Cache Tag Speed

Hi,
I am trying out the Beta Cache Tags for LP 8.5.5. My Test Server is a XServe G5 Dual 2.0Ghz Running Mac OS X Server 10.5.6 with 5GB RAM. Can I please get a few of you to run this code a few times, and post the results, along with what you are running it on: [var:'my_timer' = (integer: _date_msec)] Start: [(integer: _date_msec ) - $my_timer] milliseconds<br> [Cache: -Name='Test',-expires=120] [server_time]<br> [/cache] Finish: [(integer: _date_msec ) - $my_timer] milliseconds<br> Obviously it is never going to be faster to cache [server_time] but that was an easy way for me to tell if the cache was working. I'm wanting to see how long it takes to retrieve something from the cache, so I can decide when it is worth while using. My numbers tend to be around the 155 milliseconds mark.. which I would have thought was quite slow, hence the question. Thanks in advance.

Tested on an Anu Centos Lasso 8.5.5
Average 2-3 milliseconds Tested on an Xserve 10.4.X G5 Lasso 8.5.6 Average 4-5 milliseconds. Although I'm not sure the Xserve runs the beta cache tags. The Centos does.

After 6 hours I am now back over 200 milliseconds. I am testing this on two different machines with similar specs, under similar load, and getting the same results. If I reboot both machines it cache time comes back to 5ms. I can't figure out how to get any stats for what is in the cache, as the Cache List in Siteadmin is empty (I don't think it is supported in the Beta tags) So, at least to me, it looks like the Beta Cache Tags also have issues (Possibly only under Mac OS X 10.5?).

Most likely what you're seeing is the result of the cache tags growing the size of the cache significantly; and/or some pruning process taking up some cycles. When you restart, the cache is cleared and everything speeds up (since there is little in the cache). - Bil -- This list is a free service of LassoSoft: http://www.LassoSoft.com/ Search the list archives: http://www.ListSearch.com/Lasso/Browse/ Manage your subscription: http://www.ListSearch.com/Lasso/ |

If someone can tell me how to better diagnose this problem I'm 'all ears' The page that I am actually trying to cache takes about 400ms to process.. and after a reboot with the beta tags enabled takes 89ms.. but after about 6 hours takes 2000ms. I have turned caching off until I can progress further.

Are you caching the page for every visitor? Or caching a single page for all visitors? And are you storing the cache in a global or in sessions? I'd recommend checking the size of the cache when it starts getting slow and see how much data is being squirreled away... - Bil -- This list is a free service of LassoSoft: http://www.LassoSoft.com/ Search the list archives: http://www.ListSearch.com/Lasso/Browse/ Manage your subscription: http://www.ListSearch.com/Lasso/ |

The cache tags beta has a [Cache_Maintenance] tag that is currently never called, but should be called daily at low traffic hours. You should also make sure to ahve a total cache storage limit set, otherwise the cache_maintenance tag will not do anything. -- Mvh Johan Sölve ____________________________________ Montania System AB Halmstad Stockholm Malmö http://www.montania.se Johan Sölve Mobil +46 709-51 55 70 [hidden email] Kristinebergsvägen 17, S-302 41 Halmstad, Sweden Telefon +46 35-136800 | Fax +46 35-136801 -- This list is a free service of LassoSoft: http://www.LassoSoft.com/ Search the list archives: http://www.ListSearch.com/Lasso/Browse/ Manage your subscription: http://www.ListSearch.com/Lasso/ |

Hi, The page is made up of 11 cached objects, stored globally for all visitors: The page is here: http://www.beerstore.co.nz/search.lasso?Type=Mixed%20Case&Title=Gift%20Ideas The cached objects are 'Search for Beer', 'Top 10 Sellers', and the contents of each of the 9 squares in the table. > > > I'd recommend checking the size of the cache when it starts getting > slow and see how much data is being squirreled away... I don't know how to do this with the Beta tags, as there is nothing in the Siteadmin. The cached object list is empty.

Hi, I looked at this yesterday, and ran it, but it didn't seam to make any difference. I couldn't tell if it did anything as there is no output. My current Cache settings in siteadmin are: Allow Caching: Yes Maximum Expiration 86400 Seconds (Appr. 1 Days) Maximum Cache Size 327680 Bytes (Appr. 320 K) Maximum Total Storage 52428800 Bytes (Appr. 50 M) Host Specific Caches: Yes Regards Daniel Parker -- This list is a free service of LassoSoft: http://www.LassoSoft.com/ Search the list archives: http://www.ListSearch.com/Lasso/Browse/ Manage your subscription: http://www.ListSearch.com/Lasso/ |

It doesn't look like this will work for the cache beta tags, which has a completely different strategy for cache storage. However you can pull some code out of the cache_maintenance tag to calculate the effective storage size. -- Mvh Johan Sölve ____________________________________ Montania System AB Halmstad Stockholm Malmö http://www.montania.se Johan Sölve Mobil +46 709-51 55 70 [hidden email] Kristinebergsvägen 17, S-302 41 Halmstad, Sweden Telefon +46 35-136800 | Fax +46 35-136801 -- This list is a free service of LassoSoft: http://www.LassoSoft.com/ Search the list archives: http://www.ListSearch.com/Lasso/Browse/ Manage your subscription: http://www.ListSearch.com/Lasso/ |

Since this is beta tags the reference doesn't mention them. And
lassotech neither. So where's the info on how to use them? In particular the Cache_Maintenance.
