Is there any difference between the web project compiled by idea and myeclipse?

take over an old project. One of the functions is to accept TCP requests, parse the parameters and store them in the database
project before using MyEclipse10. Because I am accustomed to using idea
project, after the completion of the project, the parsing function is very slow, with a delay of nearly 1 minute.
I copied the project code to someone else and recompiled the
delay with MyEclipse2014. Why does the delay no longer exist? The
project is updated on the original basis, that is, directly replace the class file under web-inf.
idea configure Artifacts for Web Application:exploded, to find classes
myeclipse in the out directory, that is, to find classes in the tomcat > webapp that comes with it. Is there a problem here?
I used BCompare to compare two .class files compiled by ide, both of which are exactly the same

production environments should not rely on IDE compilation, but should use tools such as maven to compile. Different IDE uses different maven. Coming back to your question, I think there is still something wrong with the code
