Performance issues for all users in Odoo 9 when a single user creates a heavy request
Odoo/PostgreSQL optimization
by
Open Source Integrators, Maxime Chambreuil
Hello,
I have a customer with ~300k products and he has been running Odoo version 8 with PostgreSQL 8.3 for almost a year now.
Performance is deteriorating with time and especially during office hours when employees are working.
I would like your input to improve performance based on the info below. If you need more, please let me know.
Odoo and PostgreSQL runs on 2 separate servers, each with 64GB of memory and 8 CPU.
On PostgreSQL:
# hdparm -t -T /dev/mapper/vg01-root
/dev/mapper/vg01-root:
Timing cached reads: 16838 MB in 2.00 seconds = 8425.66 MB/sec
Timing buffered disk reads: 456 MB in 3.02 seconds = 151.16 MB/sec
Kernel config of PostgreSQL:
kernel.sched_migration_cost_ns = 5000000
kernel.sched_autogroup_enabled = 0
kernel.sem = 250 32000 100 128
kernel.shmall = 4194304
kernel.shmmax = 17179869184
kernel.shmmni = 4096
fs.file-max = 262140
vm.vfs_cache_pressure = 50
vm.min_free_kbytes = 65536
net.core.rmem_default = 33554432
net.core.rmem_max = 33554432
net.core.wmem_default = 33554432
net.core.wmem_max = 33554432
net.ipv4.tcp_rmem = 10240 87380 33554432
net.ipv4.tcp_wmem = 10240 87380 33554432
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_sack = 1
net.core.netdev_max_backlog = 5000
net.ipv4.tcp_mem = 786432 1048576 26777216
net.ipv4.ip_local_port_range = 1024 65535
net.ipv4.tcp_max_tw_buckets = 360000
As the postgres user:
$ ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 257588
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 65535
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 257588
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
odoo.conf extract
limit_memory_soft = 2412592128
limit_memory_hard = 4560075776
limit_time_cpu = 86400
limit_time_real = 172800
max_cron_threads = 1
proxy_mode = True
workers = 6
postgresql.conf is attached.
During office hours, opening the product list (80 records) takes 5 sec. Running sales report (product category by week) takes 20 sec. I never succeeded to get the inventory valuation report.
Outside office hours, waiting time is divided by 2.
If you have any suggestions, it would be very much appreciated.
Thank you.
