Hello,

In our application, we noticed some time ago that refreshing a Table is a bit slower than before, since we used Markup in it.
After some investigations, it seems Markup Validation is the culprit

For example, during a typical test, refreshing a Big table takes 2 ms without markup, 2 ms with markup and validation disabled, and takes 350 ms with markup and validation.

Even performances remains acceptable, it is a bit anoying for us, so I will in my case probably disable markup validation and apply validation by myself, only for columns that can contain unsafe markup.

No issues here, I am just wondering if you think org.eclipse.swt.internal.widgets.MarkupValidator itself could be improved, so in this case I would probably spend some time on it, in order to propose a patch.

Regards,
Arnaud

Hi Arnaud,
yes... this is a known issue and we want to improve the performance of
MarkupValidator. Currently, it's based on standard SAX parser, which is
probably the culprit. Improvements (quality patches via Gerrit [1]) in
this direction are welcomed.

Thanks,
