Slow deployments when the server is running for long periods
darkcode85 opened this issue · comments
Hi,
After having a server running for 2/3 weeks the deployment process is very slow, when the server is initially created the deployment takes 1-2 minutes to finish, after 3 weeks the deployment process takes +10 minutes to finish. This process is incremental so after 2 weeks it takes +5 minutes to finish and getting worse if the server is running for more time.
Reviewing the log files I have noticed that the set user to deploy is taking +1 minute each time it is executed when the server is running for 3 weeks, initially the set user to deploy was completed in 10/20 seconds.
Deployment log when the server is created - (set user to deploy completed in 10/20 seconds)

Any idea/reason why the set user to deploy is taking so long to be completed each time it is exucuted after having the server running for +3 weeks?
Honestly - I have no idea. It shouldn't take that long. Does your project grows over time (i.e. it's adding new logs or a lot of other small files)? Have you tried to set ownership manually by SSHing to the server? Does it take so much time as well?
Finally I found the cause of this issue, this was caused by the bootsnap gem creating multiple files on tmp folder. I have just removed the bootsnap from production env.
