I have yet to collect data under varying loads, however I have
collected performance data for 8GB shared buffers which shows
reasonably good performance and scalability.
I think the main part left for this patch is more data for various loads
which I will share in next few days, however I think patch is ready for
next round of review, so I will mark it as Needs Review.
I have collected more data with the patch. I understand that you
have given more review comments due to which patch require
changes, however I think it will not effect the performance data
to a great extent and I have anyway taken the data, so sharing the
same.
Performance Data:
-------------------------------
Configuration and Db Details
IBM POWER-7 16 cores, 64 hardware threads
RAM = 64GB
Database Locale =C
checkpoint_segments=256
checkpoint_timeout =15min
scale factor = 3000
Client Count = number of concurrent sessions and threads (ex. -c 8 -j 8)
Duration of each individual run = 5mins
All the data is in tps and taken using pgbench read-only load
Common configuration remains same as above.
Forgot to mention that data is a median of 3 runs and attached
sheet contains data for individual runs.
Hi Amit,
Results look pretty good. Does it help in the read-write case too?
Cheers
Mark
