Simple but clumsy test:
Multiple backends all doing single row inserts into private tables. Run it
for a fixed time period and add up the total number of rows. Do this for both
a small (eg 2) and large (eg 20 or 40) number of backends.
psuedo perl /sh / sql follows
# driver <number of users> <delay time> <run time>
synchtime = timenow
starttime = synctime + delaytime;
endtime = starttime + runtime
for user 1 to number of users
singleuser synchtime delay_time run_time
# singleuser <userno> <starttime> <endtime>
exec sql 'create table user$user (i int);'
sleep until start time
n = 1;
while timenow < endtime
exec sql "insert into user$user values($n);"
print "user $user inserted $n"
The figure of merit is the total number of inserts. Oh and that the system
does not fall over.
But, it may be best to leave this until after the mega patch. I am not sure
I want to share the blame ;-).
Just to fill me in, where does the mega patch fall in with the next release
snapshot? That is, if this misses the mega patch is it waiting until 6.4?
