I'm trying to follow this example: https://rpubs.com/cyclemumner/228100, especially the part where wms tiles with custum projection are added, but when I run the code I don't seem to get the wms tiles. I've installed leaflet from github.

recently working with ScheduleTask and I have such a question. I want that my ScheduleTask removes elements from my map every 5 seconds when map size more than MAX_SIZE field. I'm trying do this way:

Today I open my tiny app I'm using to learn Node.js with, together with Express and Sequelize.JS, but I suddenly encounter a problem, every time I want to log some object or array of objects or something like that (my app is tiny and also its objects) it takes really long and when the log comes it is monstrously long (of course that is syncronous so app freezes). It's like:

I'm working on adding a WMTS layer to my R Leaflet map using this url:

https://mrdata.usgs.gov/mapcache/wmts?layer=alteration&service=WMTS&request=GetCapabilities&version=1.0.0

I add the url into my code under the "addWMSTiles" option in R Leaflet like such:

So I've got a small REST API built with express.js and sequelize that I've refactored out into several files, because I wanted to be but in the process the .create() method for my models seems to have 'disappeared'. (I'm new to JS btw)

I'm using mapcache_seed in the mapcache package to create a large image cache from calling my mapserver WMS, with vectors.

Currently, this is the command I'm using:

sudo -u www-data mapcache_seed -c mapcache.xml -g WGS84 -n 8 -t Test -e\ [Foo,Bar,Baz,Fwee] -M 8,8 -z 12,13 --thread-delay 0 --rate-limit 10000

Where www-data is my Nginx system-user, mapcache.xml is my config, WGS84 is my SRS, -n 8 is my logical thread count (on a i7-6700HQ at 3200 MHz), -z 12,13 is one zoom level that needs to be seeded, thread-delay is off, and tile rate creation is set to 10000.

However, I only (max) get 50% total CPU utilization and most times only a single core goes above 50%. And an average of 500 tiles per second -- independent of how many threads or processes I specify. I've been trying to get all zoom-levels (4 to 27) seeded for the last couple of days, but I've only managed to get through 4-12, before being severely bottle-necked at a mere 3GB of a couple million tiles.

Memory utilization is at a stable 2.4% for 8GB PC4-2133 for mapcache_seed (0.5 for the WMS). Write speeds are at 100 MB/s, no-buffer write is also 100 MB/s, while buffered+cache is at 6.7-8.7 GB/s on a SATA III 1TB HDD. I have another SSD drive on my machine that gets 6 GB/s write and 8 GB/s read, but it's too small for storage and I'm afraid of drive failure from too many writes.

The cached tiles are around 4KB each and that means I get around 2MB worth of tiles every second. The majority of them aren't even tiles, but symlinks to a catch-all blank tile for empty tiles.

How would I go about speeding this process up? Messing with threads and limits, through mapcache_seed, does not make any discernible difference. This is also on a Debian Wheezy machine.

This is also being run through fast-cgi, using 256x256 px images, and disk cache with a restricted extent to a single country (otherwise mapcache starts generating nothing but symlinks to blank tiles, because more than 90% of the world is blank!)
