[Swift-devel] How to the maximum number of concurrent jobs allowed on a site to a fixed size?

[Yi Zhu]

Hi, all

As we've already know, Swift dynamically change the maximum number of 
concurrent jobs allowed on a site based on the performance history of 
that site. According to swift Document: Each site is assigned a score 
(initially 1), which can increase or decrease based on whether the site 
yields successful or faulty job runs. The score for a site can take 
values in the (0.1, 100) interval. The number of allowed jobs is 
calculated using the following formula:

2 + score*throttle.score.job.factor

We can change the throttle.score.job.factor in sites.xml or 
swift.properties files, but since the "score" value can be 
increased/decreased during the execution, It seems that we can not 
really set the maximum  number of concurrent jobs allowed on a site to a 
fixed number. Anyone have any idea of that?


Many Thanks.
