apache2 + hi cpu usage

first sorry everyone for my englisg itsn’t my origin language

today i did install optware on my book live, and in htop i can see that one process jumping with cpu usage

for example every 10-15 sec cpu usage jumping up to 60% only with this process.

usr/sbin/apache2 -k start

im not sure its normal? what is this process for?

btw is possible to flash original fw? if yes how to do this?

If you are using smartware to backup your files, it could use a high CPU percentage while the backup is being made. You can try installing the latest version for better performance.

Yes it is possible to put any factory firmware you want back on the drive. Follow my guide linked below and you should be good to go.
