For example, if the database can only process 10 messages at time, increasing the JMS listener Max session from 20 to 30 will not improve performance.
例如,如果数据库一次只能处理10条消息,那么将JMS监听器最大会话数量从20增加到30将不能提高性能。
DDS has both the advantages of high frequency resolution, rapid frequency change rate and low phase noise and the disadvantage of bad spur suppression performance with Max value of -65 dB.
DDS的优点是具有极高的分辨率、频率转换速率快、相位噪声低等;缺点是杂散度抑制比性能差,很难做到- 65 d B。
