24.2 various tenses 2 We (1)
present / presented / have presented an emulator, Emug, for reproducing low-performance connections. Since it (2)
was / has been specifically designed
to evaluate applications, Emug (3)
can / will / should be easily used in any kind of context. In fact, Emug (4)
is / has been / was implemented in Java so that it (5)
can / will be used as an emulation facility without being forced to rely on any particular hardware. As (6)
is / has been / was well known, the performance of Java programs (7)
is / was lower
than native-compiled languages, so Emug (8)
represents / has represented / represented a major step forward in enhancing performance. Future research (9)
is / will /
should be dedicated to finding other applications for Emug.
