Back in the day, contemporary reviewers called the Indy an 'Indigo without the go'. The R5000 chipset certainly helped matters, especially on the higher end, but even a 150MHz Indy lags well behind the performance of a low-end O2.

What you've got is a low end Indy, unfortunately. It doesn't have the R5K, your amount of system RAM is definitely a limitation, and even with an older version of IRIX I'm afraid it can only do so much.
