title: "Postgres database slowdown"
date: 2017-06-20 19:28:00 +0200
categories: postgres performance

Today I've encountered strange performance degradation after some time running Postgres server.
The situation was as follows:
* PostgreSQL 9.6 running on Ubuntu 16.04
* server running under load (but not too much)
* queries were getting slower after some time
* running `top` showed that `postgres` process was using around 90% CPU (on quad-core machine)
After running `strace -c -f -s 256 -o strace.log postgres` I found that `select()` calls were taking up most CPU time (around 90%):
% time seconds usecs/call calls errors syscall
------ ----------- ----------- --------- --------- ----------------
91.98 28704489.02 30 949687785 select
...
After looking through PostgreSQL documentation I found that by default `select()` system call is used by server processes as IO multiplexing mechanism.
Then I tried enabling TCP keepalive (see [PostgreSQL documentation](https://www.postgresql.org/docs/9.6/static/hot-standby.html#STREAMING-SERVER-PARAMETERS)):
sql
ALTER SYSTEM SET wal_receiver_status_interval = '1s';
ALTER SYSTEM SET wal_receiver_timeout = '60s';
After restarting PostgreSQL I saw that `select()` calls were taking less than 10% CPU time.
I'm not sure what was causing such huge slowdown but my guess is that some clients were not sending keepalives properly or TCP keepalive was disabled.

date: 2020-12-29 09:00:00 +0100
categories: ipv6 networking linux bash

In this post I'll show how to generate random IPv6 address using Bash.
Generated addresses will have following properties:
* global unicast address (first bit is set)
* RFC4193 privacy extensions (random bits)
* prefix length between `/64` and `/96`
Here's full script:
bash
#!/usr/bin/env bash
# Get RFC4193 prefix (FFXX)
# https://tools.ietf.org/html/rfc4193#page-2
prefix="ff"
# Generate random bits between /64 and /96 (inclusive)
random_bits=$(( RANDOM % (2**32) ))
# Combine prefix with random bits into proper hex string
address="${prefix}${random_bits:0:8}${random_bits:8:8}::1"
echo "$address"
You can run it like this:
bash
$ ./generate_ipv6_address.sh
fd23b1cc016a0001::1
$ ./generate_ipv6_address.sh
fc0d8c1b44b20001::1
$ ./generate_ipv6_address.sh
fe84f31aafbc0001::1
$ ./generate_ipv6_address.sh
ff8c420e58a60001::1
$ ./generate_ipv6_address.sh
ff73d88ecbf80001::1
$ ./generate_ipv6_address.sh
ffac8f89856d0001::1
$ ./generate_ipv6_address.sh
ff9611e41a720001::1
Note that this script generates only one half part (`A:B:C:D`) of IPv6 address.
This is because full IPv6 address would have form `A:B:C:D:E:F::G:H`.
And last half part (`E:F::G:H`) should be zero or should contain interface identifier.
To get full address you need either manually append last half part or use some existing address.
To generate full IPv6 address using existing address you can do something like this:
bash
#!/usr/bin/env bash
# Generate random RFC4193 prefix
random_prefix=$(./generate_ipv6_address.sh)
# Get existing address (e.g., from /etc/network/interfaces)
existing_address="fe80::2f5e:a8ff:fef5:bff2"
# Replace prefix in existing address with generated prefix
address=$(echo "$existing_address" | sed "s/^fe80([:/])/${random_prefix}1/")
echo "$address"
You can run it like this:
bash
$ ./generate_full_ipv6_address.sh
fd23b1cc016a0001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
fc0d8c1b44b20001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
fe84f31aafbc0001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
ff8c420e58a60001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
ff73d88ecbf80001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
ffac8f89856d0001:f5:e8:a8:f5:bff2
$ ./generate_full_ipv6_address.sh
