[UNC?] Slow Page Load With Cache on Remote Drive
Build ID: 0.9.x and 2001070808 My profile is stored on a remote drive (through Windows SMB). If the cache is enabled, graphically intense sites such as www.cnn.com and especially us.buy.com can take up to 60sec to load (buy.com), and 3sec to load when the cache is disabled. I had my profiles stored the same way in 4.x with no performance problem. Any ideas? Thanks!
There maybe a difference in the composition of memory/cache. Does performance improve if you turn off cache? I've asked Profile about this configuration in bug 90682.

Does anyone think this should be relnote?
Why would you want your cache to be on a different computer than the one you're browsing on? See bug 74085 for making Mozilla default to always using a local cache...
reporter: what does your cache directory for 4.x look like? I'm wondering if it might have effectively been disabled, which would have given it performance more similar to the 6.x uncached time you reported.
Target Milestone: --- → mozilla0.9.6
Are you using a mapped drive or UNC for your cache directory?
Summary: Slow Page Load With Cache on Remote Drive → [UNC?] Slow Page Load With Cache on Remote Drive
The cache is on a mapped drive (on a SMB share on a Linux server). I keep my profile on it, so I can switch between two windows machines here at home. My main problem was that Mozilla wouldn't let me switch my cache to another directory. I worked around the problem by just disabling the cache (which works fine since I'm sitting on a wireless connection that equates to about 2/3 of a T1. If you would like to put this one off for a bit in favor of more critical bugs, you're welcome to. I'm working fine. I do think others in the same situation as me might experience the problem in the future. Thanks!
Ah, interesting. In 4.x was your cache folder in you profile folder or was it located elsewhere. There is a pref availabe to specify the location of the cache parent directory (browser.cache.disk.parent_directory), but there isn't any UI to set it yet (bug 46490).
Necko will be focusing on performance for 0.9.7.
Target Milestone: mozilla0.9.6 → mozilla0.9.7
I just ran our page load tests against 4.7 on a Win98 machine, comparing local and remote profiles. The local profiles performed much better. The remote profiles (and remote cache directory) also performed worse on revisiting pages over our fast network. This result was expected and matches our findings with 6.x. I was unable to reproduce the huge discrepancy reported between the cache being enabled or disabled (60 sec vs. 3 sec). We'll continue trying to improve cache performance, but I don't think we're doing anything egregiously wrong with respect to remote cache directories. Marking WONTFIX.
