Just like any test suite, it catches regressions. We saw that it was effective when we introduced certain JSC regressions that it could have prevented. Since some of the errors Sputnik catches are platform specific (32 bit vs. 64 bit, JIT vs. interpreter etc), it is particularly important to have it on build bots.

Some subtests are less interesting (e.g. many Unicode tests basically check ICU behavior), so we have the slowest of those disabled already.

One possible way to speed up Sputnik tests would be to run them as part of run-javascriptcore-tests, avoiding web page overhead. Someone proficient in scripting languages just needs to improve run-javascriptcore-tests to the point when it can do that.
