Optimizing postgresql table for more than 100K inserts per second

• Create UNLOGGED table. This reduces the amount of data written to persistent storage by up to 2x.
• Set WITH (autovacuum_enabled=false) on the table. This saves CPU time and IO bandwidth on useless vacuuming of the table (since we never DELETE or UPDATE the table).
• Insert rows with COPY FROM STDIN. This is the fastest possible approach to insert rows into table.
• Minimize the number of indexes in the table, since they slow down inserts. Usually an index on time timestamp with time zone is enough.
• Add synchronous_commit = off to postgresql.conf.
• Use table inheritance for fast removal of old data:

Send email from Cloudflare Workers via MailChannels

Cloudflare announced a partnership with MailChannels that allows you to send free email via workers.

The example code that MailChannels supplied wasn't working so I fixed it here to make testing easy.

1. Add include:relay.mailchannels.net to your domain's SPF record.
2. Update the code below with your email addresses
3. Create worker, paste code, save and deploy and test

# set the Windows Update service to "disabled"
sc.exe config wuauserv start=disabled

# display the status of the service
sc.exe query wuauserv

# stop the service, in case it is running
sc.exe stop wuauserv

# display the status again, because we're paranoid
