I would suggest you set the pagefile back to system managed. Except for some unusual situations this will be as close to optimum as to make no difference. Disabling the pagefile is more likely to impair performance than improve it, and it may well cause other problems as well. The pagefile was designed to improve performance and it usually does.
Putting the pagefile on an alternate drive may improve performance. Not that this must be a separate physical drive, not partition which would impair performance.
