Re: [dtrace-discuss] How to dig deeper
The buffer cache was already huge. So I decided not to increase it. There is a KEEP pool of 5G which is hardly used. If needed I will sacrifice this cache and add it to the DEFAULT cache. Until now it looks promising. The average log file sync wait time has dropped from about 70ms to 7ms. But we will see how things devellop. Thanks so far to everybody who helped.

Re: [dtrace-discuss] Is the nfs dtrace script right (from nfsv3 provider wiki)?
Hello, Are you referring to nfsv3rwsnoop.d? The TIME(us) value from that script is not a latency measurement, it's just a time stamp. If you're referring to a different script, let us know specifically which script. Sorry, when i did write latency, i did assume that you will know that i was talking about the nfsv3rwtime.d script. Sorry... i mean, that is the script in the wiki page to see the latencies. The: NFSv3 read/write by host (total us): and NFSv3 read/write top 10 files (total us): are showing that numbers... Thanks a lot for your answer!

[dtrace-discuss] Is there a way to clear Dtrace arrays?
I am using trunc(@agg,0) to clear an aggregation every 'n' seconds. Is there a similar function to clear an associative array? I know I can deallocate memory for an individual element by setting is to zero, but I am looking for a way to clear ALL elements in an array. -- This message posted from opensolaris.org ___ dtrace-discuss mailing list dtrace-discuss@opensolaris.org

Can you explain what you're doing a bit so we can understand the use case for such a function?
