This machine has 2.5Mb memory and 2 cpus in it. We are a company that runs tbl | troff -ms |pipes for up to 12 hours every night (sometimes during the day) for our Xerox 8700 laser printer, producing 50 or 60 40-page documents a day. Each document currently takes 8 to 10 minutes in the format pipe. Obviously, it would be of great value to us if we could improve the performance of troff. We tried compiling it (troff) with the in-memory compile flag set, but this caused our machine to page fault like crazy and made troff run 70% SLOWER. Our working set ratio allows the machine to expand memory fully until there is no more available; since the test ran on an otherwise empty machine, it is hard to believe it ran out of memory. We have contacted HP technical support in Ft. Collins and are waiting for a response. I would guess this is an HP problem. Has anyone had any success with the in-memory compile flag? If so, what was the performance improvement? Does anyone have any suggestions for us? Does anyone know of any versions of troff that have been modified or rewritten to improve performance? (You mean someone that actually looked at and (gasp) MODIFIED troff code?) Thanks in advance. Rich Baughman The Consumer Financial Institute (a.k.a. C.M.
