Hi Fuhong,

Yes, the Django Template Language is known to be rather slow.

Compiling it is a very hard problem, for two reasons:

- its scoping semantics don't match Python's (unlike Jinja2, for example);

- custom template tags can dynamically implement arbitrary behavior.

The outcome of the latest attempt is documented here:

I'm not aware of more recent work on this topic.

Best regards,

Have you tried using the cached template loader (see https://docs.djangoproject.com/en/1.4/ref/templates/api/#loader-types)?

No, I have several 3rd party apps in my website and I haven't confirmed they are "thread safe". I'll check this later. Thanks:D
