数据存储区放置的延迟约为 150 毫秒 - http://code.google.com/status/appengine/detail/datastore/2010/03/11#ae-trust-detail-datastore-put-latency。
将数据大小为 100 字节的单个数据存储放入只有 1 个属性且没有索引的实体中,大约使用多少 CPUTime?
另外,有谁知道将这个数据存储放入任务队列会产生多少额外的 CPUTime 开销?
我计划今天晚些时候对此进行一些测试以找出答案,但如果有人已经知道这会对我有所帮助:)。
注意:这是此问题的后续内容:Google App Engine - 日志的可靠性如何?。
The latency for a datastore put is about 150ms - http://code.google.com/status/appengine/detail/datastore/2010/03/11#ae-trust-detail-datastore-put-latency.
About how much CPUTime is used by a single datastore put with data size of 100 bytes, into an entity that has only 1 property, and no indexes?
Also, does anyone know about how much extra overhead in CPUTime doing this datastore put through the task queue would be?
I plan to do some testing with this later today to figure it out, but if anyone already knows that would help me out :).
Note: This is kind of a follow up to this question: Google App Engine - How reliable are the logs?.

正如发帖者在评论中所说,单个数据存储放入大约需要 75 毫秒的 CPU 时间,以及大约相同的延迟量。
As the poster said in the comment, a single datastore put takes about 75ms of CPU time, and about the same amount of latency.
