In January, I announced our TPoX benchmark that became public on
tpox.sourceforge.net. We just had its next release.

What is new?

(1) TPoX 1.1 contains six sub-document XML level updates.

(2) The data generation now also produces XML fragments for
"accounts". These are required by Update2 which inserts new accounts
into existing custacc documents.

(3) The workload driver has new options -pc, -cl and -m.
-pc <n> computes the n-th percentile of the response times for
each transaction type.
-cl <l> computes the confidence interval with confidence level l
for the response times of each transaction type.
If -pc and/or -cl are used, then by default 50MB of main memory
are used to collect and compute these statistics. The -m option can be
used to change the memory.

(4) The workload driver also has the following enhancements:

- Enhancements to support the new updates, in particular Update2
which inserts a new account into an existing custacc document.
- Two new lists with possible parameter values
- Shows throughput in transactions per seconds (in addition to the
previous transactions per minute)
- Shows number of result rows returned for each query if verbosity
level 2 is used.
- Allows XML inserts into CLOB columns (for comparison purposes).
- Allows uniformly distributed decimal values as input for parameter
markers in query predicates.
- Various bug fixes (see https://sourceforge.net/tracker/?gro...5&atid=915227).

(5) Small correction in the data generation for "orders":

(6) Updated documentation to reflect all of the above.
