You'd do best to ask that of the vendor, but it looks really low to me. I'd expect you to need at least 512Mb, probably more like 1Gb.
You can always turn on cache advice and see what that says about the effect of changing it, but i'm betting that if you have free memory on your system then you're going to be increasing that shared pool size real fast.
My laptop instance has a larger shared pool than that, and it's got to share 1Gb with all the other crap i use.
