Just the one time. One thing you have to keep in mind though.
You can only get one stat up to 255 points by ev training. Those last 3 point are useless. You can only have a maximum of 510 EVs over all. So, 252 in strength, 252 in health and 6 in speed would take up all the evs, while allowing you to get an optimal bonus. Of course, what you want to invest in will differ on the pokemon and what you're aiming for, but that's up to you to decide. Serebii and smogon can be good guides for this, but keep in mind that smogon takes itself way too seriously unless you're doing tournament stuff within their guidelines.
Edit : Overall, since 252 divided by 4 is 63, that's the most you can expect to change your Pokemon's stats. Going further than that, you have IVs and nature which you want to look into before EV training usually but that's a whole other league of overcomplicated kids game math.
