与脆化温度较高的相比，脆化温度较低的材料在低温下性能保持率较高。

Compared with the plastics that had high brittle temperature, the plastics that had low brittle temperature had a higher retention of property.

同样，在大约600个用户时，Tomcat的性能急剧下降，而基于NIO的服务器的错误率保持相对较低。

Again, Tomcat's performance deteriorated drastically at about 600 users, while the NIO-based server's error rate remained relatively low.
