我们有atomikos事务管理器的spring-boot应用程序。 问题是当我将它与weblogic解决方案进行比较时，XA事务中的提交需要花费大量时间。
这是我们的应用程序中的指标
process_seconds_count 28072.0
process_seconds_sum 3288.249
process_commit_seconds_count 28072.0
process_commit_seconds_sum 2471.917
所以4/5的处理时间只需提交。我们应该如何优化它？
application.properties：
spring.jta.enabled=true
spring.jta.atomikos.properties.log-base-dir=target/transaction-logs/
spring.jta.atomikos.properties.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory
spring.jta.atomikos.properties.max-timeout=900000
spring.jta.atomikos.properties.default-jta-timeout=90000
spring.jta.atomikos.properties.threaded-two-phase-commit=true
spring.jta.atomikos.datasource.default-isolation-level=2
spring.transaction.default-timeout=900
更新：
从日志中我看到提交和终止状态之间存在巨大差距：
