Spring controllers vs HttpServlet performance-wise -

i'm working on java web app simple web layer based on httpservlet (classes inherit httpservlet class). app real-time app, meaning functionality measured (among rest) response time.

i utilize spring controllers (dispatcherservlet) instead of current servlets. should expect same performance?

simple reply no

spring controllers "c" part of mvc , based on servlets; , spring's dispatcher servlet loads info , forwards request matching/corresponding controller request processing.

while servlets base of operations of java web application; there minimal overhead there.

spring performance servlets controller
