***

research:

memory allocation for identical strings in different instances of the same class (do static strings each consume extra memory or is it just a reference to the original string? is there any behavior differnce between class and script attributes? is there a global string pool or different sub groups by class or script or method)

add to infra:

grafana?

sentry? datadog? posthog?

***

## Infrastructure:

1 vm for wordpress&#x20;

1 vm for java
