Re: Sybase 11 TPCC on DEC (your comments please)

The TPC specification is on the Transaction Processing Council WEB site (http://www.tpc.org/bench.descrip.html) Have a look In article <4cf1c6$io@nova.dimensional.com>, cjames@melchizedek.cec-services.com wrote: > cjames@melchizedek.cec-services.com (The Right Reverend Colin James > III) posted with deletions: > > > | If a 300 MHz Alpha is linearly equivalent to a 133 MHz Pentium (which > | it may not be), then 300/133 or about 2.25 * 3360 tpm = 7580 tpm which > | is about 45% less than the Sybase mark.
