ChunkHost performance review
Recently, I received a free 128MB chunk (That’s what they call a VPS) with 3GB storage and 35GB bandwidth per month for free. They says that its free for lifetime, if put into some use. My plan is to use it for delivering this site, which runs on wordpress, along with few other stuffs.
128MB RAM is very limited and there is no extra burst memory available. But, being a XEN VPS, I hope to get a satisfactory performance. The first thing I did was to measure the performance using UnixBench benchmark suite and the report is as follows.

System Benchmarks Index Score 1023.6
The score is not that bad, more than satisfactory for a free server, but comparatively lower than the servers I use. The plus point is that, it can be used as a testing place for deploying projects in a limited resource platform.
You can get your chunk for free from here. (Its a referral link :-))
