1) I was able to upgrade to PHP 5.4 easily to speed up the site but was not able to see that php memory is increased to 128M
2) I've done the things mentioned in the link (creating folders and phprpc file) But seems like my php memory limit is not increased to 128M yet). Have read online that php memory can be set at .htaccess or config file also. Do you suggest to try these. Sorry, I'm not a techie, so lil cautious with my attempts
3) Also just not to take advantage of your servers/data i just want to know if 128M is what the max limit i can go for. Can this be set to 200M or 256M also ?
