Appendix 4. Benchmark of Tomabechi's "ppmpqs.exe"

(March 05, 2001)

The program "ppmpqs.exe" programmed by Mr. Satoshi Tomabechi is one of the most powerful factoring tool and very easy to use.
I have been using this program for factoring during many years, and I collected many data of the execution time of factorization.
The following data covers the range from 81 digits to 93 digits.
The computing environment :

CPU : Pentium III 650MHz, memory 128MB
OS : Window 98

Please refer these data for estimate the time before factoring the number,
