And does it influence the TTFB for Xcart4?

Actually, it doesn't affect it in v.4 either=)

Sorry for confusing you. I asked Maxim, the engineer I consulted with, why he specified the version (X-Cart 5) for our previous reply, if the answer does not depend on the X-Cart version, he said, "because the question was about that version, according to the signature". Well, some tech people love being especially precise=)

Exactly ;-)

I asked because our TTFB is actually quite high, we moved to a brand new server (VPS) which is blazingly fast and our TTFB is still quite high in my opinion.

Well, I did a couple of tests:

Though 0.2-0.3 sec (like for a static content) would probably be ideal, 0.5 and 0.6 seconds for a home and category page(dynamic ones!) seem quite good. Am I looking at a right website?

Anyway, let's avoid off-topic in this thread about Cloud Search: I asked out engineers to get in touch with you via HelpDesk, probably they will be able to suggest some improvements within website speedup and optimization services we offer.
