I realised that all text will be purified when rendering blocks in a view(page). This will cause this problem if a page contains lots of artefacts.
My solution is a text will be cleaned right after adding into a artefact. 
 - Many text fields in artefacts have limitation of 64k characters. This should not cause max execution time exceeding.
 - There is only  HTML file block may cause the problem as HTML file can be big (>300k). In this case the system should raises an error message to ask the user simplify the HTML file before add it into the page.

Any discussion?

Title:
  Time out error when text box has heavy HTML

Status in Mahara ePortfolio:
  Confirmed

Bug description:
  The following error comes up when trying to access a users view

  Fatal error: Maximum execution time of 30 seconds exceeded in
  /var/www/mahara-site-myportfolio-ac-nz/lib/htmlpurifier/HTMLPurifier/Strateg
  y/MakeWellFormed.php on line 395

  The view number is
  http://myportfolio.ac.nz/view/view.php?id=13222

  This view includes text blocks that have been copied and pasted from
  Word without using the Paste from Word button (this is hidden unless
  you go to full screen mode).

  Unfortunately once this happens the content in the view is not able to
  be edited.

  By the way I experimented with the clean messy code button and this
  doesn't seem to have any effect on content pasted from Word - is this
  right?

  Not sure if this is strictly a bug but more using of Word to paste
  content and the htmlpurifier having difficulty purifying the Word
  html.
