Hello, I'm trying to get XCache 3.0.1 configured so I can use namespacing (prefixing variable names with user id). I haven't activated Litespeed on port 80 yet as I'm trying to get Xcache working with Apache first so I know what works before I move everything to litespeed. I've got APC working well with Litespeed LSAPI (CloudLinux CageFS Suexec deamon) and with ASL's Trotix in front I get download times of a echo "hello world" php script of between 14 and 60ms, which concidering I'm moving from modsecurity + apache where I had times between 50 and 140ms it's very good. When I activate Xcache 3.0.1 however Apache FCGI processes seem to crash quite often, I can't login to the admin page, and I don't get any impression that anything is being accelerated. I've come to the conclusion that I haven't managed to configure it correctly or that I've got something that isn't compatible. Does XCache work with Suexec ? I've read advice here from a few years ago saying that it wasn't compatible (this was XCache 1.3 and older versions of Litespeed). Should I work correctly with the current versions of Litespeed ? Here's my current configuration : Code: [xcache-common] extension = xcache.so [xcache.admin] xcache.admin.enable_auth = On xcache.admin.user = "user" xcache.admin.pass = "mymd5********" [xcache] xcache.shm_scheme = "mmap" xcache.size = 128M xcache.count = 32 xcache.slots = 20K xcache.ttl = 600 xcache.gc_interval = 600 xcache.var_size = 4M xcache.var_count = 1 xcache.var_slots = 8K xcache.var_ttl = 120 xcache.var_maxttl = 300 xcache.var_gc_interval = 300 xcache.var_namespace_mode = 2 xcache.var_namespace = "gid" xcache.readonly_protection = On xcache.mmap_path = "/tmp/xcache" xcache.coredump_directory = "" xcache.coredump_type = 0 xcache.disable_on_crash = Off xcache.experimental = Off xcache.cacher = On xcache.stat = On xcache.optimizer = Off [xcache.coverager] xcache.coverager = Off I'm not sure how the mmap works, I've created /tmp/xcache and set it's chmod to 777 Maybe I shouldn't created that folder ? I created it because I didn't see any files names xcache in the tmp folder. I've read that xcache.mmap_path shouldn't be a folder, and it didn't like /dev/zero either… Here are a few errors I was getting when Xcache was activated : I'm gessing that if I get these errors with FCGID I will also get them with litespeed… I forgot to give my server configuration as some settings refer to this. I've got a total of 32 CPU threads and 256GB of RAM. I want Xcache to make the best use possible of these ressources. Thanks !
