Serigo,
If you have a limited amount of data you should not see response times in this range. Although, I have seen slower response time when the average transaction tables are > 2 Million records. The HANA live views are built as calculation views that, for the most part, execute in the Join Engine by design. If I build something custom using Analytic Views, the response times are often better because the processing takes place in the OLAP engine predominantly.
It would help if you could share more information about your version of HANA and HANA Hardware? Are you running true Suite on HANA or using the sidecar option with SLT to provision HANA? Which HANA Live business content are you using, etc...
