When using Atlassian product in SMB companies, we are experiencing slow response / page load after not using it for 1 day and more. Typically at morning or Monday morning. After few minutes ist working OK. After many days of our testing (reverse proxy, SSD drives for software and database, increasing memory etc) it looks everything is related to JAVA machine on background. Java is cleaning internal structures after not using it for a while. You will not see this behavior in bigger companies where many people are using Atlassian products every minute.
Are there some switches or parameters for JVM we can change at product startup to increase JVM internal cleaning time for maybe 30 hours?
