Is there any way to make that larger? Goal: I'd love to try putting the external log on an SSD that could sustain two or three minutes of steady full-throttle writing. 128MB gives me less than a second worth of writes before my write speed slows down to the underlying storage speed. I'll do lots of benchmarks before rolling it out to make sure it actually does help, of course. I just want to know if it's possible, and how to do it if it is. Thanks.
