Just to be clear, are you saying that *while* packing, zope will slow down (which is what I think you are saying) or that subsequent to packing, zope will stay slowed down (which is what I think Thomas is saying)? I don't see why the latter would be true.
Zope writes the packed data into a new file, renames the original file to Data.fs.old, and renames the new packed file to Data.fs. The question is: what can make one new file slower than an old one in the same directory? I guess there are lots of system-dependant things; fragmentation, or moving over to a slower disk if this filesystem is on LVM. Alternatively, packing is quite memory intensive. Its possible that packing could leave your zope process with fragmented memory. Try restarting the zope server.
It will be slower until the object cache has been filled up again, right?
No. Everything else, including the object cache, is unaffected by packing. Toby Dickenson tdickenson@geminidataloggers.com
