Did you hear about the small program called "fastfs"? It switches some hidden attributes in Solaris filesystem, so that when fastfs is ON, the file closing operation becomes asynchronous. The current process goes on, and the physical file closing is performed some time later. This is "unofficial" hack to UFS, but: you can find fastfs on Solaris installation disk! Solaris installer uses it, although they say that it's unsafe and not supported. I suppose this could significantly increase the performance in your case, though with less safety. I know that it dramatically increases mailserver performance in case of large number of mailboxes. > Also I am very surprised that SNMP collection/CPU usage did not become a > bottleneck > before the disk.

I'd be interested to take a look into your collector. Though, the one I use in RRFW is fast enough too.
