There may be multiple reasons for this behaviour.

• How many monitors do you have
• what is their composition
• what does your storage system under uptime-kuma look like
• how much cpu has your server and are there any noisy neighbours

the v2 release does fix most of these issues by allowing for mariadb as another storage option (plus a few misc. performance optimisations, like #2750 or #3515).
