Task #1236
Story #1232: Performance issues - testing and improvement
Highly variable response times from cn.dataone.org
0%
Description
Performing listobjects on cn.dataone.org works but the response times are highly variable.
Seems likely to be a caching issue, but likely also related to the query being executed in Metacat to generate the listObjects response.
For example:
Nomadini:~ vieglais$ time curl "http://cn.dataone.org/cn/object/"
