VPS is better than Shared hosting for Sugar CRM
VPS Hosting is better than shared cpanel web hosting because in shared hosting you wont have any control over the number of processes using the RAM Memory, as a result of which the CRM application do not exhibit uniform performance at all the times. If you have large number of concurrent users (more than 10), shared hosting will surely under-perform and database queries will become extremely slow which affect the overall performance of your website.
But with VPS you will get minimum 256MB of RAM which is enough for CRM Applications. If your number of users exceed more than 12-15, you also have option to go for 512MB RAM or even higher. For SugarCRM Professional and Enterprise VPS hosting is strongly recommended. Once you have a VPS, you can use these same VPS server for your website hosting as well as for hosting other applications. Having your own VPS would not only improve the applications’ usability and performance, it will also free you from paying based on number of users and also allow you greater control over the hosting environment as compare to shared hosting.
