Is it normal that I get half the hashrate I normally get in cgminer?

Yes, scryptn/vertminer you generally get about half of your normal hashrate for scrypt.

The amount of hash/s you will get for any scrypt coin is based on the n-factor. For example, Litecoin has an n-factor of 10 and it does not change. CAI has adjusting n-factor that increases over time so when the n-factor changes you need to adjust your miner settings to utilize as much gpu and system memory as possible. If n-factor of Litecoin was to increase +1 to 11 then it would take twice as much memory to mine so your hashrate would decrease by half ( a bit more actually). This hash rate would be reduced by half each time the n-factor increases +1. At n-factor 13 or 14 the amount of memory required to hash a scrypt coin makes cpu mining more feasible as you can access more system memory. The current n-factor of CAI is 11, so it is important to allow access to system virtual memory (page file), your hashrate can increase as much as 10% if manually setting virtual memory (using Windows) to a higher amount even if Win does not say it is actually using it.
