I tested the srcipt with both cygipc-1.09 and my patched cygipc-1.09
(Where have my postings on Feb 6 gone ?).
With about 20 concurrent clients running
1) cygipc-1.09
Handles 9000 ---> 23000 or so.
2) my patched
Handles 9000 ---> 15600 or so.
So at least one of the cause seems the semaphore handle leak
in the cygipc library.
regards,
Hiroshi Inoue
