> Problem:
> The function t3lib_db->escapeStrForLike() is using preg_replace to escape
> the values '%' and '_' with a '\' for a sql-like-statement.
> preg_replace takes a lot of recources and is not necessary for such a
> simple replacement.

> Solution:
> use str_replace instead.

First of all, thanks for your different DB patches.

I'll have a look at all those DB-related patch soon.

May I kindly ask you to create .diff files instead of .patch and make 
sure they are attached as text/plain to your posts? This helps a lot 
with mail readers such as Thunderbird or Postbox that allow inline 
viewing of text attachments with syntax highlighting.

Regards

Xavier
