Subject: Low performance
Download (untitled) / with headers
text/plain 240b
I used this module. Then, after profiling, I realized that this module was my bottleneck. Reimplementing the FIFO queues in a database table in fact improved the performance radically. It's very nice and useful, though. Just not very fast.

indeed. i exp. the same exact thing after upgrading from .3 to .6 of this module. Benchmarks showed a radical departure from performance to serious bottleneck. NRFPT afaict. my guess is the freeze/thaw implementations are suspect. what's esp. irksome is that IPC::Shareable (versions 0.6 or 0.3) have had so little documentation or feedback. ugh... -g

If you comment all the lines in the module that start with word "next" it will increase preformance.
