[josm-dev] josm/jmapviewer / tilecache / single directory
Hi, i send an email a couple of months back about the jmapviewer tilecache used by josm using a flat directory for storing the tiles. Today now i stumbled that doing a find in the .josm directory takes upwards of 10 Minutes on my Quad i7 with a 7200 IDE Disk on Debian/Wheezy. Doing a cache cold ls in ~/.josm/tilecache/Bing Aerial Maps takes flo@p2:~/.josm/tilecache/Bing Aerial Maps$ time ls /dev/null real9m3.151s user0m23.133s sys 0m26.474s flo@p2:~/.josm/tilecache/Bing Aerial Maps$ ls -1 | wc -l 1846091 9 Minutes 3 seconds for a ls - 1.8Mio files in a single directory. Flo PS: Dont get me wrong - large cache is good - but not like this. -- Florian Lohoff f...@zz.de signature.asc Description: Digital signature ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev

Probably cache clean is broken, if so, please open a bug? I am living behind a 384KBit/s DSL and loading tiles is a pain in the ass as it takes ages to fill a screen with tiles. So a large cache is VERY WELCOME. It got that large because i was active in northern china which is a huge area. I want that much data in my cache - But storing it into a single directory is - uhm - broken - Filesystems are bad in storing huge amount of files or directories into a single dir. This is why all caches typically organize their files into trees - e.g. squid. Normally josm had its cache dir set to something in /tmp which is even more broken as /tmp is typically a tmpfs on most architectures. So using josm fills up memory and swap and cache is deleted on reboot... As sane default could be ~/.josm/tilecache but not a single directory.
