Could you state what Solaris-x86 version that was?

At a previous job, I was able to replace 9 slowaris boxes with 4 linux boxes, and even then, just one of the Linux boxes could handle the complete load it took the 9 slowaris boxes to run. I will note that if you are going to use slowaris, I highly advise you set a memory key rather than using on disk cache for BDB if your DB is any size over about 4 GB. Other than that, you'll generally just have to deal with the fact it will be signif! icantly slower than Linux.
