I'm hosting all my websites through Tilaa, as of end ****. I manage 2 VPS'es, they are performing blazing fast without any problems.
One of the sites serves easily 200 unique visits per second with a server load of *.**.
The support is great, quick and personal. No 9-to-5 mentality, but also reachable at the strangest hours, sometimes in the middle of the night. :-) Perfect, I can recommend it.
