Re: [Libguestfs] libnbd flamegraph Odd benchmark results

That might be the reason I have 8GB(7.7) of ram I verify 7.4 available by running in tty only mode and it gets filled pretty quickly (vmstat) Strange thing is that this also happens at size=1G. Command I am running is sudo perf record -a -g --call-graph=dwarf -F 300 ./sparse-random-test.sh ``` libnbd/profiling/sparse-random-test.sh ../../nbdkit/nbdkit -U - sparse-random size=16G --run "MALLOC_CHECK_= ../run nbdcopy \$uri \$uri" ``` -F doesn't affect the result much, it decreases the sampling rate to avoid CPU/IO overload caused by perf. On a related note, what should I fill as server requirements in the OSU open source lab application asking for a test server? I was thinking that a dedicated server unit with 16-32GB, 1TB should be enough. Regards, Abhay
