然而，大多数请求这个数据的应用程序使用了一定程度的缓存，因为网络往返开销很昂贵。
Most applications that request this data, however, employ some form of caching, as network round-trips are very expensive.
存储过程可以封装多个SQL语句，有助于避免网络往返。
Stored procedures can help to avoid network round trips by encapsulating multiple SQL statements.
就是因为这种往返的要求和回应，导致了网络的延迟。
The time taken for this round-trip of request and acknowledgment determines the network's latency.
每个从网络到数据库服务器的往返行程从性能角度来看是昂贵的。
Each network round trip to the database server is expensive in terms of performance.
只要用户授权，Flex应用程序就能在客户端上缓存任意大小的数据，这在接下来的会话频繁请求相同的数据时减少网络数据的往返。
With the user's permission, a Flex application can cache unlimited data on the client side, which reduces network round trips if the same data is requested again in the same or future sessions.
然而，对于一些高速网络，如千兆位的以太网和万兆位的以太网，预期的往返时间(因此重新传输超时)要低得多。
However, with high-speed networks, such as Gigabit Ethernet and 10 Gigabit Ethernet, the round-trip time (hence retransmission timeout) is expected to be much lower.
我也在往返的车上和普通的乘客在车上一样，用3g和4g进行了网络连接，并将这些所有的结果平均起来。
I also used 3g and 4g connections on a moving commuter train and as a passenger in a car and averaged all the results together.
结果呢，对于单一的RPC请求，客户端仅需要一个网络往返。
As a result the RPC client needs only one network round trip for a single RPC request.
为了缓解TCP拥塞控制机制对于往返时间(rtt)较小流的偏向问题，现有方法在网络拥塞程度严重时由于对rtt较大流的过分保护而不能有效地工作。
To mitigate the bias of TCP congestion mechanisms to short RTT flows, the existing methods cannot work well when network congestion level is high due to the over protecting to long RTT flows.
虽然这省去了与服务器之间的往返过程，但是这必须与通过网络发送凭据所固有的安全风险进行权衡。
While this saves a round trip to the server, this must be balanced against the security risk inherent in sending credentials across the network.
虽然这省去了与服务器之间的往返过程，但是此性能收益必须与通过网络发送凭据所固有的安全风险进行权衡。
While this saves a round trip to the server, this performance gain must be balanced against the security risk inherent in sending credentials across the network.
利用有效的缓存机制，可以避免到数据库的网络往返时间，绕过占用很多资源的计算，并节省服务器资源，同时改善响应时间和等待时间。
Effective cache mechanism can avoid round trip time to database, avoid calculations which occupying much time, save server resource, as well as improving the response time and waiting time.
