrote seeksize.d
