hi Martin,
 
  monetdb version: 11.37.7-20200529
  sql: generic insert — INSERT INTO table(id,v1,v2,v3,v4) VALUES (…);
  test: same environment for both servers: vmbox 8gb, 4 cores, only one server is running on tests, no load of the host server
  php 7.4.5,  SQLAnyhwere pdo extension;  php-monetdb-1.0-1.el8.noarch.rpm
  script: same for both tests except connection, measured only loop execution,   the script uses «random» functions to
  generate  data for insert
 
 
function str_random($length = 3200)
{
    $pool = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    return substr(str_shuffle(str_repeat($pool, $length)), 0, $length);
}
 
 
  the execution time ratio for all tests was almost the same. each test was done on «clean» server.
 
  one of the test:
  monetdb:  Work: 796.90835905075 seconds
  SQLA:      Work: 382.80270600319 seconds

Hi <who am i talking to?>

There can be many reasons. Ranging from version used, SQL difference, test running, en PHP? API.
Based on the information provided this can not be judged.

regards, Martin
