My daily I/O graph is almost at the limit . The question is what is I/O graph . I tried to find what is daily i/o in infinityfree knowledge base . But i couldnt understand what it is . Can anyone explain in a simple way what cases my I/o graph to go up ( and it is almost at the verge of hitting the limit ) .
Is it that due to visitor or due to constant changes in my site or something else ?
