`mbw 10 -t2` results reachs >20GiB / s. However, mbw with bigger size e.g. `mbw 100 -t2` returns lower results (around 6GiB / s) => Probably `mbw 10 -t2` uses...

So I almost sure the root cause is from L3 cache + noisy neighbor problem... but if this is true, I don't come up the solution. - Other cloud platform,...

#399 try to change judge instance type from c2 to c3. At least c3 seems to be stable rather than c2 in us-east1 region.

C2D instance is interesting. It uses `EPYC 7B13` family which probably contains 112 physical cores. However, the `lscpu` of `c2d-standard-112` (maximum size) with 1 vCPU = 1 physical cores setting...

I tested a few instance types, and `c2d` and `c3` instance type seems to stabled - `c2d` - probably we can allocate a entire CCX by `c2d-highcpu-8` - It uses...

Just tried to change instance type c2d

Probably the situations was improved? Let's close it
