How to Make Your Spring Boot App Run 25× Faster
Jos Roseboom and I are going to take the worst possible Spring Boot application and optimize it live, step by step.
You'll see how JDBC batching and the PostgreSQL COPY command take the data import
from 24 seconds to 842 milliseconds, and how lazy loading and Keyset Pagination take a page
that loaded in 6.76 seconds down to 89 milliseconds.
Right after the webinar ends, I'm going to send the giveaway coupon to my newsletter subscribers, so stay tuned for an awesome gift!
