Hi,
I am using the memslap client tool from Memcached-libmemcached-4406
package. In my tests I observed that if I put get/set ratio 1:0 i.e
100% GETs then the tool reports incorrect TPS numbers at the end of
the test. It actually is considering the SET numbers also but the time
calculated is only for the GETs. See the below output. The test ran
for more than 100s as the tool has to do initial SETs. We should
ideally do not consider the SET numbers and concentrate only on GETs
as this test is a 100% GET.
