hi, im having serious speed issues on a site. my app is a python app and im using torndadoweb to serve requests. the actual rendered html is also store in the datastore and memcache. a decorator on the GET request checks first if there is a memcache entry if it exists it writes the html out, if there is no memcache entry it tries to get it from the datastore and only if that doesnt exist too it executes the handler.
what i noticed is that the simple get from the memcache until the page displays on the browser takes way too long and i actually dont understand how this is possible. here is my stats result:
what is actually taking 6seconds here????
my decorator looks like this:
def cache_page(with_keywords=False, keywords=None):
def decorator(method):
def wrapper(self, *args, **kwargs):
uri = self.request.uri.strip()
cachekey = '%s|%s' %(appversion, uri)
cached = memcache.get(cachekey,
namespace='cachedpage|%s'%appversion)
if cached:
self.write(cached)
return
page = CachedObject.all(keys_only=True).filter('appversion =',
appversion) \
.filter('uri =', uri).get()
if page:
p = db.get(str(page))
self.write(p.html)
memcache.set(cachekey, p.html,
namespace='cachedpage|%s'%appversion)
return
else:
...
return method(self, *args, **kwargs)
return wrapper
return decorator
this shouldnt take that long right?
any thoughts?
thank you<<inline: Screen shot 2011-10-13 at 10.22.38 AM.png>>
