SunSoft Inc has tweaked Solaris 2.5.1 for Web serving, claiming that Netras running the version used at Netscape Communications Corp handle 18 million hits a day at half a cent a hit compared to one cent per hit for Digital Equipment Corp’s TurboLasers on site at Netscape and two cents each for the IBM Corp and Hewlett-Packard Co boxes. The 2.5.1 Web revision is out next month. It provides go-faster service for Apache and other Web servers, not just for Navigator. What it doesn’t say is that it will also run SunSoft’s own Vishnu Web server software at a greater pace. SunSoft is understood to have been working on its own Web server software for some time but shelved a planned release earlier this year because what it had at the time really didn’ t cut it.
