php - Updating a MySQL table every couple of seconds with large amounts of data? -


i've create application has autosave feature. instead of user having click save button, settings automatically saved every interaction app. behind scenes, every time app changes, post data php , update mysql database table.

it's working nobody's using yet question is: if i'm updating mysql database table save data (and saved data equivalent of 100kb xml file) every couple of seconds, experience performance issues? should noted there hundreds or thousands of users using app @ same time.

any tips or advice appreciated.

bundle , serialize data changes single json object before posting (as single field). fewer large interactions offer better performances constant tiny ones.
