I would recommend doing a hard reset and taking out the battery for a minute, then see how well it works.

If it's still sluggish, I would then flash the newest stock rom (made by Sprint for normal use) then flash the ROM that you wanted. Also make sure you have the newest radio, or the one most compatible with the ROM you are using.

Also keep in mind that some ROMS will need more attention, just like on your pc if you open a bunch of programs, you may have to go in and close them out completely. Alot of the time, exiting a program doesn't close it out and it is probably still running in the background. You would then have to go into a taskmanager and close all programs.

If that's the case, resetting your phone once a day will help it stay running smooth.
