From 73c711243382a48b9b67fddf5ed9df2d1ee1be43 Mon Sep 17 00:00:00 2001 From: Erik Johnston Date: Thu, 2 Jun 2016 11:29:44 +0100 Subject: Change CacheMetrics to be quicker We change it so that each cache has an individual CacheMetric, instead of having one global CacheMetric. This means that when a cache tries to increment a counter it does not need to go through so many indirections. --- synapse/util/caches/expiringcache.py | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'synapse/util/caches/expiringcache.py') diff --git a/synapse/util/caches/expiringcache.py b/synapse/util/caches/expiringcache.py index 2b68c1ac93..080388958f 100644 --- a/synapse/util/caches/expiringcache.py +++ b/synapse/util/caches/expiringcache.py @@ -13,7 +13,7 @@ # See the License for the specific language governing permissions and # limitations under the License. -from synapse.util.caches import cache_counter, caches_by_name +from synapse.util.caches import register_cache import logging @@ -49,7 +49,7 @@ class ExpiringCache(object): self._cache = {} - caches_by_name[cache_name] = self._cache + self.metrics = register_cache(cache_name, self._cache) def start(self): if not self._expiry_ms: @@ -78,9 +78,9 @@ class ExpiringCache(object): def __getitem__(self, key): try: entry = self._cache[key] - cache_counter.inc_hits(self._cache_name) + self.metrics.inc_hits() except KeyError: - cache_counter.inc_misses(self._cache_name) + self.metrics.inc_misses() raise if self._reset_expiry_on_get: -- cgit 1.4.1
